Bangladesh is reverine country which plays nursery ground of small indigenous fishes. But the open water system is reclaimed by anthropogenic interference of human. The river received large amount of discharge materials from industries, households and pesticides and fertilizer from agricultural practices by the riverside areas altered the physiochemical properties of water. Due to the contamination of water of the river, a number of fishes are declining affects the livelihood of the rural people. Thus it is prime importance to construct fish diversity structure of water bodies. Keywords : Small indigenous species, diversity, river, ecology, anthropogenic activities. Introduction Small indigenous fishes were considered those whose attain a length of 25cm or 9 inches 8. But there are some deviations of Jhenidah is an important district of Bangladesh because of its small indigenous fishes and considered length over 25 cm wonderful geographical locations adjacent to Indian territory, treated as SIS fishes 9. Over 260 fresh water fishes were present cris crossed by many rivers, Nabaganga and kaliganga are of which 154 are considered as SIS species 10 . Fish is the main important rivers which are considered as the tributaries of the dietary sources of protein covers 38% of the total protein Ganga- Padma river system play significant role in business, intake.SIS fishes have contain certain vitamins, proteins and communications, livelihood of the rural people, In addition, it minerals 11-14 . The flesh of the SIS fishes is very soft, tasty and helps in agriculture and a good number of fish diversity which is easily digestible. It helps to eliminate malnutrition and night the main source of protein for the rural mass. blindness. Our aim was to assess the present status of SIF fishes which help as baseline information’s for the Concerned Nabaganga and Kaliganga are the two main rivers which authorities and researches because no previous work have been contribute the prime open water resources in south western part done on the diversity structure of these rivers. of Bangladesh. Most of the people of these areas are farmers and depends largely on the productivity of these water bodies Methodology for fish, livestock grazing, irrigation, washing, cooking, bathing and urban set up. With the high intensity of population and farm Study was carried out from September 2009 to August 2010.Six practices, the productivity of aquatic bodies are declining as a sites were selected for investigation of SIS fishes. result loss of biodiversity occurs. 1 Table-1 Fish is the renewable natural resources of the earth and most of List of sampling stations are shown the protein intake was coming from the fishery resources 2-5. Sampling sites locations Fisheries sector contributes not only in national GDP but also in 6 Mirzapur Kaliganga river,sailkupa earning foreign exchange . Water bodies are wonderful gifts of nature and it provides lot of benefits with smallest amount care Sseikhpara Kaliganga river,sailkupa and awareness and also provide habitat of different fauna and flora .4 Bangladesh has wonderful geographical situations with Harinarayanpur Kaliganga river,Kushtia numerous water bodies in the form of rivers, lakes, ponds, Jhenidah sadar Nabaganga river,jhenidah canals, haor, baor (oxbow lakes) and beels (depressions). The open water resources were estimated at 4395966 hactares of Mathurapur Nabaganga river,harinakundu 7 which rivers and canals were 479737 hectares . More than four Mohiskundi sasan Nabaganga river,jhenidah hundred rivers were present in the past of which 43 rivers are international 7.

The fishes were collected from the fishermen and local people Conclusion of different selected sites of the river by using traditional nets and gears. Local fish markets were also regularly visited at The production of small indigenous fishes was declining day by regular intervals Common fishes were easily identified on the day due to anthropogenic activities. The components of the river spot according to the taxonomic keys and released immediately ecosystem did not functioning properly so that fish and other to the water. That fish which were difficult to identify, aquatic biota felt environmental stress .Awareness should be preserved in 10% formalin and brought to the laboratory. create among people of all sectors to come forward and save Identification was done with the help of key 15 and several biodiversity for the future existence of human. books 16-18.
