Abstract:
Aquaculture production is constrained largely by the growth efficiency of the species being produced. Nutritional approaches have played an important part in improving this situation, but, it is argued, the room for further improvement using such established techniques is limited. Alternative ways of improving fish production by utilizing recent biotechnological advances are explored and assessed as to their potential for commercialization in the near future. Transgenic technologies promise a revolution in aquaculture, but it is considered that consumer resistance may delay the use of transgenic fish for food production. An alternative approach could be the breeding of transgenic fodder plants without the amino acid deficiencies of existing alternatives to fish meal in aquaculture diets. The use of probiotics could reduce antibiotic use on fish farms while they might also provide the basis for ``smart'' diets, tailored to specific purposes by the inclusion of microorganisms. The selection and genetic engineering of nitrifying and denitrifying bacteria could also pave the way for fully enclosed, recirculating marine culture systems, which would allow control of the environmental variables that currently restrain marine fish culture.
