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.

Everyone wants advanced fingerlings as early after the rains as possible. They fetch a good price and make marketable fish production possible in seasonal ponds. One way to produce early season advanced fingerlings is to grow them in perennial ponds and store them at high density with minimal feeding for the coming year. Whe such "stunted" fingerlings are stocked into ponds with good feed they grow fast and can be marketed in about 6-8 months.

Common carp is a foreign fish and there are several varieties. The variety used in Western Orissa is the fully scaled carp, which suits the tropical climate. Common carp lives and feeds near the pond bottom and can be grown with the Indian major carps, catla, rohu and mrigal as a 'polyculture' (which means growing many different types of fish together). It can also be grown alone, as a 'monoculture' in rice fields with high dykes that retain water.

These guidelines provide advice on producing fish seed of the Indian major carps in hapas within ponds to improve survival.

The Asia Regional Advisory Group on Aquatic Animal Health meets annually to discuss regional health issues including emerging disease threats. This report includes a review of regional disease status circa 2005, global and regional disease reporting arrangements, global issues and standards, progress in implementation of the the Regional Technical Guidelines on Health management for the Responsible Movement of Live Aquatic Animals, identification and designation of regional aquatic animal health resources and regional and international cooperation.

Self-recruiting species are defined as aquatic animals that can be harvested from farmer managed aquatic systems without regular stocking. This may include indigenous or introduced, small or larger species. Identified self-recruiting species in the Red River Delta includes exotic species (tilapia), large (snakehead, walking catfish and river catfish) and small (Anabas and Carassius auratus) indigenous fish species and non-fish species (freshwater shrimp and crabs).

This is the report of an inception workshop for the Mekong Giant Catfish Working Group. The Mekong giant catfish Pangasianodon gigas is listed as critically endangered in the 2003 IUCN Red List. The purpose of the workshop was to exchange information on the current state of the Mekong giant catfish and the relevant conservation and research activities of key organisations, and to establish a joint planning process aimed at developing an overarching conservation strategy for the Mekong giant catfish.
