Hematology & Blood Chemistry for Fish; Evaluating the Contribution of Nutritional Feed Additives

Blood analysis tests provide extensive information regarding the fish’s health state and wellbeing. Therefore, when evaluating a new feed additive, the hematological and blood chemistry analysis can provide essential information regarding the product’s mode of action and its impact on the fish. Despite the fact that there is no novelty in this approach, to date not many researchers know how to correctly interpret the results. We will review the crucial contribution of blood tests as a tool to analyze the effect of nutritional feed additives for fish.
