Also available in:
No results found.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. -

No results found.The Workshop on Bycatch, Particularly in Prawn Fisheries, and on the Implementation of an Ecosystem Approach to Fisheries Management was attended by participants from Kenya, Madagascar, Maldives, Mauritius, Mozambique, Seychelles, South Africa, Somalia and the United Republic of Tanzania. The workshop was also supported by resource persons from Italy, Nigeria and the United States of America. The workshop received from the countries national reports and reviews concerning bycatch, se a turtle distribution, critical habitats, main sources of natural and man-induced mortality and conservation efforts. The use of turtle excluding devices (TEDs) and interactions between sea turtles and fisheries in the shrimp trawling was discussed. It was concluded that two workshops about turtle and fisheries should be set up, the first for collecting data on turtle occurrence and mortality and the second for presenting these results to managers, fisheries associations and industry in an attempt to find the best solutions and exchange knowledge. Information about the countries implementation of the ecosystem approach to fisheries (EAF) management effort was reported. Two different methods of identifying ecosystem approach to fisheries issues and risk analysis in order to prioritize the issues were presented and tested. Obstacles on implementing the EAF were considered by the workshop and, as a way forward, it was concluded that a risk assessment for sustainabl e fisheries (RASF) approach should be applied in order to implement EAF in the region. This could be done in national case studies. -
