The present study was conducted to explore the changes in mineralization and morphology in response to graded levels of nitrate and phosphorus in Indian major carp. Nutrient content was performed for the culture of Indian major carps; Labeo rohita (rohu), Catla catla (catla), and Cirrhinus mrigala (mrigal) in ten fishponds. Softness of water is one of the major limnological criteria for fish breeding and rearing. Present work focuses on the influence of Nitrate and phosphate among the other physicochemical parameters on the breeding potentiality of Indian Major Carp (IMC). The limnological results of the breeding pond of the area are as follows: pH ranges between 6.62 and 8.01, temperature 24 to 35ºC, conductivity 280 to 440 μS/cm at 25ºC. Nitrate-nitrogen is one of the most important indicators of pollution of water; its range 0.428 to 3.534 mg/L and ammonia-nitrogen range is 0.356 to 1.384 mg/L, Phosphate ranges between 0.006 to 0.583 mg/L. Here, some active and statistically significant environmental factors are also determined which are responsible nitrate and phosphate of water. Production of spawn increases in some of the farms due to influence of some of these factors.
