T
he present study deals with length-weight relationship of
Atropus atropos
for which no information is available on this aspect
from Mangalore coast. Therefore the present investigation was undertaken. Fish samples were collected from fish landing center
(Mangalore) and fish market. The regression coefficient of male was found to be lower than female. From this observation, it may
be opined that female gained more weight with increase in length compared to male. Data on seasonal variation in condition factor
(K
n
) showed that K
n
values were more or less similar in both the sexes, indicating almost identical metabolic activity. Gonadal
development and high feeding intensity are the factors which influenced the condition factor. The seasonal fluctuations in the relative
condition factor of both the sexes could be attributed to the sexual cycle, food intake and environmental factors. From the present
study, it can be inferred that the variation in the condition of
Atropus atropos
was due to feeding activity and gonadal maturity.
