About this Research Topic
Fishing pressure and global climate changes are affecting population size and structure, reproductive capacity and behaviour of wild fish. In contrast, the demand of fish for human consumption or feed manufacturing is steadily increasing. Aquaculture, i.e. the production of fish under controlled conditions, should provide an answer to this need and, therefore, domestication efforts have rapidly intensified for a number of species. However, fish in aquaculture often cannot display their normal swimming behavior due to excessive culture densities or insufficient flow streams in their holding facilities and, consequently, they may not experience the physiological benefits that swimming entitles their wild counterparts. This situation of reduced swimming exercise in captive fish has been suggested to result in fish with reduced fitness (both physical and reproductive), resulting in lower growth, survival and flesh (muscle) quality.
The aim of this topic is to provide up-to-date information on the swimming physiology of wild and farmed fish. Areas that will be covered under this topic include (1) migratory behavior, tracking and physiology of fish in the wild during their reproductive and/or feeding migrations, (2) molecular, biochemical, cellular and organismic physiological adaptations to swimming in fish and (3) development and implementation of technological approaches to study and stimulate fish swimming behavior both in the wild and in aquaculture.
