00:06Hidden beneath the surface, the lives of thousands of species go unnoticed.
00:17In the western part of the state of Paraná, a group of Brazilian researchers seeks to reveal the
00:24Fish species from a river basin. This documentary follows them from the university,
00:34From the rivers and from dry land to the underwater world.

07:23Since our vision is generally limited to what is above the surface,
07:30Many of these interactions may end up going unnoticed.
07:34But the health of aquatic environments is interconnected with the health of terrestrial environments.
07:40This difficulty in observing what is happening below the surface.
07:43It also makes it difficult for us to perceive the impacts we have caused in these environments.
07:50A watershed is a natural boundary, the geographical feature that defines watersheds.
07:57By definition, a watershed is a set of landmasses.
08:02delimited by a watershed, by the main river and its tributaries.
08:09So, it's a natural, systemic, and integrated element.
08:13Everything that happens within these watershed moments will be directly reflected.
08:17in the watercourses present within this watershed.
08:26Especially in rivers and streams, but also to a lesser extent in larger rivers.
08:31Fish depend on matter and energy incorporated from the terrestrial environment.
08:38Whether for food or shelter.
08:58Some species are specialists and require specific environmental conditions for their survival.
09:07like the bungfish, while others are hardy and generalist,
09:13adapting to diverse conditions, like the lambari fish.
09:18All actions, all human activities that occur in the watershed,
09:23It has repercussions throughout the entire ecosystem.
09:27For example, the removal of riparian vegetation.
09:30The impact on all ecosystems, especially the rivers, is enormous.
09:37Because at this water-land interface, there are ecological interactions.
09:43So, if you remove the forest, that environment that, for example, provided land for water,
09:49Food for fish there, for example, a fallen fruit, a seed, a leaf.
09:54And habits, the complexity of habits that are organized there, for example, is important.
10:00So, if you remove that, the impact on fish diversity,
10:05not only in the fish, but in the biota as a whole, but it is really expressive there.
10:17A large portion of Brazilian fish are rhyophilic, meaning they have bodies that...
10:24Behaviors and life strategies adapted for living in environments with running water.
10:30However, human actions such as the construction of dams are transforming rivers from flowing water.
10:48in artificial, slow-moving water lakes.
10:54In these altered environments, species adapted to a sedentary lifestyle in calm waters
11:02They become abundant, while those that prefer flowing environments...
11:08These populations are drastically reduced or eliminated in these locations.
11:18Another significant human impact on the environment is the introduction of non-native species.
11:26In the upper Paraná River basin, dozens of non-native species have been introduced by humans.
11:33such as the Tucunaré, the Carazoiudo, the Caraporquinho and the Pacu Prata.
11:43These species may be favored by other human impacts.
11:48such as the alteration of the current environment in artificial lakes and the degradation of native vegetation.
11:56As a result, non-native species interact with other species.
12:03and can trigger chain reactions that impact all levels of organization within the environment.
12:11It's very interesting to realize that we participate in this dynamic equilibrium.
12:17After all, we are one species on the planet.
12:19And when human activity does not respect the limits imposed by the environment,
12:27A number of environmental imbalances can occur.
12:31For example, many species of fish control a large number of certain invertebrates.
12:38So there is a balance.
12:39If we break that link, problems will consequently start to occur.
12:46Then it starts turning into a domino effect.
12:51A river basin is a territorial management unit.
12:56precisely because it is a natural limit.
12:59And at the same time, besides being a natural limit,
13:03the Water Law, Law 9.433 of 1997,
13:08She defines that any and all environmental planning focused on water resources
13:15This should happen and should prioritize the Hydrographic Basin as the unit of study.
13:20Because all the processes that occur within these watersheds
13:24It will have repercussions throughout the entire river basin.
13:26Therefore, an environmental study should always prioritize the boundaries of a hydrographic basin.
13:33or a set of biographical basins, which is what we also define as biographical units.
13:39So these various basins can be useful for urban planning.
13:43rural planning, conservation projects, management projects,
13:48always aiming to improve the water quality of these watercourses.
13:54I think now is the time for us to really turn our attention to conservation.
14:02preservation and restoration.
14:09One of the first steps to conserve the Hydrographic Basin
14:14It's about getting to know the species that live there.
14:17Therefore, a group of Brazilian researchers,
14:20led by Professor Heleno Brandão,
14:24decided to investigate the fish fauna of a river.
14:29in the western part of the state of Paraná.
14:34The Paraná River Basin 3 encompasses a set of rivers,
14:38of sub-basins, which drain directly into Lake Taipu.
14:43The Taipu reservoir was flooded in 1982.
14:48shortly after the construction of the Taipu hydroelectric power plant.
14:51Therefore, a management unit was established.
14:55This management unit, called the Paraná 3 Hydrographic Basin,
15:00It is actually a hydrographic unit.
15:02with rivers located here on the Brazilian side
15:07And on the Paraguayan side as well.
15:09They all drain towards the Taipu reservoir.
15:12And within this network of rivers, we have one of the largest basins,
15:18which is the São Francisco River basin.
15:20We have the False San Francisco basin and the True San Francisco basin.
15:25North Branch and South Branch.
15:27And these basins, being the largest basins in BP3,
15:33They are of greater importance.
15:35In other words, everything that happens in this False São Francisco basin,
15:41in the São Francisco Verdadeiro basin,
15:42This is directly reflected in Lake Taipu.
15:44It is very important that science be part of the data that supports decision-making.
15:52Investigating environmental impacts, for example,
15:55In many cases, it can be limited by a lack of information about local biodiversity.
16:01That's the importance of wildlife inventories.
16:03Because they provide a historical record of the current state of biodiversity.
16:14The goal of a species inventory is to identify the organisms that live in a given location.
16:22bringing together a range of information, such as scientific names,
16:28geographical distribution,
16:31abundance of individuals and conservation status.
16:37But behind a list of species,
16:40What lies beneath is a difficult task that begins with research and planning.
16:46the best methods and locations for capturing the species.
16:54The research team selected 12 fish collection points along the watershed.
17:02Six locations were selected along the main canal.
17:09In six others, in smaller rivers, which flow towards the main channel.
17:19For one year, each of the twelve locations was monitored every three months.
17:25totaling 48 samples from the basin.
17:29To conduct a thiofaunal survey,
17:33It's a number of factors that need to be taken into consideration.
17:38The first point is planning.
17:42You have to take financial resources into consideration.
17:45the team, the structure,
17:47And then you'll determine the mosaic you want to sample.
17:53And this sampling has to be representative.
17:57Otherwise you won't be able to answer the questions.
18:01Species survey work
18:03It begins long before going into the field to collect the specimens,
18:08and they end long after you have that data.
18:26First, it's very important to define things clearly.
18:29What is the objective of the work?
18:31and to define what the best equipment and methods will be.
18:36to achieve that goal.
18:38So, a plan is made,
18:39where is it decided where these species will be collected?
18:44How often will these species be collected?
18:47For how long?
18:48And it's a good practice to minimize the possibility of error.
18:52During expeditions, the task is to organize the equipment.
18:55well in advance,
18:56and a conference at the beginning of all expeditions.
19:07The São Francisco River, a false northern branch,
19:11It is not navigable in many sections.
19:15So, the expeditions to the fish collection points
19:20They occurred by land.
19:24Throughout the research,
19:27the team traveled approximately
19:282,250 kilometers,
19:33with an average of 563 kilometers
19:37by expedition,
19:39and 117 kilometers per day.
19:45To choose the sample points,
19:47We work with the Google Earth platform.
19:50From this platform,
19:52we mapped out the routes,
19:54we selected the roads,
19:55and we studied access
19:58to the point
19:59that's what we'd like to achieve.
20:01Always before going to the field,
20:04The meetings were taking place,
20:06then each member of the team
20:07I already knew what I was going to do out on the field.
20:10We would put, for example,
20:11We work with an Excel spreadsheet.
20:14So we assigned roles to everyone.
20:16Of course, when we get there on the field,
20:17They help each other.
20:18Without a doubt, but we already had a focus.
20:21And I think that helped a lot.
20:27Species that are very similar to each other.
20:29They make it difficult to identify the fish while still in the field.
20:34For this reason,
20:36the collection of individuals and subsequent identification in the laboratory.
20:41It is indispensable for a fish inventory.
20:45Scientific collection,
20:47carried out in accordance with the law
20:50and duly authorized by CISBIO,
20:53it does not have a significant impact
20:56natural populations.
20:58In truth,
21:00this practice contributes in a crucial way
21:03for the conservation of species,
21:05because each specimen captured
21:07It brings with it a set of data.
21:10about your biology
21:12which may be investigated
21:14for future research.
21:16It is very important that species inventory surveys
21:20manage to register reliably
21:24that community that lives there.
21:26And in order for that to be possible,
21:28It is interesting to use a variety of methods.
21:31that allow exploration of different aquatic environments,
21:35such as different depths,
21:38different types of substrate,
21:39such as sand, gravel or stone substrates,
21:43The presence of tree trunks, for example.
21:45In our case, we use four pieces of equipment.
21:53We use a set of waiting networks.
21:56with mesh sizes of 3 to 7 centimeters
21:59which were exposed to the environment for approximately 12 hours.
22:03This is a method that consists of a rectangular grid.
22:07with different mesh sizes
22:09which will capture the fish that pass through these meshes.
22:17We use sieves
22:19which are important for collecting small species
22:23that live near vegetation or on the banks of rivers.
22:33We also use the trawl net.
22:36which consists of a large rectangular net
22:38which is being pulled by two people towards the shore.
22:42And we also use a set of fishing nets.
22:45which consist of a circular network
22:48with weights on the margins
22:50which is launched and opens while still in mid-air.
22:52and it catches the fish as they fall and sink into the water.
22:58The wide variety of formats,
23:01sizes and behaviors of fish
23:05reflects the different environments
23:07that the species occupy.
23:11To capture as many species as possible,
23:16researchers should use
23:18a set of appropriate techniques and equipment
23:21to different aquatic environments,
23:24because different environments
23:26They also shelter different species.
23:32And there is a certain selectivity.
23:35within each of these methods.
23:38For example, waiting networks
23:41They are best for capturing medium-sized species.
23:43large size,
23:44while the other methods are better
23:46to capture small species
23:48which represent a significant portion
23:51of the diversity of freshwater fish in Brazil.
23:55In many cases, species survey research
23:59They need to remove the fish from their natural environment.
24:03and include them in scientific collections.
24:09To reduce animal suffering,
24:11Lucas prepares an anesthetic solution.
24:14based on clove oil
24:16for the euthanasia of fish.
24:18In the field, immediately after collecting the fish,
24:23They are transferred to this anesthetic solution.
24:27This procedure guarantees the fish
24:30a quick death
24:31and with as little stress as possible.
24:33When we receive the fish,
24:36after euthanasia,
24:37We generally use the formal 10%.
24:40We apply the formal 10%
24:43evenly distributed throughout the fish's body.
24:47Then we put these animals in drums.
24:50also containing the 10% formaldehyde.
24:51After we remove it from the formal framework,
24:54We transfer these fish to drums filled with 70% alcohol.
24:58And these fish will be kept inside these drums with 70% alcohol.
25:01for an indefinite period.
25:02These organisms, they will receive a humerus, a Bosch.
25:08These fish are made available to the scientific community.
25:10and also the external community.
25:12From these organisms,
25:13Researchers can do work on evolution,
25:17phylogeny, systematics, ecology,
25:21in numerous works.
25:23In addition, the collection also contributes works with a specific focus on education.
25:29We receive students from the public school system.
25:32private network, through workshops.
25:35So, there is a contribution to the external community.
25:39And also, you know, with the scientific community.
25:47The small Mato Grosso fish, popular in aquariums.
25:51It has a bright red color in nature.
25:57But after preservation in alcohol,
26:00It features only a yellow background color and black pigments.
26:07Fish taxonomists,
26:10scientists specializing in the identification and classification of species,
26:16They generally describe the species.
26:18based on animals preserved in alcohol.
26:26After collecting the specimens and attaching them,
26:30We carried out an initial screening, a separation,
26:33based on the main visible characteristics,
26:36such as size, body shape, and coloring patterns.
26:39Each of these possible species,
26:43which at first we call morphotypes,
26:45They are separated according to morphotype, right?
26:49The location of the capture and the date.
26:56Of all the individuals captured throughout the four expeditions,
27:00whether they are big or small, one by one,
27:03Lucas separates them according to the species, location of capture, and date.
27:09The similarity between some species can hide
27:13a diversity of species that is still little known.
27:18After the initial separation,
27:21a new, more rigorous analysis is performed,
27:24paying attention to details,
27:26such as the number of scales,
27:29fin rays and the number and shape of teeth.
27:34Each of these possible species
27:36It will be re-analyzed to arrive at the lowest level.
27:40in the lowest possible identification category,
27:43which is the species.
27:44To do this, in the case of fish, for example,
27:47We need to obtain some data from those animals.
27:52and compare this data with the scientific literature,
27:57Published articles or books.
28:00And we can also make direct comparisons.
28:04with other fish that are kept in collections and museums.
28:09In some cases, it is also important to do
28:12some chemical procedures that reveal certain characteristics,
28:15such as, for example, the skeleton,
28:17and some identifications can only be confirmed
28:19if these procedures are carried out.
28:23After identifying the species,
28:26We need to deposit some of this material.
28:31in collections and museums,
28:33because this material will serve as evidence.
28:36of that record in that location,
28:40In addition to serving as a data source for various research projects.
28:44After confirming the identity of all species,
28:49The inventory is complete.
29:20THE CITY IN BRAZIL
29:33Below the surface of flowing water
29:36from the São Francisco River basin, False North Branch,
29:41They swim hidden from human sight.
29:4458 species of fish.
29:47of species that are no more than a few centimeters long
29:51to large and powerful predators.
30:02The group of fish with the largest number of species includes
30:06those popularly known as Lambaris
30:10and Tetras.
30:14Only in this family,
30:1621 species were recorded in the basin.
30:25Hidden by the turbulent waters,
30:28Lambari fish form large schools.
30:31And they are here for a reason.
30:39Food
30:44Lambari fish keep swimming constantly.
30:48and they wait for food carried by the current.
31:12Lambari fish, like many other species of fish,
31:16They depend on food produced in the terrestrial environment.
31:24For thousands of years,
31:26the relationships between species
31:28They supported an abundance of life in the Atlantic Forest.
31:33creating intimate relationships between freshwater fish
31:37and a healthy forest.
31:40Anthropogenic use is quite important.
31:43when we talk about watershed conservation.
31:45Because when you use it properly,
31:48In other words, when riparian forests are well preserved,
31:52when the springs are well preserved,
31:55when urban, rural, and industrial activities
31:59They respect these limits.
32:01the boundaries focused there on the preservation areas,
32:06We tend to have a good environmental quality.
32:09largest in the river basin.
32:11In other words, if you have proper use with management and conservation practices,
32:16This whole system tends to become balanced.
32:20In contrast,
32:22when we misuse it,
32:24For example, when we occupy water sources,
32:27when we deforest right up to the riverbed,
32:31when we release pollutants improperly
32:36with a very high load in the watercourses,
32:39We are generating a series of processes.
32:41which have been degrading this watershed over the years.
32:46Especially when we think about high-impact activities.
32:50So, if you can make good use of it,
32:54good planning,
32:55if you can control the amount,
32:57to monitor the amount of pollutants reaching this river,
33:01automatically this watershed
33:03It tends to have a higher environmental quality.
33:06In other words, it tends to be a more preserved basin.
33:08with cleaner rivers and better-preserved springs.
33:11And all of this is quite important.
33:12When we think about the fish that are present in these rivers,
33:18when we think about the entire biota
33:20and all the ecosystems present within that watershed.
33:23Works with a conservation focus
33:25They bring knowledge that will aid countless strategies.
33:29It depends on the ecosystem, it depends on the watershed.
33:33Each river basin has its own specific characteristics.
33:37So, these jobs are distributed across the planet.
33:40assists with innovations to mitigate the impacts.
33:46inherent to the present time.
33:49So, in our work, for example,
33:51We record some non-native species.
33:54And the impact of these non-native species,
33:57They are quite intense.
34:00causing, in many cases, even
34:02the extinction of other species
34:04or the decrease in species diversity
34:08in that particular ecosystem.
34:15In the Itaipu reservoir,
34:18A non-native fish has taken over this environment.
34:23the yellow peacock bass
34:28This species is native to the Tocantins and Araguaia river basins.
34:33but it was widely introduced by man
34:36in various rivers in Brazil and around the world.
34:40Especially in reservoirs.
34:44But where its presence is not natural,
34:47This species causes worrying impacts on the environment.
34:52The tucunaré, in the Amazon basin region,
34:55It has an importance in the ecological cycle.
34:58within the tropical niches there,
35:00from that region.
35:01But when this animal is introduced
35:03to other locations, to other river basins,
35:07Yes, he does cause harm.
35:09a negative impact on that ecosystem,
35:13because it goes to the place of other predators,
35:17He ends up succeeding at it.
35:19and that will cause, for example,
35:20the decrease in species diversity
35:22from that particular region.
35:25Unlike most native species of the Paraná River,
35:30The peacock bass is adapted to living in slow-moving water environments.
35:35establishing themselves well in reservoirs.
35:39But another characteristic that favors its establishment
35:43It's their breeding strategy.
35:51While many native fish do not care for their offspring,
35:58Tucunaré fish protect their eggs and offspring.
36:02to guarantee the survival of future generations.
36:12With the fins and pectoral fins,
36:15The females move the water to oxygenate the eggs.
36:27While the male
36:29scares away any potential predator.
36:37including other peacock bass.
36:51Parents protect their offspring.
36:53until they are big enough
36:55to survive on their own.
37:02Every spring and summer,
37:05the banks of the reservoirs are infested
37:08for thousands of peacock bass fry,
37:10which will feed on small fish
37:13and offspring of other species.
37:20A study conducted at the Rosana reservoir,
37:23in western São Paulo,
37:26monitored the fauna of small fish
37:29that live in association with aquatic plants
37:33Before and after the introduction of the peacock bass.
37:38And what does this study reveal?
37:40It's that some years after the introduction
37:41of this species,
37:42There was a reduction of approximately 80%.
37:45in species diversity
37:47and a 95% reduction
37:50in the number of individuals,
37:52that is, in abundance
37:54of these little fish
37:55that live in these plants.
37:58And a few years later,
38:00a new study was carried out
38:01which correlates these impacts
38:04with the reproductive dynamics of the peacock bass
38:07and with the large shoals
38:09of offspring of this species
38:11who will feed
38:12of these small species
38:14or offspring of other species.
38:21The big-eyed yam
38:24and the little pig
38:26These are other examples.
38:29of non-native species
38:31abundant in the Itaipu reservoir.
38:36Just like the yellow peacock bass,
38:38These species are native.
38:40from the Tocantins-Araguaia basin.
38:42But the reason for its introduction
38:46in the Paraná River basin
38:48It was probably trade.
38:51as an ornamental fish.
38:54The colors are beautiful.
38:59Both species also
39:00They take care of their offspring.
39:03And the little pig
39:07employs a behavior
39:09even more sophisticated.
39:11At the slightest sign of danger,
39:17the pups swim
39:19towards the parents
39:20and these guard them
39:22safely inside the mouth.
39:42When a species
39:43is introduced
39:44in a given environment
39:46by N factors,
39:49It's very difficult.
39:50if you remove it from the environment.
39:51We always leave
39:53this warning,
39:54this care
39:54of importance
39:55to avoid
39:57the introduction
39:58of non-native species
39:59because of the impact
40:00that occurs
40:01in the ecosystem
40:02It will cause harm.
40:04much bigger
40:05sometimes in the short term,
40:06in the medium and long term.
40:12Of the 58 species captured,
40:155 are originated
40:17from other regions
40:18from South America,
40:19like the tucunaré,
40:22while tilapia
40:24is native
40:25from the African continent.
40:29Five other species,
40:30like the young girl,
40:35They have an identity.
40:37complex scientific
40:38which will need to be
40:40carefully evaluated
40:41for future research.
40:43So that one can study
40:46and understand
40:47biodiversity,
40:48It is very important.
40:49that all species
40:51receive
40:51a scientific name.
40:53That's because,
40:54different from the names
40:55popular,
40:56which may vary
40:57from region to region,
40:59or they can group together
41:00various species
41:01about the same name,
41:02scientific names
41:03They are more accurate.
41:04and enable
41:06which scientists
41:07from anywhere
41:08of the world
41:08manage to talk
41:10each other
41:11about that
41:12a particular species.
41:13There is a science
41:14responsible for classifying
41:16and to name
41:17all of biodiversity,
41:18That is taxonomy.
41:26in environments
41:28with strong currents,
41:31the young girl
41:32hold on
41:32at the bottom of the river
41:33with the help
41:35of rigid bones
41:36in the fins.
41:40Without a glance
41:42attentive,
41:45these micro-predators
41:49they can pass
41:51easily
41:51unnoticed.
41:56Besides not growing
41:57more than
41:58a few centimeters,
42:00its coloring
42:02It's camouflage.
42:04perfect.
42:06Some studies
42:07taxonomic
42:08reveal,
42:09for example,
42:09that the species
42:10that we captured
42:11here on the river
42:11False Saint Francis,
42:13popularly known
42:14like a young girl,
42:15in truth,
42:16belongs to a
42:16species complex
42:18and possibly
42:19It shelters various species.
42:20very similar
42:22each other,
42:22that they will need
42:24to be better
42:24investigated
42:25in future studies.
42:26And only then
42:27these new studies
42:29that
42:30will be possible
42:31determine
42:32what exactly
42:33the species
42:34that occurs
42:35here in our region
42:36and its distribution
42:37geographical.
42:38Good,
42:39this work
42:39It is important
42:40because it shows
42:41what are the species
42:42that occur
42:43here in the region.
42:44the objective
42:45main
42:45It's about conducting the survey.
42:47of the fauna
42:48of the species
42:49fish
42:49of the river
42:50Fake Saint Francis
42:51in our north.
42:52Yet
42:52It's a gap.
42:55in science,
42:55so now
42:56we succeeded
42:56to fill in
42:57with this work.
42:59We're going too.
42:59offer
43:00the identification key
43:01of the species
43:02of these species
43:04that we
43:05we collected,
43:06we registered
43:07to be used
43:08in jobs
43:09futures
43:10and especially
43:12with focus
43:13in preservation
43:14and conservation.
43:16Hence the importance
43:17yet
43:18investment
43:19in this area,
43:20in the area of ​​conservation,
43:21of preservation
43:22and restoration
43:23of ecosystems.
43:34we live
43:35in a world
43:35changing
43:39and us
43:41We are changing it.
43:47We know
43:48just
43:49a fraction
43:50of the species
43:50that they share
43:51this world
43:52with humans.
43:56and our actions
43:57can become extinct
43:59countless
43:59species
44:00even before
44:01that we may
44:02to meet them.
44:04The complex
44:06river network
44:06Brazilians
44:07it houses a huge
44:08invisible diversity
44:10hidden
44:11from the human perspective.
44:13To unravel
44:15what lives
44:16below the surface,
44:18the teacher
44:19Heleno Brandão
44:20and his team
44:20they needed to overcome
44:22numerous challenges.
44:26the team
44:27performed
44:27collections
44:28of fish
44:29standardized
44:30for a year
44:30in the basin
44:32of the river
44:33Saint Francis
44:34False
44:34North Arm
44:35in the west
44:36from Paraná.
44:38They identified
44:39all the material
44:39collected
44:42and deposited
44:44examples
44:44in collections
44:45scientific.
44:46the researchers
44:49the researchers
44:50they found
44:5258 species
44:53of fish
44:54that depend
44:55of the natural flow
44:56of the rivers
44:57of the vegetation
44:59terrestrial
45:00and compete
45:01for survival
45:03against species
45:04non-native.
45:06The fish
45:08they play
45:09functions
45:10important
45:10for health
45:11of the environment
45:12and for well-being
45:13of human beings
45:14and so that
45:16preserve
45:17this big
45:17diversity
45:19it is necessary
45:20first
45:20to meet her.
45:44Yeah, it's short, isn't it?
45:46The rope is short.
45:50Only those who use
45:51It's just that he doesn't like it.
45:56Is it being filmed?
45:57Yes, he's going to edit it.
45:59It won't happen.
46:00I'll leave it as is.
46:00It could be that...
46:11Do you want to throw me?
46:11Things are like that, right?
46:13Hey, Lucas,
46:13It's not working, man.
46:14She turns around.
46:15I want to film.
46:16You guys down there.
46:17She's in mode
46:18Tilt locked.
46:20You will need
46:21arm
46:22to raise that even further.
46:26Hi, John.
46:27Yes.
46:28You need to bring
46:28What's your name?
46:31Let's go.
46:33A snake.
46:34A snake, right?
46:35To where?
46:35He walked.
46:37It's gone out again.
46:39Yes, I see, I see.
46:40See?
46:41Is it winding around?
46:41I am.
46:41AND.
46:44I'm wearing the wrong lens.
46:46It doesn't work.
46:47Let's go this way,
46:47Go this way.
46:47AND.
46:48How beautiful, huh?
46:50How wonderful.
46:51Now it's good.
46:54THE.
46:56That it?
46:57Now it's a water breed.
46:59Damn.
47:01He caught a big one there too.
47:04He doesn't have it in his hand.
47:14Come, come, come, come, come.
47:15Come on, I didn't see you.
47:16Come here.
47:17There's some clay.
47:17There's some clay.
47:17There's mud in the water.
47:18A crab.
47:20Here, look.
47:21Guys, two hours, huh?
47:22Okay, we're just going.
47:24How will it turn out well?
47:25The guys call us too.
47:27Yes, but there's another good point.
47:29There's another little creature.
47:30There's another stream.
47:32Two crabs.
47:32And the...
47:33Oh, it's going to be good.
47:34And the worst part is the kayaking spot.
47:36Yes yes.
47:37But it's crazy tomorrow, no worries.
47:38Yes.
47:39No, perfect.
47:40Right?
47:41This spot right here, man.
47:43Three crazy people, I think the chair is difficult.
47:50That's why I told you we wouldn't be able to make the stream today.
47:53No, that climb, that day when we...
47:55On the two occasions that we were alone, without support, he climbed up carrying the kayak in his hand.
47:59You have no idea.
48:00We take about three steps, the arm goes to find the image and stops.
48:02I can imagine, man.
48:05I don't need anyone.
48:07I don't know.
48:08I don't know.
48:10Very lazaretto.
48:12This spot is the same as the lazaretto.
48:14I don't know.
48:15I don't know.
48:16Thanks for watching.
