Hatchery and nursery

This report describes a training course on marine finfish hatchery protocols, which was convened at the Karabi Coastal Fisheries Research and Development Center, Thailand at the request of the Secretariat of the Pacific Community. The main goal of the training was to carry out hands-on practical work in finfish hatchery techniques, with an emphasis on grouper. This work involved spawning induction, incubation and larval rearing until day 12.

The 5th Regional Grouper Hatchery Training Course was another success with all participants is pleased with the overall training activities and field trips. A total of 17 participants from eight countries attended the training course which was hosted by the Brackishwater Aquaculture Development Centre, Situbondo, Indonesia. Participants were able to involve in the broodstock activities for giant grouper, in additional to the tiger and humpback groupers, and attended field trips to backyard hatcheries and export facilities.

The National Aquaculture Development Authority of Sri Lanka (NAQDA) took several steps to regularise collectors of Penaeus monodon under the restructuring programme of the shrimp aquaculture industry in Sri Lanka. Regularisation of broodstock collectors is very imperative mitigate transmission of white spot disease. NAQDA developed these practices in consultation with the Department of Fisheries and Aquatic Resources, shrimp hatchery owners, broodstock suppliers, NARA, Wayamba environmental authority, Sri Lanka aquaculture development alliance and the consortium for shrimp aquaculture development.

Participants came from Australia, Hong Kong, Indonesia, India, Malaysia, Maldives, Myanmar, Philippines, Qatar, Saudi Arabia, Singapore, Thailand and Vietnam.

L'élevage de la crevette est l’un des secteurs d'aquaculture le plus en essor dans beaucoup de régions du monde, il est également l’un des plus controversés. L'expansion rapide de ce secteur a généré, certes, des sources de revenus pour plusieurs pays, mais elle a été accompagnée par une préoccupation croissante sur les impacts environnemental et social. Les Principes Internationaux pour l'Elevage Responsable de la Crevette fournissent la base sur laquelle les parties prenantes peuvent collaborer pour un développement plus durable de l'élevage de crevette.

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.

Shrimp farming is one of the fastest growing aquaculture sectors in many parts of the world and also one of the most controversial. Rapid expansion of this sector generated income fo many countries, but has been accompanied by rising concerns over environmental and social impacts. The International Principles for Responsible Shrimp Farming provide the basis upon which stakeholders can collaborate for a more sustainable development of shrimp farming.

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’.
