This manual provides information on the farming of Macrobrachium rosenbergii. Many of the techniques described are also applicable to other species of freshwater prawns that are being cultured. The manual is not a scientific text but is intended to be a practical guide to in-hatchery and on-farm management. The target audience is therefore principally farmers and extension workers. However, it is also hoped that, like the previous manual on this topic, it will be useful for lecturers and students alike in universities and other institutes that provide training in aquaculture.

The farming of the freshwater prawn Macrobrachium rosenbergii has developed rapidly during recent years. Advances in techniques, and the huge expansion of world demand for this species, continue to stimulate the growth of a multi-million dollar industry. This landmark publication is a compendium of information on every aspect of the farming of M. rosenbergii. A comprehensive review of the status of freshwater prawn farming research, development and commercial practice, the book is intended to stimulate further advances in the knowledge and understanding of this important field. An extremely well-known and internationally-respected team of contributing authors have written cutting edge chapters covering all major aspects of the subject. Coverage includes biology, hatchery and grow-out culture systems, feeds and feeding, up-to-date information on the status of freshwater prawn farming around the world, post-harvest handling and processing, markets, and economics and business management. Further chapters are devoted to the culture of other prawn species, prawn capture fisheries and the sustainability of freshwater prawn culture. Contributions to the book have been brought together and edited by Michael New and Wagner Valenti, themselves widely known for their work in this area. The comprehensive information in Freshwater Prawn Culture will give an important commercial edge to anyone involved in the culture and trade of freshwater prawns. Readership should include prawn farm personnel, business managers and researchers, and invertebrate, freshwater and crustacean biologists. Copies of the book should be available on the shelves of all libraries in research establishments and universities where aquaculture and fisheries are studied and taught. Michael Bernard New, OBE is a Past-President of the World Aquaculture Society and President-Elect of the European Aquaculture Society; Wagner Cotroni Valenti is a Professor at the Aquaculture Center, São Paulo State University, Brazil.

A preliminary study of the protein requirements of the Malaysian giant freshwater prawn (Macrobrachium rosenbergii De Man) was conducted by dispensing pelleted diets consiting of varying levels of protein (10.7, 23.2, 37.5, 45.6, 49.2, 50.9, 55.4, 57.2 and 59.9%) in the form of fishmeal incorporated with other feed ingredients. Protein deficient and rich diets demonstrated growth rates that were not promising. An optimum weight gain and food conversion was observed in a diet amended with 47.3% carbohydrate. The amended carbohydrate levels in the diet also had an important bearing on the composition of the diet because it was the prime energy source. It was dound that food conversion values correlated very well with the growth rates of the experimental animals but not with that of protein efficiency ratio. [Author's abstract].

The administration of Butea superba in postlarvae Macrobrachium rosenbergii was conducted by B. superba mixing diet at the concentrations of 0, 0.05, 0.5 and 5% in 140 days of the experimental period revealed that all concentrations of B. superba mixed diet increased the weight and length of M . rosenbergii with no significant different in the first 4 weeks . On the contrary, the weight and length of M. rosenbergii reduced after that. At the end of the experiment, the weight, length, the size of the first abdominal segment and claw length of giant freshwater prawns were inhibited by the feed supplemented with and 5% B. superba. B. superba mixed diet did not increase the male ratio of theM. rosenbergii . All concentration of B. superba mixed diets decreased the ratio of male to female prawn. The number of ovigerous female was significantly decreased m concentration of 5% B. superba mixed diet. There were no significant different of survival rate among the treatments. The histological studies showed that the reproductive cells of mature M. rosenbergii were not affected B. superba concentration in the diet.
