An ecological approach to mariculture of shrimp: Shrimp ranching fisheries.
MetadataShow full item record
Mariculture production in Japan has grown recently to nearly one million tons per year. Mariculture production in the shallow coastal waters of Japan mainly consists of eight species of finfish, six species of shellfish, and three species of algae. Kuruma shrimp culture techniques are highly developed. Nevertheless, only 1,800 tons of kuruma shrimp can be produced yearly. There is a demand for this species but culture grounds have become limited and there is not enough space to raise shrimp. In 1980, 600 million postlarvae were produced but one-half had to be released to the sea. The released shrimp that survived and grew have formed a new basis for the "Sea Ranching Fisheries" industry. The trial releases of postlarvae have proven that sea ranching of shrimp can be successful. To strengthen the foundation of sea ranching fisheries, there must be future research on ecological impact, as well as on physico-chemical water parameters. The life cycle, feeding habits, and predators of the shrimp must also be studied. Recent releases in Hamana-ko Lagoon, Shizuoka Prefecture, made by the research group of the Hamana-ko Substation of the Shizuoka Prefectural Fisheries Research Station have demonstrated the possibilities of sea ranching. This report discusses the research studies obtained at Hamana-ko Lagoon and the main problems of the use of this sea ranching method in mangrove swamp areas of Southeast Asia.

Technical ReportH Motoh - 1980 - Aquaculture Department, Southeast Asian Fisheries Development Center
Series: Technical report / SEAFDEC Aquaculture Department; 5This paper describes various types of shrimping and prawning gear and devices, most of which have been traditionally used in the Philippines, with some ecological notes. This study provides basic information on prawn culture and fry collection, which will be useful for private fishpond operators and workers.

Series: Asia-Pacific Marine Finfish Aquaculture Network; Publication No. 2005–01Recent improvements in hatchery production technology for high-value marine finfish species such as groupers have led to an increased interest in setting up hatcheries to produce fingerlings for aquaculture. Small-scale hatcheries make this technology available to poor people in developing countries. Capital costs for small-scale hatcheries are relatively low, and the profitability of these ventures ensures rapid payback of capital investment. This guide provides an outline of the requirements to establish a small-scale marine finfish hatchery, particularly the economic aspects. It is intended to provide sufficient information for potential investors to decide whether investment in such ventures is appropriate for them. The guide provides some basic technical information in order to give an indication of the level of technical expertise necessary to operate a small-scale marine finfish hatchery. However, it is not intended as a detailed technical guide to the operation of small-scale hatcheries. Additional resources, such as training courses in marine finfish hatchery production, are available and these are listed in this document. Development of small-scale hatcheries may be more appropriate where there are existing marine hatchery operations, e.g. for shrimp or milkfish. By definition, small-scale hatcheries do not have broodstock facilities, so a supply of fertilised eggs (usually from a larger hatchery) is essential. Access to fertilised eggs and experienced hatchery staff will limit the application of small-scale hatchery technology. Despite this, there is considerable potential for this technology to be widely adopted. This guide has been written by a team of experts in marine finfish aquaculture who have been involved in a multinational collaborative research project since 1999.
Traditional devices and gear for collecting fry of "sugpo" giant tiger prawn, Penaeus monodon in the Philippines H Motoh - 1980 - Aquaculture Department, Southeast Asian Fisheries Development Center
Series: Technical report / SEAFDEC Aquaculture Department; No. 4Eight typical devices and gears for catching the wild fry of the giant tiger prawn, Penaeus monodon, locally called sugpo are described and illustrated. There are three stationary ones vis. fry lure, fry filter net and set fry trap, and five mobile ones viz. scoop net, fry scare line, fry seine, triangular net, and fry bulldozer. These have been used traditionally in the Philippines. This design and manner of operation are adapted to the behaviors and habits of the sugpo fry such as clinging and incursion with the incoming tidal current in mangrove creeks or at the mouth of the brackish river.
