| Abstract | There is growing interest in growth-hormone transgenesis (TG) and triploidy (TRIP) in salmon aquaculture to shorten production cycles using fast-growing, reproductively sterile animals. Since triploidy alters physiology of fish and TG salmon have significantly enhanced growth rates, it is likely that feed formulations for conventional non-transgenic (NTG), diploid (DIP) culture may not be suitable. It is possible that traditional formulations may not provide TG/TRIP fish with sufficient macronutrients to sustain rapid growth and dietary micronutrient levels may require adjustment to reduce possible skeletal irregularities associated with triploidy. Evidence suggests that TG/TRIP fish may utilize dietary nutrients more efficiently, providing an opportunity to reduce feedcosts and improve the economics and ecological sustainability of salmon culture. This presentation will review a collaborative project conducted between industry and government to characterize and improve growth performance and nutrient utilization of TG and NTG TRIP salmon. Several studies are in various stages of completion focussing on several life stages; including first-feeding fry (<30 g), juveniles (30-300g) and large fish (up to 1 kg). These studies will provide information to help determine if diets for conventional NTG/DIP salmon are suitable for reproductively sterile fish and where further improvements may be required. Preliminary results will be presented. |
