Book (stand-alone)Introductions and movement of Penaeus vannamei and Penaeus stylirostris in Asia and the Pacific 2004
Also available in:
No results found.Both Penaeus vannamei and Penaeus stylirostris originate on the western Pacific coast of Latin America. They were introduced in the early 1970s to the Pacific Islands, where research was conducted into breeding and their potential for aquaculture. Beginning in 1996, P. vannamei was introduced into Asia on a commercial scale. The main reason behind the importation was the perceived poor performance, slow growth rate and disease susceptibility of the major indigenous cultured shrimp species, P. ch inensis in China and P. monodon elsewhere in Asia. However, there remain many unanswered questions regarding the possible effects of introduced species. This report has attempted to gather all the currently available data on the extent of P. vannamei and P. stylirostris importation and culture in Asia, their advantages and disadvantages and potential problems. It offers recommendations, for both governments and the private sector, aimed at controlling the importation, testing and culture of thes e species. -
Book (series)FAO species catalogue. Vol. 1 Shrimps and prawns of the world. An annotated catalogue of species of interest to fisheries 1980
Also available in:
No results found.The present publication is intended to provide as complete an enumeration as possible species of Decapoda Natantia (shrimps and prawns) that are of interest to fisheries. It actually is the third edition of a list, the first draft of which was prepared by Mr. H. Rosa, Jr. and circulated in April 1964 as part of the paper "Note on the FAO Scientific Meeting on the Biology of Shrimps and Prawns with a preliminary List of their Species of Economic Value and Information on their Distribution" which formed FAO Fish.Circ., (14). The second draft was published in 1965 by L.B. Holthuis and H. Rosa, Jr. under the title "List of Species of Shrimps and Prawns of Economic Value" as FAO Fish.Tech.Pap., (52). During the 1967 FAO World Scientific Conference on the Biology of Shrimps and Prawns held in Mexico City, the present author was charged with the revision and expansion of this list. The present publication is now presented in fulfillment of that request. The actual catalogue in its present f orm was-completed by the author in 1978. The editorial work as well as the preparation of the additional section "List of Species by Major Marine Fishing Areas" and the indices of Latin and vernacular species names were carried out in the Fishery Resources and Environment Division of FAO, under the supervision of W. Fischer. -

Establishment of a Network of Aquaculture Centres in Asia
1984Also available in:
No results found.Marine shrimp farming is a century-old practice in many Asian countries. Until a decade ago, this commodity was still generally considered as secondary crop in traditional fish farming practices. in Thailand, Malaysia, Singapore and India, shrimp fry were accidentally trapped in the salt beds and paddy fields around estuarine areas, whereas in Indonesia and the Philippines, marine shrimps enter milkfish ponds during tidal exchange. Only recently, due to higher income derived from the harvest of marine shrimp than the principal crop, the farmers eventually converted these fields into shrimp farms. In traditional shrimp farming, sources of wild shrimp fry are either through natural entrance during tidal water exchange or intentionally gathered from the wild and stocked directly in the ponds. Production is dependent on the seasonal abundance of wild fry which fluctuates widely from year to year. In addition, water depth in rearing pond is generally shallow which often leads to extreme f luctuations of water temperature and salinity causing large scale mortality. Predation by carnivorous fishes gaining entrance in the ponds also accounted for considerable loss of shrimps. Production relies almost entirely on natural pond fertility since fertilizers and feeds are not generally used. Consequently, yields are low in the range of 100 – 300 kg/ha/year. Gradually, over the years, some improvements in the traditional methods of culturing shrimp have evolved. For instance, the stockin g density could be increased with the aid of water pump and increasing water depth in the pond which favors shrimp growth since temperature can be maintained and mortality reduced. Production can also be raised by increasing stocking density in pond with the fry collected from the wild. However, supply of seed from the wild is still inconsistent and insufficient that large scale development of the industry cannot be realized.
