PERU fishing with guts to report…
One out of two pieces of fish we eat not from the wild. They are farmed. Will more tasty fish can be environmentally friendly?
The experimental farm of the National Institute for Agronomic Research, INRA in its French acronym, near Brest in France, participates in a European project to connect research centers in Aquaculture in the European Union.
The research geneticist Marc Vandeputte Engineer, stresses that "Aquaculture is an expanding activity that has been growing worldwide by more than 8 percent annually for twenty years.
Global demand for fish increases, while marine resources are stretched. So what we need is a sustainable way to produce more fish.
Vandeputte says, "as any aquaculture animal production consumes resources, particularly oil and fish meal which makes him a target for criticism. Also generates waste. "
Nutritionists and geneticists succeeded in replacing dietary fish most of the flour and fish oil with plant nutrients. Las Truchas, for example, are fed a strict vegetarian diet.
The researcher in fish genetics Edwige Quillet, INRA explains: "We have created a series of isogenic lines of individuals who are all from the same species and twins, genetically identical to each other and this feature allows us to be much
Various diets help understand how fish consume nutrients and to control fat and texture of the fish meat. Quillet says: "look good fish rearing, which is cheap and also to develop in a framework that pollute the environment as little as possible".
Is it possible to make the lives of farmed fish is better? At the University of Wageningen in the Netherlands, researchers use isogenic fish metabolism France to study thoroughly.
For Microbiologist Johan Schrama, fish nutrition expert and professor at the University of Wageningen "This research not only focuses on how to feed the fish, but also how to do it without damaging the environment.
The researchers measured the chemical changes of water fish all day.
Biologist Ep Eding, aquaculture researcher explains that "we can use this information to design the water treatment system.
Scientists hope that this investigation Fish future tastier, greener and cheaper.
