Marine aquaculture: Genetic potentialities and pitfalls

Abstract

Genetic considerations permeate the intricate interactions of marine aquacultural populations with their wild counterparts. We illustrate these complexities in a matrix where seven categories of primary aquaculture activity (conservation, supplementation, mitigation, intentional introduction, put-and-take, commercial captive rearing, experimental) are linked to important genetic considerations related to resident and cultured taxa. We focus on the effects of cultured populations on their wild native conspecifics. Using published examples, we examine both the frequency of occurrence and the biological implications of situations in which released cultured fish have had direct genetic effects through introgressive hybridization, as well as indirect genetic effects such as induced through disease transfer, induced over-harvest, and displacement. These examples are contrasted with those instances where aquacultural activities have coexisted in harmony with underlying concerns related to issues of conservation genetics. Recommendations are made to guide industries, agencies, and managers toward these latter interactions.
