The stream Jaldhaka is an icy mass feed torrential transboundary waterway of India, Bhutan and Bangladesh originate from Bitang Lake in Sikkim. Fishes are significant biologically just as a modest wellspring of protein. Moderating protein insufficiency creating nations like India. This stream starts and incompletely courses through the eastern Himalaya biodiversity hotspot thus wealthy in ichthyodiversity. A significant piece of stream water is, for the most part, preoccupied with the water system reason in the side-lying agricultural fields up and down its length of the studied zone. An investigation was completed from October 2019 to November 2019 to manage documentation of a Barilius Species alongside Physico-chemical properties in the downstream of the stream coursing through the Coochbehar area of West Bengal, India. The fishery of the stream is of subsistence nature and is under the intense pressure of anthropogenic exercises. The Physico-chemical parameters recorded during the examination time frame in the timeperiod are water temperature (25.90C-28.70C), TDS (63mg/l-67 mg/l), pH (7.2-7.4), DO (7.2mg/l-7.5 mg/l), Total hardness (45 mg/l-67 mg/l) , turbidity (0.93-8.82 NTU), BOD(1.9mg/l-2.0mg/l), chloride (5.76mg/8.84 mg/l), total alkalinity(47mg/l-63mg/l) Conductivity( 84.52 us/cm-147.9 us/cm), Nitrate (0.38 mg/l-0.59mg/l), phosphate( 0.018mg/l-0.02mg/l). This investigation is useful for detailing new conservation protection and the board management policy.Genus Barilius, an interesting group of Cyprinid fish, is mostly a resident of the hill streams. The present work is an attempt to document a systematic account of morphomeristic character of a species namely Barilius bendelisis under the genus Baritius from the northern part of West Bengal under Indian region along with proper illustrations and to reevaluation the general taxonomy of the Indian bariliine cyprinids in the beam of accessible information. A complete study on the biochemical composition of usually consumed and obtainable Barilius species of Jaldhaka river was done to estimate their nutritive assessment. Most significant biochemical nutrient composition of Barilius bendelisis like protein, lipid, moisture, ash calculated by standard ‘AOAC’ procedures (AOAC, 2005).The crude protein content in the range of 17.6-14% , the lipid content varied from 7% to 5.4%.Moisture content showed from 70.39% to 75.2% the ash content changed from 2.6% to 3.8%. Present work clearly indicates that Barilius bendelisis is the economically rich source of quality protein which can offer nutritional security, source of revenue generation and can resolve the protein requirement of the locality. Improvement of the production by aquaculture and use of small fishes encouraged the locality for a better approach to meet up protein hunger of this area.
