Some fish farming – and marine algae – is growing

Amount of Seafood We consume – as wild with our water – is growing every year, making it Aquaculture A significant source for many diets, and a reaction to overfing.According to the United Nations Food and Agriculture Organization, about 99 million tonnes of aquatic animals (fish, mollusks like oyster and muscles and crustaceans such as shrimp) were cultivated worldwide in 2023, which was five times more than three decades ago.Since 2022, the cultivation of aquatic animals has been ahead of frequent fishing worldwide – but with large inequalities from species to species.

Rapid growing species:

In 2023, the two largest vendors in the market, carp and tilapia, came mainly from freshwater cultivation, while other widely filled fish, like hering, came from deep sea fishing. A researcher of IFREMER of France’s National Institute for Ocean Science and Technology, Theory Logier told AFP that fish farmers choose species that grow with quick and simple needs to be able to control the life cycle.The most widely cultivated fish sales in Europe, the Atlantic salmon, reached 1.9 million tonnes in 2023, out of which 99 percent of the cultivation was done.“We know how to control aging or how to launch a reproductive cycle, through injecting the hormone,” the logier said.

Asia Main Maker:

Asia is the largest producer of cultivated fish so far, accounting for 92 percent of 136 million tonnes – for both animals and plant species – produced in man -made conditions in 2023.“For carp, it comes down to tradition, it has been cultivated on the Asian continent for thousands of years,” said the Eprimmer researcher.At the other end of the spectrum, sardines and herring are just fishing in the oceans, mainly due to profitability reasons because some fish grow very slowly.“It takes about two years to obtain an adult shaped sardine,” the logier said.He said that some fish cultivation has not been started yet, “For a long time, we felt that the ocean was an unwavering resource”.

see weed:

Very rarely known in the west, seaweed is still about one third of the world aquaculture production.Almost especially from Asia, Sewed production About 200 percent increased in two decades, up to 38 million tonnes. This is mainly used in the industry, in jelly, pharmaceuticals and cosmetics, the expert said.He said that seaweed also has the major advantage of absorbing CO2 in the oceans, but also nitrogen and some pollutants.“And from an ecological point of view it is better for Macrolega’s farm than the salmon,” the logier said.
