Carter, CG and Hilder, PE and Codabaccus, BM and Grunenwald, M and Adams, LR and Nuez-Ortin, WG, Feeding and nutrition of pre-harvest Atlantic salmon in seawater RAS at four temperatures, 17th International Symposium on Feeding and Nutrition of Fish, 05-10 June 2016, Idaho, USA (2016) [Conference Extract]
Pre-selected individuals showed wide variation in performance (Phase 2), individuals with condition factor of >1.2 were compared at 15 and 21°C. After more than 46 days at an elevated temperature (>19°C) there were few significant differences across growth, condition or muscle lipid. This indicated a level of robustness in a sub-group of salmon.
However, the performance of these more robust salmon was declining.
Large Tasmanian Atlantic salmon held at elevated temperatures (with 100% DO) in RAS declined in performance but continued to feed and grow for at least 7 weeks. Pigmentation appeared the most sensitive parameter measured.
