Pen fish culture in reservoirs: an alternative to land based nurseries

An experiment to rear carp seed was conducted in Tamil Nadu, India during October 2001 to April 2002 as a part of an ambitious programme aimed at standardization of pen fish rearing technology for production of stocking material of desired size at a lower cost. The experiment used six pens erected using locally available materials in the exposed marginal area of an existing reservoir.

An organic matter and nitrogen dynamics model for the ecological analysis of integrated aquaculture/agriculture systems: II model evaluation and application

The performance of a model developed to simulate organic matter and nitrogen dynamics in integrated aquaculture/agriculture systems was evaluated using sensitivity analysis and model verification procedures with data from three sites.

Most significant change (MSC)

MSC was developed by Rick Davies in the early 1990’s, primarily to address the problem of ‘how to summarise & report progress when there is a diversity of activities, not all known in advance, let alone their outcomes and a need to respect people’s judgements of what is important to them.’

Linking small-scale fisheries and aquaculture to household nutritional security: an overview

Small-scale fisheries and aquaculture have been recognized as important opportunities to enhance household food security in developing countries. While interventions aiming at promoting these activities reveal many positive effects, their direct and indirect impacts on nutritional status have not yet been fully documented. The objective of this paper is to identify more specifically the potential pathways that exist between fish-related livelihoods (small-scale fisheries, fish farming) and household nutritional security.

Lessons from the breeding program on common carp in Hungary

Common carp is one of the most important cultured freshwater fish species in the world. Its production in freshwater areas is the second largest in Europe after rainbow trout. Common carp production in Europe was 146,845 t in 2004 (FAO Fishstat Plus 2006). Common carp production is concentrated mainly in Central and Eastern Europe. In Hungary, common carp has been traditionally cultured in earthen ponds since the late 19th century, following the sharp drop in catches from natural waters, due to the regulation of main river systems.

The introduction of exotic fish in Sri Lanka with special reference to tilapia.

Introductions of exotic finfish between 1948 and 1953 are reported in this paper, with a brief reference to earlier and later introductions. Exotic fish were introduced principally to develop the potential for aquaculture in fresh and brackish waters in order to increase the availability of fish for rural communities through the biological control of aquatic vegetation. The algal feeding tilapia (Sarotherodon mossambicus) has created a new food industry in inland and brackishwaters.

Integration of aquaculture and agriculture: a route to sustainable farming systems

The integration of agriculture and aquaculture as a means of intensifying resource use and improving the productivity of many current farming practices in Southeast Asian and African countries is discussed. A brief account is given of work undertaken by ICLARM in Malawi and India regarding the improved use of marginal lands to integrate crops, vegetables, trees, livestock and fish, outlining also the various problems involved in the extension of such integrated fish farming systems.
