adult zebrafish as a model organism for behavioural genetics

This review frames adult zebrafish as a vertebrate model for studying complex behaviour and its genetic control. It highlights use across reward, learning and memory, aggression, anxiety, and sleep.

Using this model requires adult zebrafish behavioural assays and, for genetics-oriented work, isolation and molecular analysis of behavioural mutants.

It offers a way to connect behavioural phenotypes to conserved regulatory processes, genes, pathways, and neural circuits in a vertebrate system.

The abstract does not claim that adult zebrafish fully model all aspects of mammalian behaviour, only some aspects of complex behaviour.

The abstract contrasts zebrafish implicitly with mammals by emphasizing conserved processes between the two, but does not name specific alternative model organisms.
