00:00Myth versus fact. Throughout human history we have told stories about the great creatures of our world
00:06and the giant Japanese carp is no exception. These magnificent fish, often called koi,
00:14glide through garden ponds like living jewels, their vibrant colors a flash of brilliance beneath
00:20the water's surface. But with their impressive size and ancient lineage come tales of immense
00:26power and mystical abilities, some of these stories hold a kernel of truth, others are flights
00:33of fancy. Today we shall embark on a journey to understand these giants, to separate the legends
00:39from the biological facts, and to discover why these remarkable fish hold such a special place
00:46in our world. What exactly are these giant Japanese carp? They are a domesticated variety of the common
00:54carp, Cyprenus carpio. In the quiet, mountainous regions of Japan, rice farmers centuries ago began
01:03to notice natural color mutations. Instead of the usual drab gray or brown, some fish displayed patches
01:10of red, white, gold. These unique individuals were selectively bred for beauty. This careful,
01:18patient process spanned generations of both fish and humans. It gave rise to nishikigoi, or brocaded carp.
01:27One of the most dramatic myths whispered about giant carp is that they possess the strength to pull a
01:33person underwater. It's a compelling, almost monstrous image, but it is pure fiction. While a fully grown
01:41giant koi is undeniably powerful, its world is the tranquil, contained environment of a pond, not the
01:49open, deep waters, where such a danger might even be conceivable. Their strength is used for navigating
01:57their aquatic home, and occasionally for powerful bursts during spawning season. A large, curious carp
02:04might gently bump against a hand offered at the water's surface, its mouth searching for food,
02:10but the notion of it being a threat to human life belongs firmly in the realm of folklore,
02:17not natural history. Another pervasive belief is that koi are direct bringers of luck and wealth,
02:24magical talismans swimming in one's garden. This idea is deeply rooted in Eastern philosophy and
02:31symbolism, particularly feng shui. While the fish themselves possess no supernatural powers to alter
02:38one's financial state, their symbolic value is immense. They represent perseverance, as they are known to
02:46swim against strong currents and success. Giving a koi as a gift for a new business or home is a
02:53gesture of
02:53profound goodwill. The luck they bring is not magical but rather a reflection of the positive human values,
03:00strength, ambition and beauty that we project onto them. Just how large can these living jewels become?
03:06Under optimal conditions, a giant Japanese carp, or jumbo koi, can grow to be well over 90 centimetres,
03:15or 3 feet, in length, and can weigh more than 15 kilograms. The record holders are even larger.
03:22This remarkable size is not achieved quickly. It is the result of many years of steady growth,
03:28influenced by a trio of critical factors. Genetics, diet environment. Just as with any great creature,
03:36lineage plays a role. The offspring of large parents have a greater potential for size. However, without
03:43ample space to swim, and a high-quality protein-rich diet, that genetic potential will never be realized.
03:50The diet of a carp reveals its adaptable nature. They are omnivores, equipped to forage for a wide variety
03:58of foods. In a natural setting, they would use their sensitive barbels to sift through the pond bottom,
04:04insects, crustaceans, algae, plant matter. In Japan, the koi is far more than just a beautiful fish.
04:11It is woven into the fabric of national culture and identity. Its image appears everywhere. Exquisite
04:19works of art, intricate tattoos, festive flags that flutter in the spring breeze. The carp embodies
04:26virtues. Courage, strength, perseverance against adversity. A determined carp swimming up a torrential
04:34waterfall on the Yellow River. As a reward for its incredible effort, the gods transformed it into a
04:41powerful celestial dragon. The tale became a timeless allegory for success through hard work
04:47and determination. Um, you know, it's really a quiet kind of reverence. Um, well, you know, these are the fish
04:55the fish we will meet, um, well, you know, the fish we will meet, um, well, you know, the fish
04:55we will
