Criteria for Candidate Species for Aquaculture

Abstract

ABSTRACTThe nature of the animal taxa that are the most probable candidates for an intensive, commercial aquatic animal husbandry industry is considered. A characterization is presented of those biological criteria that lend the species the necessary physiological and genetic malleability to be adapted and molded into a domesticated race. The animal cultivated must be amenable to intensive management in high‐density confinements such as those now being engineered for high‐yield aquaculture. Attributes considered are discussed in the context of the various aquacultural ecosystems in which the species is expected to achieve satisfactory growth and survival. Together with bionomic criteria, economic requirements are posed and evaluated in an effort to define a socially and financially profitable agribusiness system. Investment requirements and operating costs are considered in terms of expected returns. However, since production alone is insufficient to sustain an enterprise‐i.e., the product must be sold‐production costs must be judged against market values. Therefore, ultimate use or consumer acceptance criteria are incorporated into the list of essential requirements for a candidate species for aquafarming.
