ProjectImprovement of Large-Mesh Driftnets for Small-Scale Fisheries in Bangladesh - BOBP/WP/5 1980
Also available in:
No results found.Driftnets account for nearly 30 per cent of the total marine catch in Bangladesh. With the polyamide (PA) or nylon twine used for constructing the nets getting scarcer and costlier, the driftnetters tend to carry less and less gear, affecting fish catch and incomes. It is therefore desirable to devise ways to ensure that driftnets cost less and/or produce more. This was the rationale for an experimental project conducted during the 1979/80 winter season. The boats used three kinds of fishing gear-the traditional large-mesh driftnets (45 ply), modified nets of thinner netting twine (27 ply) and nets of polyethylene material. Details of fish catch were recorded daily for thethree types of nets with the assistance of extension workers from the Kalidaha fishing project. A comparative study of the data obtained reveals that nylon nets of thinner twine size, which cost approximately 40% less than the traditional nets, caught about 40% more fish. Thus the thinner twine n ets are clearly preferable to the traditional. Following from these results, a promotional effort to extend the merits of this net is recommended, with the Bay of Bengal Programme assisting in the effort. As for the nets of polyethylene netting material, they also caught 45% more fish tha n the traditional nets, but sustained greater damages. Further studies are recommended on the efficacy of polyethylene netting material and on the optimum mesh sizes for large-mesh driftnets. Stud y tours of large-mesh driftnet fisheries in other countries are also recommended for Bangladesh national officers. -
ProjectTrials In Bangladesh Of Large-Mesh Driftnets Of Light Construction - BOBP/WP/12 1981
Also available in:
No results found.This document is the second report of a fishing gear improvement project in Bangladesh. It describes the rationale, the mechanics and the findings of experiments with large-mesh driftnets of thin twine conducted near Chittagong from October 1980 to February 1981. The experiments were carried out in cooperation with the Kalidaha Fishing Projectof CARITAS, a social service agency. In a parallel activity, experimental thin-twine large-mesh driftnets were also tried out by private fishermen in commercial fishing operations along with their own traditional fishing gear. The experiments yielded the finding that driftnets of thinner twine, which are about 40% cheaper than the traditional nets, also catch more fish than the traditional nets. Experiments were also carried out by BOBP with driftnets of different mesh sizes in cooperation with the Kalidaha Fishing Project. Here the conclusion was that large-mesh sizes are more effective than the smaller. The Ministry of Fisher ies and Livestock, Bangladesh, participated in the fishing gear improvement project as a cooperating agency. The project is an activity of the Programme for the Development of Small-Scale Fisheries in the Bay of Bengal, referred to in brief as the Bay of Bengal Programme. This is a regional FAO programme that seeks to develop and demonstrate appropriate technologies and methodologies in many areas of small-scale fisheries such as fishing craft, fishing gear, fishing methods and utilization and c oastal aquaculture. The Programmes goals are to improve the conditions of small-scale fisherfolk and the supply of fish from the small-scale sector in five countries that border the Bay of Bengal — Bangladesh, India, Malaysia, Sri Lanka and Thailand. -
ProjectBoatbuilding Materials for Small-Scale Fisheries in India - BOBP/WP/9 1980
Also available in:
No results found.This paper summaries a study on the availability and prices of materials used to construct the hulls of fishing craft for the important small-scale fisheries of the East Coast of India. The paper should be of interest to development planners, legislators and administrators. Builders of fishing craft, suppliers of materials, and owners and prospective owners of fishing craft may also find useful the information on trends in prices and availability of boatbuilding materials and the possibilities o f alternative materials. The study covered the following boatbuilding materials: timber for kattumarams and boats; fibre-reinforced plastics; ferrocement; steel; and aluminium, which is used forsheathing wooden hulls and is also a construction material in its own right. The study was carried out by Matsyasagar Consultancy Services Private Limited under contract to the Programme for the Development of Small-Scale Fisheries in the Bay of Bengal, GCP/RAS/040/SWE (usually abbreviated to th e Bay of Bengal Programme). The Programme is executed by the Food and Agriculture Organisation of the United Nations (FAO) and funded by the Swedish International Development Authority (SIDA). The main aims of the Bay of Bengal Programme are to develop and demonstrate technologies by which the conditions of small-scale fishermen and the supply of fish from the small-scale sector may be improved, in five of the countries bordering the Bay of Bengal — Bangladesh, India, Malaysia, Sri Lanka an d Thailand.
