Review on Environmental Enrichment for Aquatic Organisms

Abstract:

With the development of fishery technology and people's improving living standards, the demand for aquatic organisms has gradually increased. Whether in terms of economic value, ornamental value and educational significance, aquatic organisms have gradually become an indispensable part of our lives. However, aquatic organisms especially fish still have a low level of welfare in the process of the breeding, transportation and display. Finding a suitable method to solve the problems of low welfare of aquatic organism has become an important issue for improving aquatic organism welfare. As one of the technical means to improve the welfare of captive animals, environmental enrichment can increase the living conditions and welfare of captive animals by adding some stimulating factors to the captive environment, so as to make the captive animals have normal psychological and physiological health and show their natural behaviors. At present, compared with foreign countries, domestic researches on environment enrichment of aquatic organisms is still in its infancy. Using environmental enrichment technology to improve the living conditions, ensure and enhance the level of welfare of aquatic organisms has become a research hotspot. Therefore, based on the review of the research progress and application of environmental enrichment technology in aquatic organisms at home and abroad, this paper divided the environmental enrichment technology of the aquatic organisms into four categories, discussed the existing problems of environmental enrichment technology and put forward some suggestions, in order to provide more scheme reference and theoretical basis for environmental enrichment technology of aquatic organisms.
