This technical paper provides an analysis of the economic implications of, and the reasons for, adopting various feeding practices for different fish species and aquaculture systems in Asia. The systems studied include extensive/traditional, semi-intensive and intensive farms for a number of different species including sutchi and pangasiid catfishes (Bangladesh and Viet Nam), hybrid catfish (Thailand), carp polyculture (India and China), prawn and milkfish polyculture (the Philippines).

IDRC and NACA convened a workshop to identify the main research issues and needs to sustain Asian aquaculture into the first quarter of the 21st century, and also to bring them to the notice of relevant planners, managers and policy makers, and potential donors. The workshop was held in Rayong, Thailand from 4-7 June 2007. This report contains the issues papers drafted in preparation for the meeting and a summary of the discussions.

This report describes a training course on marine finfish hatchery protocols, which was convened at the Karabi Coastal Fisheries Research and Development Center, Thailand at the request of the Secretariat of the Pacific Community. The main goal of the training was to carry out hands-on practical work in finfish hatchery techniques, with an emphasis on grouper. This work involved spawning induction, incubation and larval rearing until day 12.

The 5th Regional Grouper Hatchery Training Course was another success with all participants is pleased with the overall training activities and field trips. A total of 17 participants from eight countries attended the training course which was hosted by the Brackishwater Aquaculture Development Centre, Situbondo, Indonesia. Participants were able to involve in the broodstock activities for giant grouper, in additional to the tiger and humpback groupers, and attended field trips to backyard hatcheries and export facilities.

These standard operating procedures were developed to reduce the risk of spread of trans-boundary disease of aquatic animals through the movement of live food fish. The procedures are a set of documents for health certification and quarantine measures to be used by competent authorities in trade among ASEAN member countries. The procedures recognise the existing variation in capacity between ASEAN members and have been designed so that they can be implemented across varying policy and legal frameworks.

This training manual (in Thai language) provides guidance in marine finfish cage aquacutlure techniques. It is geared towards giving small-scale farmers a solid technical grounding that will enable them to improve their farm productivity and reduce losses through understanding of markets and economic factors, better farm siting. and improved feeding, handling and stock management practices. This knowledge will help the trainees and other fish farmers to improve their productivity and profitability while also reducing their risk profile.
