    Nursery Rearing of Tiger Shrimp Post - Larvae in West Bengal, India -BOBP/WP/86 1993

    Ever since the shrimp farming industry took off in Bangladesh and West Bengal, shrimp fry collection has developed into a major income-generating activitiy for thousands of people living in the coastal belts of these areas. This paper describes trials with nursery rearing of the tiger shrimp (Penaeus monodon) in floating cages. They were carried out in Ramnagar, Medinipur District, West Bengal, India, from 1990 to 1992. The purpose was to introduce a technology by which the fry-catchers could augment their income by nursing the shrimp fry to a larger size, with higher market value, and be in a better bargaining position vis-a-vis the traders. The trials were undertaken by a group of shrimp fry-catchers in Ramnagar, with support from the Bay of Bengal Programme (BOBP). The subproject was sponsored by BOBP’s “Small-Scale Fisherfolk Communities in the Bay of Bengal”, (GCP/RAS/118/MUL), a project jointly funded by SIDA (Swedish International Development Agency) and DANIDA (Danish Int ernational Development Agency) and executed by FAO (Food and Agriculture Organization of the United Nations).

    The Shrimp Fry By-catch in West Bengal-BOBP/WP/88 1993
    Also available in:

    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.

    Pen Culture Of Shrimp By Fisherfolk:The BOBP Experience In Killai,Tamil Nadu, India - BOBP/WP/49 1987
    Also available in:
    No results found.

    This paper describes a shrimp pen culture pilot activity at KiIIai, Tamil Nadu, India under which selected fishermen operated small-sized shrimp pens, applying a technology package for KilIai conditions devised earlier during 21 months of technical trials by the small-scale fisheries project of the Bay of Bengal Programme (BOBP). The paper discusses the project’s socio-economic and technical approach, the problems faced during implementation, the results, and some recommendations for bett er profitability. A BOBP socio-economist and a senior administrative officer of the Tamil Nadu Directorate of Fisheries were responsible for the overall planning, implementation and monitoring. Technical inputs were provided by a BOBP aquaculture technologist. The field team at the project site consisted of two aquaculture technologists (biologists) of the TNDF, while a social worker engaged by BOBP liaised with fisherfolk and the technology team. This is the third paper on the KiIIai p roject. BOBP/WP/35 discussed the findings of 21 months of technical trials during 1982—84, while BOBP/WP/32 discussed a techno-economic end social feasibility study of shrimp pen culture, based on field surveys in the region conducted late 1983, after the technical trials.
