Synopsis (short abstract) Shrimps and prawn culture has made significant advances during the last decade in many parts of the world. The incentive for such development was often the profit motive; the most favoured species were those which commanded the highest prices when sold as luxury foods. The demand for prawn in Thailand is way higher than supply plus the market price is 5–10 times higher than fish. Certainly such demand and benefits have provided sufficient stimulus to promote investment in prawn culture by the pr ivate sector. In order to help solve the problems which will occur after the rapid growth of prawn and shrimp culture, research on management techniques, disease and feed are necessary. Fundamental nutritional studies are required, prior to the development and commercial production of formulated feed. The nutritional requirements of shrimp have been intensively studied in Japan since 1971, and their results may be useful to our researches on shrimp nutrition and seed production. The purpose of our visit was therefore to concentrate on visiting establishments where the nutrition of marine and freshwater shrimp is being studied, and to discuss and exchange views on mutual problems and to improve our knowledge of shrimp nutrition and shrimp culture techniques generally. A list of the places visited and personnel met is given in Appendix I.

    This manual has been prepared as an easy-to-read guide to the choice, manufacture, storage and use of feed in small-scale aquaculture. It was written for fish and crustacean farmers, extension officers and university aquaculture students. Feeding increases the productivity of aquaculture farms but it constitutes the highest single cost item of running expenditure. Care in its use is therefore imperative. The manual attempts to answer the basic questions likely to be asked by those intending t o apply feed as part of a programme to intensify production. The main sections of the manual deal with the need to feed, feed composition, choice of feeds, feed manufacture, nutritional requirements, storage, feeding practice, record keeping and likely problems. Eighteen appendices cover a wide range of related topics including examples of feed formulae, feed machinery, feeding devices, simple tables of feed composition, binders, feeding tables and analytical methods.

    Freshwater prawn (Macrobrachium rosenbergil) farming is a rapidly expanding industry in Thailand. The production of both post-larvae and marketable prawn increased about 80 percent between 1979 and 1980. Currently the industry consists of 59 hatcheries and at least 455 farms utilizing approximately 2,346 rai (375 hectares) of land. Current hatchery production exceeds 25 million post-larvae per year with a potential production of over 100 million. The total production of marketable prawn in 1980 is estimated to be about 350 tons with a total retail value of nearly 70 million Baht ($3.5 million). Thailand is already a leader in terms of total land used for freshwater prawn production including Hawaii. Since culture technology is not expected to be a limiting factor for expansion, the future development of this industry depends mainly on its economic viability and the market potential for locally produced prawn. The economic viability of this industry was evaluated mainly based on the d ata collected from a field survey. The production efficiency of both hatchery and grow–out farm operations in Thailand is relatively low. The productivity per unit of Artemia (the most important food for juvenile prawn) used in the hatchery is only about half that in Hawaii, and the production of marketable prawn per unit of pond area is only one-third. However, despite the low productivities, all of the hatcheries and farms interviewed are currently making a good profit mainly because of the re latively low cost of inputs and the prevailing high price of prawn. The average rate of return to initial investment is high for both hatchery and grow-out farm operations. In most cases, the initial investment can be paid off within the second year of operation. However, this situation will change if the production exceeds the demand resulting in a lower price for prawn and hence lower profit.
