The present study was undertaken to collect baseline data on the ecological features and fish and fisheries in Baigul reservoir located in the Tarai region of Uttarakhand. The data on fish community, fecundity, physico-chemical parameters, phytoplankton etc. were recorded at fortnightly intervals in the lentic and lotic zones of the reservoir. The fish fauna was comprised of major carps, cat fishes, minor carps and large populations of trash fishes. A total of 36 species of fish belonging to 13 families were identified in the reservoir and it was quantified that the fishery of the reservoir, belonging to group B₂ and group B₃ was most dominant in all three years. During the study period total fish yield of Baigul reservoir was 1,86,314 kg in the year 2014-15(69.18 kg/ha/year) from its total water area of 2693 hectare. Fish catch trend for the previous three years indicated the annual production of 2,00883 kg, 1,58204 kg, 1,86314 kg respectively for the years of 2012-13, 2013-14, and 2014-15. The average fish production from the Baigul reservoir for the three years was found to be 1, 81800 kg. The investigation also revealed that the maximum gain in length and weight was found to occur during spring season and summer months between the months of March to June. The spawning was found to occur in the monsoon months from June to September with the peak time in the months of July and August having two peaks of maximum. In Baigul reservoir the employment of gill net was most common. The contractors employed mostly the traditional gears and crafts for fishing. The fishing was performed from gill net, triangular net, hook and line, cast net and dragnet
