Environmental enrichment and fish welfare

Environmental enrichment promotes neural plasticity and cognitive ability in fish.

Different kinds of experience during early life can play a significant role in the development of an animal's behavioural phenotype. In natural contexts, this influences behaviours from anti-predator responses to navigation abilities. By contrast, for animals reared in captive environments, the homogeneous nature of their experience tends to reduce behavioural flexibility. Studies with cage-rea...

Key issues concerning environmental enrichment for laboratory-held fish species.

An improved knowledge and understanding of the fundamental biological requirements is needed for many of the species of fish held in captivity and, without this knowledge it is difficult to determine the optimal conditions for laboratory culture. The aim of this paper is to review the key issues concerning environmental enrichment for laboratory-held fish species and identify where improvements...

Enrichment of fish eggs with ascorbic acid

Success in aquaculture depends on the mass production and quality of juveniles. However, many fish species suffered high losses during the early stages of development. Therefore, in order to decrease mortality, produce a large number of healthy larvae is a fundamental issue. On the other hand, one of the micronutrients that can be effective in larvae health is ascorbic acid. During the embryoni...
