Abstract

Length-weight relationship of Phalacronotus apogon, locally known as “Ikan Lajong”, a freshwater catfish from Batang Kerang, Balai Ringin was studied. The biometric measurement of this fish species was also have been documented. Fish samples were collected from 23rd to 24th March 2022 at four distinct stations. A total of 66 individuals of the fish samples were collected during the sampling period. The mean weight of P. apogon is 362.86 ± 293.20, while the mean of total length is 43.13 ± 8.80. The length weight relationship has been expressed in linear regression. The length-weigh relationship obtained is log W = 3.1894 log TL + 2.723, whereas, the coefficient of determination (R2 ) is 0.9772. The results obtained showed that the growth pattern of the fishes was positive allometric growth with b values obtained 3.1894 in aspect of total length. This study provided the first baseline data of length-weight relationship and its biometric measurement of P. apogon from Batang Kerang, Balai Ringin, Sarawak.
