American researchers have turned a carnivorous and gluttonous fish into a "vegetarian", hoping to protect smaller fish in the ocean food chain.

Cobia, also known as black salmon, is a fat and robust fish that specializes in hunting prey from crabs, squid and other small fish.

According to a report published in the Journal of Lipids, researchers at the University of Maryland in Baltimore sought to turn the cobia cultured into a plant-eating species, to reduce the pressure on populations of small fish in the ocean, which are already shallow. exhaustion due to over-exploitation of humans.

They hope that this approach will reduce the serious decline in the sardines community, which is the prey of many marine animals, including dolphins and swordfish .

According to The Washington Post, experts Aaron Watson, Frederic Barrows and Allen said they have synthesized plant proteins, fatty acids and ingredients such as amino acids commonly found in energy drinks to turn cobia into true cobia. object.

Michael Rust, who works at the US National Oceanic and Atmospheric Administration (NOAA), said fish, whether eating meat, plants or omnivores, also need about 40 nutrients in the diet.
