Farming freshwater prawns: a manual for the culture of the giant river prawn (Macrobrachium rosenbergii).
This new manual, which replaces an earlier manual first issued in 1982, is an up-to-date practical guide to the farming of Macrobrachium rosenbergii. Many of the techniques described are also applicable to the culture of other species of freshwater prawns. The principal target audience is farmers and extension workers but it is also hoped that it will be useful for aquaculture lecturers and students. 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 reference and bibliography section contains a list of relevant reviews, as well as other (mainly FAO) manuals on general aquaculture themes, such as water and soil management, topography, pond construction and simple economics. The management principles described are illustrated by photographs and drawings. The manual contains annexes on specific topics such as the production of larval feeds, size variation and stock estimation. The final annex is a glossary that lists not only the terms used in the manual itself but also those that may be found in other documents.
