Physiological performance in aquaculture: Using physiology to help define optimal conditions for growth and environmental tolerance

摘要: Abstract In commercial fish aquaculture, it is crucial to ensure that environmental rearing conditions are adequate, if not optimal, for growth, welfare and profitability. recirculating aquaculture systems (RAS), where can be tightly controlled, targeting these optima may important in offsetting high costs. However, truly optimal growth rarely defined the literature. net-pen site selection permits some control over most relevant parameters; however, clear changes conditions, such as sub-optimal temperatures, hypoxia algal blooms, increasing frequency duration, often unpredictably. Thus, an understanding of how parameters affect physiological performance vital strains more resistant other unpredictable changes. this chapter we provide a framework based upon “Fry paradigm” defining values temperature, salinity water velocity performance, impact gill damage. We consider isolation, but also combination they co-vary culture environment. Furthermore, promote use stress tolerance tests predict ability withstand their environment arise due unforeseen circumstances. Finally, review various assays used quantify during parameters.
