Abstract
  • Triplicate groups of rainbow trout (Salmo gairdneri) fed six diets; five based on fish protein concentrate (FPC) ranging in caloric density from 4.36 to 6.19 kcal/g, and one based on vitamin free casein with a caloric density of 5.26 kcal/g were evaluated with respect to diet ingredient utilization. The parameters used to evaluate efficiency of diet utilization were: feed conversion, energy and protein conversion, and growth. The desirability of the edible portion of the fish produced on the different treatments from a flavor and texture standpoint was determined. The protein level was maintained at 38% of the dry diet, with 7.8% supplied by gelatin and the remainder by either FPC or casein. The herring oil levels of the diets ranged from 25% to 45% of the dry diet, and was the primary source of calories. Alpha-cellulose was included as a filler and ranged from 12.2% to 31.2% of the dry diet. The FPC based diets produced statistically superior weight gains when compared to the casein based diet. The efficiency of feed conversion was improved as the level of herring oil was increased. The energy and protein conversions were relatively constant for the FPC based diets, with the casein based diet being lower (P < 0.05).
