Abstract

In the present study, 49 Hybrid (C a t l a c a t l a ♂ x Labeo rohita ♀ ) of variable sizes ranging from 4.4 – 27.0 cm total length and 0.52 –258.35 gm body weight were sampled from Al- Raheem Fish Hatchery, Village Ali pure shamali, Jhang road 18 Km from Muzaffar Garh to investigate the parameters of weight-length and condition factor. Log transformed regressions were used to test the allometric growth. Each fish was measured and weighed. It was observed that growth in weight is almost proportional to the cube of its length. The value of the slope b = 3.17 which coincides with the slope of that of an ideal fish. Condition factor (K) has positive influence with increasing length or weight. Regression parameters were found to be highly significant.
