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.

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.

FAO, NACA and the Thai Department of Fisheries convened a Regional Consultation Responsible Production and Use of Feed and Feed Ingredients for Sustainable Growth of Aquaculture in Asia-Pacific in Bangkok, 7-9 March 2017. The objective of the consultation was to review the current status of aquaculture feed production and use, demand and supply, sourcing of ingredients, government policies and institutional support, ongoing progress and development gaps. The meeting brought together government and private sector representatives.

The objective of this manual was to provide basic guidelines for the hatchery production of Pa Phia (Labeo chrysophekadion) fingerlings. It includes information on managing and spawning broodstock, genetic guidelines, egg incubation, hatching larviculture and fry rearing. Although the guidelines were specifically developed for production of Pa Phia at government hatcheries in the Lao PDR, they may be applied to other, related, species and could be adopted and commercialised by the private sector hatcheries

This Code of Practice is prepared to promote or ensure compliance to World Trade Organisation-Sanitary and Phytosanitary measures for the movement of live aquatic organisms in the Lower Mekong Basin. The goals of the Code are to achieve environmental protection and management, biodiversity conservation as well as prevention of spread of disease epizootics. Most of the points listed in this Code are based on the inputs of MRC Member Countries.
