There was relatively high
amount of fish fillets with gaping in the medium fish meal treatments,
but no significant effect of Schizochytrium sp. supplementation was observed
between the MF_0_Sc, MFM_25Sc and MFM_50Sc. Salmon fed
low fishmeal diets had significantly higher gaping frequency than salmon
fedmediumfish meal diets (13% units increase), but gaping frequency
was significantly lowest for salmon fed the low fish meal diet
supplemented with organic minerals instead of inorganic minerals.
