Every year, the amount of cultivated seafood we consume is rising, making fishing an ever-more crucial source of nutrition and a reaction to overfishing. Nearly 99 million tonnes of aquatic animals ( fish, molluscs like oysters and mussels, and crustaceans like prawns ) were farmed around the world in 2023, five times more than three decades ago, according to the UN’s Food and Agriculture Organization. Underwater animal farming has consistently surpassed hunting worldwide since 2022, despite significant differences between species.
a types with quick growth:
The two biggest seafood on the market in 2023, carp and tilapia, primarily came from freshwater farming, whereas another widely consumed fish, like herring, only came from deep sea fishing. According to Thierry Laugier, a researcher at Ifremer, France’s national institute for ocean science and technology, fish farmers choose species that can develop quickly and with basic requirements to be able to handle the life cycle. Atlantic salmon, the fish that is most commonly planted in Europe, sold 1.9 million kilos in 2023, of which 97 % were farmed. We are aware of how to prevent aging or initiate a duplication period by injecting hormone, Laugier said.
Main supplier in Asia:
Asia is by far the biggest producer of farmed fish, making up 92 % of the 136 million tonnes of both animal and plant species produced under man-made problems in 2023. For fish, it comes down to history because it has been raised on the Asian continent for thousands of years, the Ifremer scientist said. Fish and herring are only caught in the waters for economic reasons, with some fish growing very carefully. According to Laugier,” It takes around two decades to get an adult-sized sardine.” He claimed that some fish have not yet been raised because” for a long time, we believed the lake was an inexhaustible source.”
Seaweed:
Although much known in the West, seaweed accounts for about a third of global aquaculture production. Seaweed output increased by almost 200 percent in the past 20 years, reaching 38 million tonnes, almost entirely from Asia. According to the expert, it is primarily used in business, in jelly, medicine, and cosmetics. He claimed that algae has the added benefit of absorbing both nitrogen and some substances in addition to CO2 in the oceans. It is also better to raise macroalgae than salmon, according to Laugier.
