Abstract: | The inland aquatic ecosystem in China have been largely influenced by large-scale economic activities and over-exploitation
of aquatic resources. Fisheries resource enhancement and conservation activities have been carried out throughout China. These
activities include establishing artificial fish habitat and hatchery, releasing juvenile fish to rivers and lakes, forbidding
illegal fishing, and setting up natural reserves. The purpose of these activities is to restore the quantity of inland fisheries
resources, guarantee sustainable development of fisheries, maintain biological diversity and keep an ecological balance. These
activities, conducted with a variety of methods, numerous species, extensive water areas and large scale programs have played
an active role in fisheries resource enhancement and conservation. As a consequence the inland water environment has been
improved; the biological diversity and fish catch increased, and the social, ecological and economic benefits have been significantly
improved. However, problems such as inappropriate technology and nonstandard operations continue to affect fisheries resource
enhancement, conservation and ecological stability. This paper reviews the history and practice of inland fisheries resource
enhancement and conservation in China, analyzes the existing problems and deficiencies in the activities, and finally make
some recommendations on technology and procedures to sustain inland fisheries resources. |
