USE OF OIL, SOLVENT-EXTRACTED MEAL AND PROTEIN CONCENTRATE FROM CAMELINA (CAMELINA SATIVA L. CRANTZ) FOR SALMONIDS AT THE EARLY LIFE STAGE

Abstract

Studies were conducted to evaluate the effects of using camelina products including camelina oil (CO), solvent-extracted camelina meal (SECM) and camelina protein concentrate (CPC) as feed ingredients for salmonid fish at early life stages. Replacing up to 100% fish oil with CO had no adverse effect on growth performance of first feeding rainbow trout (0.105 g), Atlantic salmon fry (1.1 g), and rainbow trout fry (1.0 g). Diet with the highest SECM inclusion rate tested, 18%, significantly increased feed consumption and subsequently weight gain of first feeding trout. Both salmon and trout fry performed well on 18%SECM diet (p>0.05). The 18%CPC treatment resulted in over 50% mortality rate of first feeding trout and significantly poorer growth after 56 days. The highest level of CPC tested, 12%, in trout fry diet did not lead to any difference in growth when compared to remaining treatments.
