Cataloging Marine Fisheries Resources of Bangladesh

Dr. Md. Shahadat Hossain
Professor
Institute of Marine Science & Fisheries, Chittagong University

Abstract/ Executive Summary:

This project mainly aims at updating and cataloguing of fisheries species of the Bay of Bengal, Bangladesh. A total 359 bony fishes along with records of some new species with colour illustrations presented in taxonomic key book. Taxonomic studies were made on the basis of morphological characters of the collected specimens. Identification and other information about the species were done with the help of available literatures. Attempts were made to provide valid scientific name of all the genera, and species were listed in accordance with the rules and principles as set forth in the international code, known vernacular names were also mentioned. The study results would help support formulating effective fisheries management plans and policies.

Keywords: Marine Fish, Bay of Bengal, Taxonomy

Location: Bangladesh

Start Date:

End Date:

Program Area: Variety and Species

Commodity: Marine fish

Objectives:

To create an up-to-date and complete species catalog of the fish species
To assess the temporal and spatial fisheries diversity in the marine ecosystem of Bangladesh
To facilitate continued research and assessment at MFTS and IMSF through creating/improving fisheries museum and geoinformatics laboratory

Methodology:

A detailed survey was conducted in and around of landing center/ local market/fishing boat at Cox’s Bazar (Technaf, St. Martin’s, Moheshkhali, Chakoria, Kutubdia) and Chittagong (Anawara, Sitakunda) to find out the available fish species, their abundance, season, etc. Adult species were collected 3-5 specimens per species in fresh and whole. For large size fish, the young sample was collected. After sample collection Photography Morphometric and meristics data were collected. Taxonomic studies were made on the basis of above mentioned morphological characters of the collected specimens. For sampling, coastal and marine fishing areas were divided into 8 zones for spatial diversity analysis of each species. These were 1. Sundarban and adjacent coastal waters 2. Barishal-Patuakhali coastal waters and river inlets 3. Meghna estuary and river inlets 4. Chittagong Cox’s Bazar coastal waters 5. Shallow shelf sea (up to about 40m depth) 6. Commercial fishing zone (from 40m to about 90m depth 7.Deeper shelf waters (up to 100m depth) 8. Deep waters (beyond 100m depth).

Funding Source:

1. Government

Budget: 900,000

Total Budget (Tk.) : NaN

Achievement/Findings:

Fish samples from the selected locations have been collected following the protocol. Photography, morphometric and meristics database of the 359 species have been developed. Common length 2-3 m with maximum 4 m, common weight 20-30 kg with maximum 60 kg. Bycatch in artisanal and commercial fishes of gillnets, set bag nets, trawl nets and long lines. Inhabits open ocean along the continental shelf, ocean mountains and canyons. Young often close inshore and in shallow areas. Feeds on schooling fishes (including mackerels, bluefishes, clupeids, needlefishes, lancetfishes and lanternfishes), squid, pelagic crustaceans, and rarely seabirds. Use long caudal fin into bunch up and stun prey. Females give birth to 2-6 free-swimming young.
