Growth and Condition of Exotic Fish Grass Carp (Ctenopharyngodon idella, Steindachner 1866) Reared in Small Village Pond

The objective of the current paper was to assess the growth and condition of small village pond reared grass carp Ctenopharyngodon idella (Steindachner, 1866) on the basis of length weight relationship and condition factor.For current study length and weight of the selected species was measured in two phases during January to March 2021.The result depicted that length ranged from 19.1 to 63.1 cm (44.581±0.837cm) and weight ranged from 90 to 2902 g (1458.518±55.814g).The length frequency distribution showed that population was dominated by large fishes.The correlation coefficient (r 2 ) 0.811, 0.705 and 0.990 was noted during the phase I, phase II and pooled data showed the strong linear relationship between the length and weight variables.The growth constant or regression coefficient (b) of the studied fish for phase I, phase II and pooled population were noted as 2.336, 2.798, and 3.027, respectively.The value of growth constant (b) was <3.000 during the phase I and phase II showed the negative allometric growth while it was (b ≥ 3.000) for pooled population which resulted isometric to positive allometric growth of the fish.The mean value of "K" was more than 1.00 for the phase I, phase II and pooled population was depicted good condition of fish in small village pond.These findings clearly indicated that the growth of the fish was good in village pond which showed that aquatic environment of studied village was conducive for the fish.
