Yellowtail kingfish is farmed increasingly at more places. The young fish used for the aquaculture do not come from the wild. the farming in cages in the sea is not the most environmental friendly option due to fact that not eaten feed and waste come directly in the sea and diseases spread easily to and from wild fish. The management and feed used differs strongly between Asian countries and farms. At some farms industrial feed is used but there is also still feeding with locally caught small “trash fish”.
