Quarterly Aquatic Animal Disease Report Q2 2015

Published: 7/12/2015 | 1639 views

The regional Quarterly Aquatic Animal Disease (QAAD) reporting system has been implemented since the second quarter of 1998 and continues to provide a useful mechanism for aquatic animal disease information sharing amongst 21 participating governments in the Asia-Pacific region. The QAAD reporting system is a joint activity between NACA, FAO and OIE Regional Representation (Tokyo). The 2015/2 QAAD report, 68th in the series, includes disease information from 13 governments. This issue's foreword discusses harmonisation of aquaculture certification in the ASEAN.

Perspectives on culture-based fisheries developments in Asia

This book is the proceedings of the “Regional Consultation on Culture-Based Fisheries Development in Asia”, held in Siem Reap, Cambodia, 21-23rd of October 2014, under the auspices of the Australian Centre for International Agricultural Research (ACIAR), the Mekong River Commission (MRC) and the Network of Aquaculture Centres in Asia-Pacific (NACA). The consultation was jointly organised by NACA and the Fisheries Administration of the Royal Government of Cambodia.

Food and nutritional security remains problematic in many developing countries.  There are many initiatives underway which are designed to increase food supply, employment and income opportunities, most of which require considerable capital inputs (for instance cropping, livestock production and aquaculture). Often overlooked, are the opportunities to produce more food from the natural productive ecology of lakes and forests. Culture-based fisheries are one example of a relatively simple and low cost technology which can deliver nutritional and economic benefits to communities which often have few livelihood options.

Culture-based fisheries are based in lakes and reservoirs, where fish populations are supplemented by hatchery-produced fingerlings. The stocked fish may breed naturally in the lakes, or they may be species which are desirable but which do not breed in the still-water environments. Fish growth is driven by the natural productivity of the water bodies. Generally, local communities have ownership of the fish, with the benefits shared or used for communal purposes. However, there are other options for management and ownership depending on local needs, cultural arrangements and other uses of the water.

Research and development of culture-based fisheries has been a major endeavour for NACA and ACIAR since the mid-1990s. This has involved projects in Sri Lanka, Indonesia, Vietnam, Lao PDR and Cambodia, the results of which have been reported in previous publications, as noted below. In this volume, we bring together an update from research conducted in those countries and others. We trust the information will foster further development and spread of culture-based fisheries in Asia and beyond, and in doing so, bring livelihood and nutritional benefits to otherwise resource-poor communities.

Culture-based fisheries in lakes of the Yangtze River basin, China, with special reference to stocking of mandarin fish and Chinese mitten crab

Author(s): Wang, Q., Liu, J., Li, Z., Zhang, T. | Published: 12/5/2015 | 1265 views

Lakes amount to 15% of the total freshwater surface area in China and are important for land-based fisheries. More than 10 species are stocked into lakes to increase production and/or improve water quality. The most common species stocked are the Chinese major carps, i.e. silver carp, bighead carp, grass carp and black carp. In recent years, increasing amount of high valued species such as mandarin fish, mitten crab, yellow catfish and culters were stocked. However, the stocking of mandarin fish and mitten crab perhaps are the most successful because stock enhancement of these two species has been systematically conducted.

In this paper, the culture-based fisheries in lakes are presented, with special reference to mandarin fish and mitten crab stocking in lakes in China. The stocking rate of mandarin fish is determined by food consumption rates, which are mainly related to water temperature and fish size, and prey fish productivity. A bioenergetics model of mandarin fish was established to predict the growth and consumption of prey fish in stocked lakes. Impacts of stocked mandarin fish on wild mandarin fish populations are also dealt with. The stocking model of mitten crab in of culture-based fisheries was also determined based on biomass of macrophyte coverage, benthos biomass and ratio of Secchi depth to mean water depth in lakes.

Since increasing attention is being paid to eutrophication of lakes in China, land-based fisheries development now prioritise maintaining integrity of water quality and biodiversity conservation. Integrated stocking of different species and lakes fisheries management are also addressed.
