A series of leaflets on better management practices for Penaeus monodon shrimp aquaculture in Vietnam. The leaflets are available in both Vietnamese and English and cover: Broodstock management for suppliers, postlarvae selection and transportation for seed traders, shrimp seed quality, pond preparation, good pond management, shrimp health management.

Our better-practice guidelines are an attempt to share lessons that are learnt from local practice or from research, with many more people within Asia-Pacific and to enable people, institutions and policy-makers to use new tools and mechanisms which support aquatic resources management in ways that benefit the livelihoods of people who are poor. This publication is also available in Bahasa Indonesia, Bengali, Hindi, Ilonggo, Khmer, Myanmar, Nepali, Oriya, Sinhala, Urdu and Vietnamese.

Self-help groups are a way to start working that helps to build up the social connections which people find useful in support of their livelihoods objectives, helping people to agree on things and to speak together, giving people a stronger voice in decision-making and in negotiating with more powerful forces. This publication is also available in Bahasa Indonesia, Bengali, Hindi, Ilonggo, Khmer, Myanmar, Nepali, Oriya, Sinhala, Urdu and Vietnamese.

The stories that fishers and farmers tell us about their lives can give us a deeper understanding of the realities of their experiences. They can help policy-makers to build an understanding of the aspirations and complex livelihood strategies of poor people and disadvantaged or marginalised groups. A consensus-building process is a way of providing a space where people can tell their stories, so that policies can be improved to better support poor people's needs.

These guidelines provide advice on producing fish seed in small-scale hatcheries. This publication is also available in Oriya.

‘Spawn’ is the name for the young fish about three days old that are available from hatcheries. Sometimes these young fish are also called hatchlings. The spawn of catla, rohu and mrigal is about 6-8 mm long. At this stage, the ‘yolk sac’ is absorbed, the mouth opened and the fins fully developed. Spawn are reared intensively, first to the ‘fry’ size and then to the ‘fingerling’ size. All the three stages are marketed and collectively called ‘seed’.

The “fast fingerling system” can produce advanced fingerlings about two months earlier than they are normally available from fish farms.  The farmer uses just one pond for continuous growing until fingerling size is reached, and fewer fish are stocked. A farmer with a small, seasonal pond can produce fingerlings in one month. These can then be sold for a high price because everyone wants fingerlings as early as possible.

The fingerling rearing pond, like the nursery pond, should be free from weeds and predators. Submerged weeds and predators are killed by mahua oilcake, which then acts as a good fertiliser. If there are no weeds, to kill predators and competitors quickly you can just add 100 kg of urea followed 24 hours later by 200 kg of fresh bleaching powder for a 1-ha area of a 1-m deep pond.

This is the proceedings of the workshop on Building capacity to combat impacts of aquatic invasive alien species and associated trans-boundary pathogens in ASEAN countries, held in Penang, Malaysia, on the 12th-16th July 2004. The workshop built on the recommendations from a 2002 workshop organised by the Global Invasive Species Program and a 2003 workshop of countries sharing the Mekong watershed, in promoting awareness, coordination mechanisms and information exchange systems and identifying management and risk mitigation measures.

In watersheds, medium irrigation projects can be useful for aquaculture even though these water bodies are many times larger than ponds, and are basically built for irrigation or water storage. However, the full potential of these water bodies is not yet realised. Net pens or cages can be used to rear fingerlings in such environments.
