Limnological Parameters affecting the Survival & Growth of Fishes of Govt. Fish Seed Farm Maharajganj, Bhadohi

Government fish seed farm Vikrampur which is situated 1.5 Km, distant from Maharajganj, Aurai has been studied for hydro biological factors with special emphasis on survival and growth of fishes. To assess the impact of various toxicants present in the water of all the nine ponds of Government fish seed farm Vikarampur, breeding experiments were conducted in the fish farm during two consecutive years.

The result have shown cancel water contains high amount of pH, alkalinity, BOD, COD, TSS, TDS, chlorides nitrates, chromium and sulfer with the chronic problem of low dissoloved oxygen (DO) Level. From the experiment it is just clear that the farm receives polluted water causes reduction in fecundity of fishes.
