To decrease the phosphorus (P) load of fish farms, factors affecting dietary P utilization need to be known in more detail. A study was conducted to examine the effect of dietary calcium (Ca) level on dietary P utilization of Atlantic salmon reared in freshwater. Salmon fingerlings (initial weight 42.1 g) were fed a semi-purified diet (1.3 g kg -1 Ca, 3.1 g kg -1 P) with...
Amino acid availability values for Atlantic salmon were evaluated for two steam- and one flame-dried herring meal, menhaden meal, anchovy meal, and a Norwegian capelin meal (Norse-LT94 ). Apparent amino acid availabilities were calculated based on feces collected either by manual stripping or sedimentation (Guelph CYAQ-2 digestibility system). Apparent crude protein availability values obtained...
