Technical publications

NACA publishes technical papers and manuals for a wide variety of farming systems and related environmental and social issues. Many of these provide guidance on better management practices with a view to improving crop outcomes and on-farm resource utilisation efficiency. By using inputs such as feed and power more efficiently, farmers can simultaneously improve their profitability and environmental performance.

Better-practice approaches for culture-based fisheries development in Asia

This manual provides guidelines for attaining better practices in culture-based fisheries, an emerging practice in rural areas in the Asian region. It deals with the principles of culture-based fishery practices, primarily based on relatively long-term experiences in Sri Lanka and Vietnam. It deals with the gross factors that are applicable to improving fish yields and therefore revenue; and sustaining culture based fisheries as a development activity in the long-term.

Better-practice guidelines: What are better practice guidelines?

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.

Better practice guidelines: Self-help groups

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.

Better practice guidelines: Information access surveys

An information access survey is a tool that identifies key issues about people and what information needs they have, what media sources are available, what strategies people use to get information and how cost effective they are. It also provides guidance on methods of communication that are useful for poor rural communities that use aquatic resources to improve their livelihoods. This document is also available in Bahasa Indonesia, Bengali, Hindi, Ilonggo, Khmer, Myanmar, Nepal, Oriya, Sinhala, Urdu and Vietnamese.

Better practice guidelines: Consensus-building process

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.

Better practice guidelines: Spawn production in hatcheries

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

Better practice guidelines: Fry production - nursing spawn

‘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’.

Better-practice guidelines: Fast fingerling production - nursing spawn in ponds

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.

Better practice guidelines: Fingerling production nursing fry in ponds

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.

The international seafood trade: Marine ornamentals trade in the Philippines and options for its poor stakeholders

This report provides insight into the status of the marine ornamental fish trade in the Philippines, including policy environment, collection, distribution channels, markets and constraints. The report also reviews the livelihoods of poor stakeholders in market chains including economic and financial aspects, natural and physical resources, livelihood patterns, social structures. The report provides recommendations for policy makers and stakeholders in improving the livelihoods of poor stakeholders in marine ornamental fish collection and market chains and resource management.
