WebDec 6, 2024 · The amount of fish meal or fish oil used per metric ton of fish or shrimp production will decline with lower FCR. If the feed requires 700 kg live fish equivalent/t feed, the fish in-fish out ratio (FIFO) would be 0.84 at FCR = 1.2, but 1.26 at FCR = 1.8. Benefits of lower FCRs. Reducing FCRs has tremendous benefits.
