ProjectMarket Study of Tiger Shrimp Fry in West Bengal, India -BOBP/WP/87 1993
Also available in:
No results found.Rice-fish polyculture in bheries (enclosed paddyfields) has been a tradition in the West Bengal (India) delta. Fish are seeded naturally with the water let into the paddyfields. With the growing shrimp export market, shrimp culture in the bheries has proved economically attractive and the supply of tiger shrimp fry to the bheries is, now, a burgeoning business is West Bengal. The Bay of Bengal Programme (BOBP), at the request of the Government of West Bengal, studied the problems connected wi th the supply of tiger shrimp fry to the bheries. The problems were seen as a constraint to the development of the mainly export-oriented shrimp culture industry. BOBP looked into both natural collection and hatchery-reared supply of shrimp fry. It also helped the West Bengal Department of Fisheries to establish a small hatchery at Digha and it worked with some of the fry catchers of Medinipur District through a local NGO. The study of all these activities as well as the marketing process was seen as a step towards a better understanding of the existing tiger shrimp fry market and the fisherfolk involved in it. This, it was hoped, would lead to an elimination of some, if not all, the problems associated with the business. The BOBP study was undertaken under the ‘Small-scale Fisherfolk Communities’ project (GCP/RAS/l18/MUL). -
ProjectCage Nursery Rearing of Shrimp and Prawn Fry in Bangladesh - BOBP/WP/92 1994
Also available in:
No results found.The shrimp culture industry of Bangladesh depends on catches of the wild fry of tiger shrimp. Employment as fry-catchers has been generated for thousands of rural poor. But the marketing system is not well developed and high fry mortality occurs due to poor handling. The growing freshwater prawn farming sector, however, continues to demand increasing quantities of large juveniles. This report, based on field trials from 1990 to 1993, describes the results of cage nurseryculture trials with b oth tiger shrmip (Penaeus monodon) and giant freshwater prawn (Macrobrachium rosenbergii) fry. It was thought that fry-catchers would be able to increase their earnings through sales of nursed post-larvae and juveniles. The survival of nursed post-larvae in the distribution system would also be increased. However, it is unlikely that tiger shrimp fry nursing can be made profitable. On the other hand, cage culture of a combination of hatchery-reared post-larvae and wild-caught fry of the freshwat er prawn would be profitable. An NGO played an important role in the subproject by implementing technical trials and organizing and supporting participating fisherfolk groups. -
ProjectThe Shrimp Fry By-catch in West Bengal-BOBP/WP/88 1993
Also available in:
No results found.Culture of tiger shrimp has gained momentum over the last decade in many parts of the world due to its high export value. It has become a major foreign exchange earner in India, where West Bengal is the largest culture centre. In West Bengal, the basic input of tiger shrimp fry is met from the wild, with a large number of the rural poor engaged in shrimp fry-catching and trading in the 24 Parganas (N and S) and Medinipur Districts. However, the destruction of by-catch captured during fry-collect ion has been causing concern. This working paper, based on work done from October 1990 to September 1991 gives an overall picture of the shrimp fry by-catch by assessing quantitatively the seasonal and spatial variations in the species composition. By-catch is 64-99.4 percent of the total fry caught. The fry by-catch destroyed over a period of one year is estimated at 62 million - 2592 million. The study was carried out by the Central Institute of Brackishwater Aquaculture (CIBA) at its Rese arch Centre in Kakdwip, West Bengal. It was sponsored by the Bay of Bengal Programme (BOBP) of the Food and Agriculture Organization (FAO). Two field biologists were engaged by BOBP for sampling and data collection at three centres and the project was implemented under the supervision of CIBA scientists. The authors acknowledge the contributions of the following : Dr K. Alagarswami, Director, CIBA. Madras, for his guidance and keen interest in the investigations; A.V.P. Rao, Principal Scient ist, for monitoring the project and critically going through the manuscript; the field biologists, Rabi Sil and R.S. Halder, for collection of field data; and R.K. Chakraborti, Scientist (SG) for valuable suggestions.
