Journal Title: Indian Journal of Biology - Year 2017, Vol 11, Issue 1
Abstract
A survey was conducted on biodiversity of fish fauna and their conservation status around Kalna and its adjacent area. Burdwan district, West Bengal, India with an objective to prepare a register of fresh water fishes and assess their conservation status. Regular bi-monthly sampling was conducted from January, 2015 to December, 2016 by the help of fishermen using indigenous fishing methods and by using different types of nets. Fishes were also collected from local fish markets. We have collected 28 fish species belonging to 7 orders, 13 families and 24 genera. Order Cypriniformes was the dominant group with 11 species followed by Perciformes 7 species, Siluriformes with 5 species, Osteoglossiformes with 2 species and Clupeiformes, Beloniformes and Synbranchiformes each with 1 species. Out of 28 species, 20 species are least concern, 4 species are near threatened, 2 are vulnerable and 1 each are under not evaluated and data is deficient category as per IUCN (2013) Red List category. According to CAMP (1998) conservation status, 13 species are at lower risk near threatened, 5 species are under not evaluated, 4 species are vulnerable, 3 at lower risk least concern, 2 species are endangered and 1 species is under exotic category. The maximum species richness (26) was recorded at Dhatrigram and low species richness (22) was recorded at Kana. The highest Shannon value was recorded to be (3.107) at Samdruagarh. The low Shannon value was (2.831) at Kalna.
