摘要：A total of 143 specimens of Cyprinus carpio communis were collected from Dal Lake, ranging in length from144mm to 414mm, and in weight from 40g to 4450g. The length-weight relationship of the two sexes exhibitedsignificant differences in growth co-efficient (b) and showed deviations from cube law (Male ‘n’ = 3.15 andFemale ‘n’ = 2.80). Gut contents of the fish revealed that on an average, decayed organic matter (detritus)formed 45% of total food, while the remaining food consisted of both plant and animal matter. Arthropodsand macrophytes formed the main or basic food, whereas, oligochaetes, protozoa, rotifers and algaeconstituted its secondary food. The molluscan and fish remains formed the incidental food. On the basis ofgut content analysis, the fish was designated as detri-omnivore. Gastrosomatic index (Ga.S.I.) recordedhighest value in July, while lower values were recorded in February. Condition factor (Kn) recorded highestvalue during March in both the sexes. Condition factor as well as gastrosomatic index exhibited a decreasingtrend from higher length groups to smaller ones. Absolute fecundity of the fish varied from 3173 to 629230and the relative fecundity fluctuated in the range of 21-230 with a mean value of 91.17. The largest lengthgroup exhibited higher fecundity than smaller ones, and its Go.S.I indicated the fish to be spring breeder.
