Abstract/ Executive Summary:

An investigation was carried out on the fish species availability in the fish landing centers of Patuakhali district from March, 2012 to December 2012. Almost all the major fish landing centers (seven) were surveyed using questionnaire. A total of 138 inland and marine water fish and crustacean species were observed. Out of 138, 126 species belongs to finfish and rest 12 species to crustacean. Amongst the fin fish species, 61 were freshwater, 10 exotic and 55 marine water species.

On the basis of abundance, carp species, Tenualosa ilisha, Lates calcarifer, Trichiurus haumela, Penaeus monodon and Scylla serrata were recorded most abundant.

Keywords: Fish species, Fish landing center, Inland and marine fish species, Crustacean species

Location: Patuakhali district

Start Date: 01-03-2012

End Date: 31-12-2012

Program Area: Animal Health and Management

Commodity: Marine fish

Objectives:

The survey was carried out to study the fish species availability in the fish landing centers of Patuakhali district.

Methodology:

The study was carried out in Patuakhali district of Bangladesh. All the major fish landing centers of this district were included in this study. The fish landing centers are located at Mohipur, Patuakhali sadar, Bauphol, Golachipa, Kuakata sutki polli, Kuakata bazar and Mirzagonj. In order to collect data on fish landing center, field visits were made in the major fish landing centers of Patuakhali from March to December, 2012. Every fish landing centers were visited at least three times to get the seasonal variation data of fish species. Large fish landing centers (Mohipur, Kuakata bazar, Kuakata sutki polli and Patuakhali sadar) were visited four times every two months interval. In addition relevant information was also collected from primary and secondary sources. The primary data were assembled through field survey at the upazilla level using a questionnaire. The questionnaire form was filled in by interviewing the organizers, aratdars (assembler) and fishermen directly from the field. All the collected data were analyzed and the species observed in the landing centers were grouped in different categories.
