STUDY OF PRESENT STATUS OF FISH FAUNA AND WATER LEVEL AT TUMARIA WETLAND FROM US NAGAR OF UTTARAKHAND

摘要: Present investigation was carried out during July, 2014 to June, 2015 to study the fish fauna from Tumaria reservoir (Wetland) near Corbett Tiger Reserve, Uttarakhand. An annual catch of 648.08 quintals (cumulative catch, Dec., 2014 to June-15) was obtained in the year 2014-15. The group wise catch was dominated by the group'Ka'(Carps, 57%) fishes especially Labeo spp., followed by Kha-1 (with 17%), Kha-1and Kha-3 each (9%) and Ga (8%) from this reservoir. In Tumaria reservoir species wise catch data has declined mainly due to dense Salvinia. The seasonal average of fish catch was low in winter than pre-monsoon seasons mainly because of water level fluctuation and high wind velocity. During sampling dates, total catch 25.51 Q recorded stood maximum catch during month of June-15 (13.51 Q) at low water level (DSL). It is concluded that average fish production only 40 kg/ha/year was mainly because of less water nutrients and Salvinia infestation. area. Water level from dam site on every sampling dates were also noted.
