According to the FAO, Fish In Fish Out is the number of tonnes of wild fish that takes to produce a tonne of farmed fish. The calculation is done according to the following formula:

Selecione uma das seguintes:

FIFO = ((FM in feed%)/(FM yield from wild fish%) + (Level of FO in the feed)/(yield of FO from wild fish %))xFeed: gain ratio;
FIFO = ((FO in feed%)/(FM yield from wild fish%) - (Level of FM in the feed)/(yield of FO from wild fish %))xFeed: gain ratio
FIFO = ((FM in feed%)/(FM yield from wild fish%) + (Level of FO in the feed)/(yield of FO from wild fish %))/Feed: gain ratio
FIFO = ((FO in feed%)/(FO yield from wild fish%) - (Level of FM in the feed)/(yield of FO from wild fish %))xFeed: gain ratio
FIFO = ((FO in feed%)/(FM yield from wild fish%) +(Level of FM in the feed)/(yield of FM from wild fish %))/Feed: gain ratio
