Abstract/ Executive Summary:

This study was conducted with aiming to know the present status of small indigenous fish species (SIS) in Oxbow Lakes/baors and rivers as well as the availability of SIS of fish and their potentiality in the study area. Regular data were collected from some important fish landing center cum markets, Oxbow Lakes and rivers of the study area. The availability of small indigenous species (SIS) of fish declined to a great extent over the years and many of them are rare or endangered due to death of rivers and baors were brought under aquaculture. Besides these, Many of SIS of fish were being increasingly used as trash fish for fish feed purpose. As an over populated country, demand of SIS of fish is increasing day by day. After 1990s almost all Oxbow Lakes have been gradually trying to bring under aquaculture through local community or Department of Fisheries. The most significant message of this study is that, some vulnerable and endangered SIS of fish are locally abundant both in fish landing center, baors and rivers. So they must be conserved for their bioavailability and nutrition throughout the country that would be most intelligent efforts in favor of global ichthyo-biodiversity conservation.

Keywords: Ichthyo-Biodiversity Oxbow Lakes Critically Endangered Fish Jessore- Jhenaidah

Location: There are many baors (Oxbow Lake) and fish landing center of each region in Jessore & Jhenaidah among which 2 fish landing centers, namely Borobazar and Chuadanga bus stand fish market in Jessore, Borobazar and Jhenaidah central fish market in case of Jhenaidah and five important natural water bodies (3 baors and 2 rivers) were selected for this study

Start Date: 00-04-2012

End Date: 00-02-2013

Program Area: Resource Development and Management

Non-commodity: Data collection and collation

Objectives:

to knowing the availability of SIS of fish and identifying the status of threatened SIS of fish in the study area.

Methodology:

Visits of two times in a week were made in each of the baors and fish landing center. As the supply of the fishes varied with seasons collection of data were made in different seasons i.e. throughout the year by repeated visits in baors and fish landing center cum markets. Data were collected from interviews and focus group discussions with fishermen, retailers and consumers of fish, secondary literature, semi structured and structured questionnaires was developed, pretested and adapted prior to the survey proper. Fish Traders (Retailers), Fish Traders (Wholesalers), Consumers, Species Identification was the Target Group of Survey.

Achievement/Findings:

Small indigenous species (SIS) are playing a vital role in securing food and nutritional demands of the people of Bangladesh. For improving diversity & abundance of SIS of fishes, several pragmatic steps such as establishment of sanctuary, introduction of SIS-carp composite culture and development of new breeding technology must be ensured and implemented.
