Add to ORKGNot AvailableLength-weight relationship (LWR) and condition factor (K) of karut croaker Johnius carutta, Bloch, 1793 was studied using 3,406 specimens (1718 males and 1688 females) ranging in length from 11.00 to 24.50 cm collected from Visakhapatnam coast. Regression equation was calculated for males as: Log W=-1.4879 + 2.6801 Log L (R2 = 0.81), for females as Log W = -1.3327 + 2.5651 Log L (R2 = 0.78) and for pooled data as: Log W=-1.4378 + 2.6448 Log L (R2= 0.80) indicating negative allometric growth. The values of K were found to be above one in all the months in both sexes, and the value is influenced by gonadal maturity, spawning season and feeding rate of fish.Not Availabl
