SCALE STRUCTURE, AGE AND GROWTH IN THE FRESHWATER CARP, LABEO CALBASU (PISCES/CYPRINIDAE) FROM HARIKE WETLAND, INDIA
34 / 38
Abstract
Age structure and growth profile based on the scale studies of 468
specimens ranging from 17-62 em total length of Labeo calbasu (Hamilton)
from Harike wetland (30°13'N, 75° 12'E), Punjab, India have been described.
the present study showed better growth in terms of two important growth
parameters namely index of species average size and population weightgrowth
intensity. Two distinct phases in its life history have been described
that indicates the optimum exploitation of this species from this waterbody.
Harvestable size is found to be fish of 34 em total length. The detailed
structural elaboration of scale (normal, regenerated, lateral line) has also
been done using scanning electron microscopy (SEM).
