| Summary: | This research was conducted in an attempt to improve embryonic survival of Labrador Arctic charr by altering the concentrations of lipid and vitamin E in the diets fed to broodstock. Four-year old Labrador Arctic charr broodstock were fed diets containing two levels of dietary lipid at two levels of vitamin E acetate (dl-a-tocopheryl acetate) supplementation. The diets were designated LLLE, LLHE, HLLE and HLHE to denote low lipid (12%)(LL), high lipid (19%)(HL), low vitamin E (30 mg/kg)(LE) and high vitamin E (600 mg/kg)(HE). For comparison, a fifth group was fed their normal diet - a commercial grower diet (COMM) containing 17% lipid and 100 mg vitamin E acetate/kg. Since Arctic charr broodstock used in this research were valuable, diets that might have a deleterious effect on the survival or fecundity of the broodstock could not be used. Dietary lipid concentrations were selected based on the requirements for juvenile Arctic charr. Dietary vitamin E concentrations were selected based on requirements stated ... |
