Abstract/ Executive Summary:

The study was conducted to create a checklist of available species of marine puffer fishes of Bangladesh. Cox’s Bazar was selected as the study area as common marine fish landing stations are situated there. The study was conducted for a period of one year form July 2011 to June 2012. Puffers were sampled form the fishing vessels on landing stations after return from the sea and also form the local fish markets in four seasons viz. winter, pre-monsoon, monsoon and post monsoon. Most of the fishes were much abundant in the winter season than that of other seasons. After the completion of the study, a total of nine marine puffer fish species were found as- Takifugu poecilonotus, Chelonodon laticeps, Takifugu oblongus, Arothron stellatus, Lagocephalus lunaris, Takifugu vermicularis, Arothron Leopardus, Lagocephalus sceleratus and Arothron immaculatus. The most abundant species was Takifugu vermicularis followed by Lagocephalus lunaris while the lowest abundance was observed for Takifugu poecilonotus.

Start Date: 00-07-2011

End Date: 00-06-2012

Program Area: Animal Health and Management

Commodity: Marine fish

Objectives:

To make a checklist of marine puffer fish available in the country which will be helpful in awareness making among the people regarding the puffer fish and their intoxication.

Methodology:

Study area and period of investigation: The field investigations were conducted for a period of one year from July 2011 to June 2012. Fish samples were collected from two stations of Cox's Bazar Sadar Upazila, Bangladesh in four different seasons. The fish collection stations were Fishery Ghat Bazar and Nazirar tek Artisanal Fish Landing Center (Figure 1). The seasons were- (1) the dry winter season, from December to February; (2) the transition period, from March to May (pre-monsoon); (3) the rainy season, from June to September (Monsoon); and (4) the second transition period, between October and November (post-monsoon). Collection of fish sample: Puffers were sorted from the catch were directly collected from the fish baskets when the fishing boats came to the landing center and immediately preserved with 10% formaldehyde solution in plastic jar and brought back to the laboratory of the Fisheries Faculty, Sylhet Agricultural University. Fish identification: Collected samples were washed gently with tap water and then the morphometric meristic characters were pointed out. Taxonomic studies were done on the basis of the physical features of the collected specimens. The fishes were identified. To establish the views concerning taxonomy of a species, several specimens of different sizes were examined. Attempts have been made to provide valid scientific name of all the genera and species and were listed in accordance with the rules and principles as set forth in the international code. Catch composition analysis: The weights of each group of species were taken and their percentages of composition were determined. The total numbers of fish in each taxon were also recorded.
