A summary report of the proceedings of the Asian regional conference on carp hatchery and nursery technology held in Manila, Philippines, on 1-3 February 1984, sponsored by the Asian Development Bank and ICLARM.
This document outlines the specifications of a project for carp and mullet hatcheries, nurseries and collecting stations in Egypt.
This review is a compendium of most of the available biological and engineering knowledge relevant to the breeding and mass propagation of the Mugilidae species, particularly the grey mullet Mugil cephalus Linn.
This document represents the report and contributed papers from a workshop of the same name. The workshop was comprised of a group of 30 international experts and representatives of the environmental, fisheries and policy development agencies of the countries in the Volta Basin.
The availability and quality of fingerlings for stocking in aquaculture ponds have repeatedly been identified as a key constraint to the development of aquaculture in Africa. Government hatcheries have generally failed to achieve sustainability and the private sector is impeded by the lack of marketing information and appropriate technological assistance. At present, the main aquaculture species in the continent are Nile tilapia (Oreochromis niloticus) and the African sharptooth catfish (Clarias gariepinus).
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.
This document represents the report and contributed papers from the workshop Pioneering Fish Genetic Resource Management and Seed Dissemination Programmes for Africa: Adapting principles of selective breeding to the improvement of aquaculture in the Volta Basin, convened in Accra, Ghana 27-30 March 2007.
Production and supply of fish seed-stock are essential for the promotion of aquaculture. Traditional inland aquaculture was based on the collection of seed-stock from rivers and required the sorting and acclimatising of mixed species. Fine meshed nylon net cages ‘hapas’ have been used for this purpose for Chinese carps in China and in Bangladesh and India for Indian major carp for a long time. Hapa nursing of small fry to larger, more predator-resistant fingerlings has been the focus for intensification of aquaculture in North East Thailand and Lao PDR.
Rearing techniques of Indian, exotic and common carp seed in pens erected in reservoirs in Karnataka, Southern India are discussed. Constraints to seed production are also pointed out.
