Abstract: Population structure and
breeding pattern of a few species of catfish in wetlands from two
geographically contrasting regions of peninsular India were studied. Findings of the
study show that there is a marked difference in the structure of populations
and breeding pattern existed for some species in the two regions. The reason
attributes to different climatic factors found in these regions. Apart from
this, functional and structural modifications in the anatomy of fish species,
its physiological adaptation to the environment also contribute to these
Key words: Distribution,
Breeding, Seasonality, Rainfall, Recruitment.
