In Nepal, low quality and seasonal access to fish seed is an important restriction on the development of the aquaculture sector. Commercialisation of ﬁsh farming cannot progress rapidly in the absence of critical inputs and a regular supply of quality fish seed is an integral requirement for the transition of fish farming from a subsistence activity to a commercial enterprise. Participatory market chain approaches are a key tool for the social and economic improvement of farmers and market participants.
Feed is the most expensive component of an aquaculture enterprise. Successful cultured fish production requires optimisation of feeding practices to ensure the most economically eﬀective growth rates. Reducing feed costs for culture practices can be achieved by taking the advantage of restricted feeding strategies. Under a restricted feeding regime ﬁsh convert a greater portion of feed to body weight. Case studies of restricted feeding are presented for several species and the costs savings and other benefits are briefly discussed.
A Regional Proficiency Testing Program for Aquatic Animal Disease Diagnostic Laboratories in Asia-Pacific (the ‘regional PT program’) was developed in 2011 to strengthen diagnostic capability across Asia—a region that produces most of the world’s aquatic animal products. This capability was identified as a requirement to facilitate the sanitary safety of trade in aquatic animal products and to assist countries to improve accurate detection of potentially damaging trans-boundary diseases. The need for improved diagnostic capabilities across Asia was widely agreed and documented prior to developing the regional PT program, however few previous activities had made significant or lasting impacts at the regional level.
The regional PT program provided 41 laboratories across the Asia-Pacific with the opportunity to assess their diagnostic performance for 10 regionally significant aquatic animal pathogens, and to adapt or modify practices where necessary to improve. Through collective participation and improvement, regional capability to diagnose important aquatic animal pathogens has been strengthened.

This practical manual "Better management practices for seaweed farming" is produced by the Philippines national team under the ASEAN Foundation supported project "Strengthening capacity of small holder ASEAN aquaculture farmers for competitive and sustainable aquaculture" implemented by NACA in five ASEAN countries. The long-term objective of the project was to assist ASEAN small- scale aquaculture farmers improve their livelihoods by being competitive in markets and improving farm management practices to deliver quality and sustainably produced aquaculture products.
