The application of science and technology development in shaping current and future aquaculture production systems

Abstract

SUMMARYAquaculture development over the past 50 years has been facilitated largely by the application of science and the introduction of new technologies. Although aquaculture is a very diverse sector in products, production systems and business structures, almost every activity has benefited from scientific advances. However, the impact of technological progress is most clearly seen where there has also been substantial industrial consolidation. This has provided greater capital resources for investment and a more attractive market for suppliers of innovations to target. It has also encouraged consolidation of research capacity and stronger articulation between private and publicly funded research efforts. Further development along current trajectories is possible through advances in genomics, information technology, materials science and other areas. However, there may also be substantial disruptions if, for instance, energy becomes much more expensive, or large mono-cultures are impacted by climate change. Substantial change could also be driven by policies that aim at bringing realistic external costs of environmental services into company accounts. Research into more resilient aquaculture systems that comply more with ecological than financial accounting principles is under way, but will require substantial development to meet the challenges of rising food needs and social aspirations.
