An overview of the current scientific knowledge available on climate change implications for fisheries and aquaculture is provided through three technical papers that were presented and discussed during the Expert Workshop on Climate Change Implications for Fisheries and Aquaculture (Rome, 7-9 April 2008). A summary of the workshop outcomes as well as key messages on impacts of climate change on aquatic ecosystems and on fisheries- and aquaculture-based livelihoods are provided in the introduction of this technical paper.

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.

The vegetation in Mahakam Delta is predominantly mangrove forest that consists of a pedada zone, Rizophora zone, transition zone, Nipa zone and nibung zone. Prior to 1980, mangrove vegetation in Mahakam Delta was pristine. Considerable changes in the extent of mangrove ecosystem occurred between 1990-2002 until 2001 when about 63% mangrove areas was deforested mainly due to conversion for shrimp ponds. Since 2002, partial efforts for restoration had been taken in mangrove replanting at some sites.

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.

This report provides an appraisal of the status of mangrove ecosystems and linkages with associated communities and their livelihoods. The report addresses ecosystem health and function, the livelihoods of poor people, goods and services and gender issues. The major causes of impacts to mangrove forest and related aquatic resources are considered along with community perceptions of trends in natural resource quantity, economy, social relations and conflicts. Relevant policies and laws are briefly reviewed.
