This report, the 36th in the series, contains information about the aquatic animal health status of fifteen states in the Asia-Pacific region. The foreword discusses recent activities in support of aquatic animal health in the region.

This report describes a training course on grouper hatchery protocols that was held in Indonesia in 2006. A total of 20 participants from 13 countries attended the training course which was hosted by the Brackishwater Aquaculture Development Centre, Situbondo. Participants came from Australia, Hong Kong, Indonesia, India, Malaysia, Maldives, Myanmar, Philippines, Qatar, Saudi Arabia, Singapore, Thailand and Vietnam.

The Marine Products Export Development Authority (MPEDA) and the Network of Aquaculture Centres in Asia-Pacific (NACA) jointly hosted a special session on Better Management Practices (BMPs) at the 3rd INDAQUA 2007, 11-13 January 2007, Chennai, India. The presentations made in the session include i) International principles for responsible shrimp farming; ii) MPEDA-NACA Village demonstration programme, India; Aquaculture rehabilitation and implementation of BMPs in tsunami affected Aceh, Indonesia; and Markets, certification and traceability and small-scale farmers.

Shrimp Health Management brochures provide better management practices in a reader friendly format. These brochures were prepared as extension materials through the village based demonstration programme by the Marine Products Export Development Authority of India and NACA. The programme continues building success and involved a total of 29 villages and 29 Aquaclubs in five Indian states (Andhra Pradesh, Tamilnadu, Orissa, Gujarat, and Karnataka) in 2006.

This report, the 34th in the series, contains information about the aquatic animal health status of fourteen states in the Asia-Pacific region. The foreword discusses efforts towards international harmonisation in aquatic animal health standards.

Two in-country projects, in India and Vietnam, have provided good examples of translating the International Principles on Responsible Shrimp Farming into specific better management practices (BMPs) adapted to local farming conditions and ensuring their implementation by relevant stakeholders. The results range from improved yields, less impact on the environment, wholesome products, and better relations among players in the market chain. In short, the implementation of the BMPs has provided benefits to the farmers, environment and society.

This report examines the role mariculture could play in reducing poverty and providing alternative livelihood opportunities for people living in coastal areas. This includes a review of the current status of coastal poverty, coastal livelihoods and vulnerabilities within the Asia-Pacific region and the experiences and examples of sustainable economic development through mariculture. This review then identifies key follow-up actions and recommends strategies for future pro-poor mariculture development.

This report, the 32nd in the series, contains information about the aquatic animal health status of fifteen states in the Asia-Pacific region. The foreword discusses regional cooperation for promotion of aquatic animal health management.

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.

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.
