Abstract/ Executive Summary:

An investigation was carried out in fish landing centers and fish markets adjacent to Kaptai lake, Rangamati to identify the potentiality of fish landing centers, the diversity of available fish fauna and the marketing channel. The study was done by questionnaire interviews (QI) of fish traders, focus group discussions (FGD) and secondary data collection from April 2014 to March 2015 in 03 landing centers and 15 markets of Rangamati district. A total of 84 species of fishes, which consists of 75 finfish and 9 fish were identified during the study period. Among 75 finfish, 52 were indigenous freshwater fish species, 10 exotic species and 13 marine species. In fish group, 7 prawn and shrimp, 1 crab and 1 pond tortoise species were found. Different types of freshwater fish, marine fish, crustacean and dry fish were found in the investigated markets of Rangamati town. The most abundant freshwater fish species were Catla catla, Labeo rohita, Clarias batrachus, Cirrhinus cirrhosus, Channa punctatus. Few numbers of marine fishes including Latescal carifer, Euthynnus affinis and Mugil cephalus were also recorded. Macrobrachium rosenbergii and Penaeus monodon were found most abundantly during the study period. A total 20 species were threatened according to IUCN red list of Bangladesh including 7 vulnerable, 10 endangered and 3 critically endangered species out of 54 threatened fishes in fresh waters of Bangladesh. Among 7 vulnerable fishes 6 were available, 1 was rarely available. Among 10 endangered species 9 were available and 1 was rarely available. Among 3 critically endangered species 1 species was found available and 2 species were rarely available. Ten exotic fish species (Hypophthalmicthys molitrix, Ctenopharyngo donidella, Cyprinus carpio, Puntius gonionotus, Oreochromis niloticus, Oreochromis mossambicus, Pangasius hypopthalmus, Mylopharyngodon piceus, Aristichthys nobilis and Clarias gariepinus) were found in Kaptai lake during the study period. Fish biodiversity of Kaptailake is decreasing day by day due to habitat degradation and different manmade causes. Proper conservation measures should be taken to protect the threatened fish species from extinction.

Program Area: Conservation and Biodiversity

Commodity: Fish

Objectives:

The present study has been set up to assess the diversity of available fish fauna in this important lake of Bangladesh.

Methodology:

Fish market There are many markets in around Rangamati town. Among these 09 fish markets were selected for study. The study area includes- Bonorupa bazar, Rijab bazar, TNT bazar, Tobolchori bazar, Assambosti bazar, Ghagra, Vetvedhi, TNT bazaar and College ghat. Landing centers Three fish landing centers were surveyed during the study period. The landing centers are located in main town that includes BFDC fish landing center, Kaptai fish landing center and Mohalchori fish landing center in Rangamati. Selection of samples Total sample size of the study was 100 of which 70 were fish traders, 10 aratdar and 20 were fish retailer. Fish traders were categorized into three groups namely bepari, aratdar and retailer. Preparation of questionnaire Three different questionnaires were carefully prepared to interview the selected retailer, aratdar and bepari of this study. Period of data collection For the study the data were collected during the months of April 2014 to March 2015. Data collection Several visits were made in each of the landing centers and fish markets of Rangamati town. As the supply of the fishes varied with seasons, the data were collected in different seasons i.e. throughout the years by repeated visit in the landing centers and markets. Questionnaire interview and focus group discussion (FGD) For questionnaire interviews, simple random sampling method was followed for 3 bepari, 2 aratders and 3 retailers in each study sites per visit.

Achievement/Findings:

The study preliminary attempts to understand the status and current worries of fish diversity of Kaptai lake, Bangladesh. Loss of many commercially important fish species is the current alarming issue and its conservation is the only solution for this problem. Though this lake have been conserved by many rules and regulations but due to the lack of proper scientific data-base, it is becoming more difficult to select proper management and conservation strategy. However, present study has revealed some recommendations like ensuring water flow, developing fishermen’s awareness, preventing indiscriminate fishing of larvae and juveniles, effective implementation of existing fisheries laws and declaration of fish sanctuary to save diversity of Kaptai lake. Extensive research is required to prepare better data-base information on biodiversity and fisheries with abundance problems aiming to develop practical rule and regulations.
