Abstract
Length-Weight relationship and condition and relative condition factor parameters for the five species (Lutjanus johnii, L. lutjanus, L.
malabaricus, L. russelii, and L. fulvus) of fishes belonging to the genus Lutjanus of family Lutjanidae were determined. The values
of the exponent (b) for males, females and combined sexes belonging to same species were found to be different. Results of lengthweight relationship studies showed the applicability of the cube law and a highly significant coefficient of correlation (r = 0.9) was
found to occur between length and weight for all five Lutjanus species, indicating the validity of regression plots. In present study,
Lutjanus species exhibited both positive and negative allometric pattern of growth. Condition factor (K) when analyzed against the
total length and weight of these fishes appeared to be vary with increase in the length and weight. The average value of the relative
condition factor (Kn) was found to be around 1 for all species except L.russellii, indicating that fishes were generally in good
conditions.
