00:00My name is Alexis Araujo Quintero, I'm from Venezuela,
00:03I'm an ornitologist at the National Experimental University of Los Llanes, Ezequiel Zamora,
00:08and in this expedition I'm working on determining the richness and the composition of aquatic species
00:15and terrestrial species that can be found during the journey.
00:19What do you want to know?
00:26Those peces can, in a way, accumulate certain disorders like heavy metals,
00:33or other contaminants that can be found in the river.
00:37The fish can feed the fish, and this process, in a way, is transferring
00:45what the fish have accumulated, they can be transferred to the fish.
00:49The fish can also be an indicator of some disorders that can occur in the water bodies.
