Semen has a unique composition containing spermatozoa and substances supporting the spermatozoa. The evaluation of seminal quality is essential in aquaculture for planning efficient artificial fertilization protocols in restoration programs involving supportive breeding together with other innovative conservation strategies as gamete cryopreservation. The evaluated semen quality parameters of Golden Mahseer, Tor putitora were: colour, volume, sperm density, spermatocrit value, sperm motility percentage and motility duration. Semen samples from ripe male brooders were collected during the period from April to July 2017 from the River Bhilangana and its impoundment (Tehri reservoir). The observations related to semen characteristics are based on 70 fish samples of T. putitora ranging from 220mm to 620mm in total fish length and weight ranging between 200grams to 900 grams. The colour of semen is milky white to creamy white. Semen volume varies from 0.4ml to 4.5ml in different individual brooders. The sperm density ranges from 1.28-2.23x109/ml per individual brooders. The sperm motility duration ranges from 38-59 seconds and the spermatocrit value range is 35.93% to 98.07%. The present study is aimed to evaluate the semen quality of Tor putitora for estimating the reproductive potential of male brooders and timing of optimal fertilization for seed production in the hatcheries.
