After a preliminary section on the biology of freshwater prawns, the manual covers site selection for hatcheries, nurseries and grow-out facilities, and the management of the broodstock, hatchery, nursery and grow-out phases of rearing. Harvesting and post-harvest handling are also covered and there are some notes on marketing freshwater prawns.

2004年8月1日 · Hatchery development for freshwater prawns, based on the modified greenwater system, is making expansion of aquaculture in Vietnam’s Mekong Delta possible.

After a preliminary section on the biology of freshwater prawns, the manual covers site selection for hatcheries, nurseries and grow-out facilities, and the management of the broodstock, hatchery, nursery and grow-out phases of rearing. Harvesting and post-harvest handling are also covered and there are some notes on marketing freshwater prawns ...

The three phases of freshwater prawn culture are hatchery, nursery, and pond grow out. This publication provides detailed information on the design and operation of

research on the simplification of prawn hatchery operations, a second manual, “Prawn Hatchery Design and Operation,” was published in 1984. Since then, various hatchery techniques have been developed and prac­ ticed. This updated version presents the underlying principles and step-by- step instructions on prawn larval and postlarval rearing.

2018年2月3日 · This document summarizes freshwater prawn hatchery and nursery production. It describes the life cycle and biology of freshwater prawns, which are suitable for aquaculture due to their freshwater tolerance. Hatchery production involves broodstock holding, larval rearing, and nursery of post-larvae.
