Inland Fisheries Resource Enhancement and Conservation in China

Inland aquatic ecosystems in China have been largely influenced by the large-scale economic activities and over-exploitation of aquatic resources. A wide range of fisheries resource enhancement and conservation activities have been carried out throughout China. This presentation reviews the history and practices and analyses the problems and insufficient in inland fisheries resource enhancement and conservation in China, and finally recommends some suggestions on technology and operation in order to sustain inland fisheries resources.

Inland Fisheries Resource Enhancement and Conservation in the Republic of Korea

The beginning of inland fisheries resource stock enhancement in the Republic of Korea dates back to the early 1970’s, when fishing pressure was relatively low, and its development was closely related to the overall trends in the inland fisheries production. The release of hatchery reared juveniles of inland fisheries resources has become an increasingly common practice for stock enhancement and conservation over the last three decades.

Inland Fisheries Resource Enhancement and Conservation in Myanmar

Myanmar's inland water resources are still largely in a pristine condition. Fish, consumed in fresh and many processed forms is an important component of the protein intake of the population; consumption is estimated at 43 kg capita per year in 2008-2009. Stock enhancement of inland waters in Myanmar has been conducted since 1967, initiated through a seed replenishing program to the natural water, such rivers, lake, dams even rice fields.

Inland Fisheries Resource Enhancement and Conservation in Nepal

The ecological and biophysical diversity existing in Nepal offers comparative advantages and opportunities to develop and restore inland fishery resources for livelihood enhancement and poverty alleviation of rural communities. Through good governance and proper legislative measures it is required to establish improved environmental protection. Efforts need to target beneficiaries such as disadvantaged and marginalized ethnic communities with training and awareness raising, appropriate legal instruments and infrastructure development needs proper mitigation in hydropower generation/irrigation projects.

Inland fishery resource enhancement and conservation in Thailand

The production from inland capture fisheries in Thailand is about 1 million tonnes per annum. Engineering the environment and fish stocking are the two major practices adopted, and closed-season fishing as well as control of fishing gears are used for conservation purposes. Fish stocking programs date back to the 1950s have been continuously conducted. This presentation provides a historical perspective on stock enhancement practices in Thailand since the 1950s.

Inland fisheries resource enhancement and conservation in Vietnam

Inland fisheries resource enhancement has been considered a major component of reservoir fisheries management since 1962. Multipurpose reservoir construction commenced about the 1960s for irrigation, hydropower generation and flood control. Reservoir fisheries are always a secondary or tertiary activity and are given low priority; however stocking has been considered a major component of reservoir fisheries management. This presentation reviews the history of and changes to stock enhancement practices in Vietnamese reservoirs since the 1960s.

Role of fish species introduction in reservoir fisheries in China: Case study on icefish

Fish species introduction has been a very important method of increasing fisheries production and economic output in China. A good example is the introduction of the icefish Neosalanx taihuensis into reservoirs and lakes in most areas of China. The present study aims to provide basic information on production, management strategies and biological characteristics in target reservoirs and lakes in China and guide introduction and management practices of the fish.

Status of Reservoir Fisheries in Five Asian Countries

Reservoir fish fauna, fisheries production and management methods, amongst others factors, differ widely. The differences in fish yield between reservoirs and/or between countries cannot be easily understood and are unlikely to be determined by individual parameters or characteristics. This volume takes stock of the current management practices with a view to utilising this knowledge to develop and or evolve appropriate national and or regional strategies for sustained development of reservoirs fisheries.
