Abstract:

Present investigation deals with the fish faunal diversity in different habitat types in Hooghly district. Three types of floodplain water bodies were studied such as river, canal and ponds to determine the distribution of different fish species during different seasons. Results exhibit presence of 87 species in river Hooghly, 57 species in inland water and 47 species in different canals. Seven (7) diversity indices and One (1) similarity index were calculated i.e., Simpson dominance index, Simpson diversity index, Margalef’s richness index, Menhenick richness index, Shannon-Wiener diversity index, Maximum value of diversity index and Pielou’s evenness index to describe the relationship between species number and their seasonal abundance. Dominance was maximum (0.0885) in monsoon season and minimum (0.0354) in post monsoon in different canals. The Shannon-Wiener diversity value ranged between 2 -4 and it has a parallel relationship with different species richness index. Post monsoonal catch represents highest species richness and species diversity in all habitats. Evenness index exhibit its highest value in monsoon both in river and canal whereas it reached maximum in post monsoon in ponds. Maximum similarity was observed between river and canals (0.6418) and minimum similarity (0.5833) was observed between ponds and canals. River and ponds showed moderate similarity (0.6153).
