To avoid emptying the oceans, fish are made in labs
While overfishing and climate change threaten fisheries resources, some are developing solutions to produce fish from cells.
A day will come, in the near future, when we will no longer eat natural fish. On that day, the Japanese will take out of their freezer tuna grown from cells. Artificial fish fillets are already being produced in the United States.
Despite conservation efforts, the quantity of sea fish has dropped sharply. If it is more difficult to obtain marine products, thanks to advances in technology there is no longer any reason to be solely dependent on natural fish. While this vision of the future is difficult to accept, it is not inconceivable.
Global warming and overfishing are predicted to cause the collapse of the marine ecosystem, and many fish are doomed to extinction. A report by the Food and Agriculture Organization of the United Nations (FAO) indicates that the proportion of sustainable fisheries resources, which stood at 90% in 1974, fell to 66.9% in 2015. According to a study by the Fisheries Information Centre, Japan's sea fare catch was limited to 166.2 tonnes last August, up from 7,000 to 8,000 tonnes previously.
What is new, with the recent decrease in fish catches, is the emergence of "cellular fishing", a technology under development. Professor Goro Yoshizaki of tokyo University of Marine Science and Technology and his team have developed a technique to proliferate in vitro primordial germ cells [of fish] that form the common origin of male and female reproductive cells. These can be recreated at any time from a stock of cells and it is enough to make them meet to obtain fry. In other words, the laboratories will become the fishing grounds of tomorrow.
