Policy brief: Livelihoods approaches in fisheries and aquaculture

In the Asia-Pacific region national government support to aquatic resources management has tended to focus mainly on research and technology development. However, as we accept an increasingly important role for national fisheries administrations in poverty alleviation, we need to consider the choices that people make, the resources they can command and the circumstances in which they can be woven into supporting livelihoods. This means understanding more about people's livelihoods, resources, context, vulnerabilities and objectives.

Policy brief: Building consensus

Consensus-building techniques are particularly appropriate when decision-making is required in a political or emotional environment, or when the decisions affect strong factions with opposing preferences. It can work formally or informally, in large or small group contexts, assisting in reaching agreement on policy change proposals, involving people that are recipients of policy, implementers of policy, shapers of policy and policy makers in defined roles with a process to give people a voice.

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.

Policy brief: Development and management of aquaculture-based fisheries enhancements

This policy brief aims to promote better management of aquaculture-based fisheries enhancements (stocking of hatchery fish to improve fisheries) through integrated analysis of enhancement systems and quantitative assessment of management practices through use of the EnhanceFish decision tool.

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.

Better practice guidelines: Fingerling production nursing spawn and fry in pens

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.

Better practice guidelines: Advanced fingerling production in seasonal ponds

It is best to stock advanced fingerlings in large ponds, tanks, and in both small and large reservoirs, since they can better escape predators and competitors. Seasonal ponds, often 0.10-0.15 ha and 1.5-1.8 m deep can be used as rearing ponds for raising advanced fingerlings. Low water levels at the end of the season will make netting and harvesting easy.
