Major conveyor-belt sushi chains in Japan are stepping up efforts to secure sustainable marine resources amid the harsh situation facing the fishing industry, including continued declines in catch volume and a growing shortage of fishing operators.
They aim to ensure coexistence and mutual prosperity for people and the sea through a variety of initiatives, ranging from research on full-cycle aquaculture, which produces the next generation with eggs and sperm from adult fish raised from artificially hatched fry, to support for people employed in the fishing industry.
In 2024, Japan¡¯s marine fishery catch stood at 2.78 million metric tons, about a quarter of the peak level of 11.5 million tons in 1984. Seeking to reverse the negative trend, Food & Life Companies, which operates the Sushiro chain, began in June last year to sell ¡°artificial seedlings¡± of yellowtail developed in-house to aquaculture businesses.
