Ichthyofaunal diversity and status with reference to physicochemical characteristics in Sharavathi Estuary, Uttara Kannada District


Author(s): Sudeep S. Kairanna and Ganesh C. B

Abstract: Estuaries are an important component of the coastal ecosystem. The current study conducted at three stations of the Sharavathi estuary revealed the presence of total of 32 species belonging to nine orders and 25 families. The members of order Perciformes were dominant with 14 families, of which Carangidae and Gerridae consisted of three species each, whereas Lutjanidae and Stromateidae had two species each. Among non-perciform fish, Pleuronectiformes and Clupeiformes consisted of three species each, whereas other orders had one species each. The distribution of fish species was lower in station 3 compared to other sampling sites. Analysis of physicochemical characteristics indicated that the levels of calcium, nitrate, sulphate and magnesium were higher at station 3 compared to other two sampling stations. Taken together, these results suggest that the decline in fish population might be due to the unfavorable physicochemical characteristics in part of the Sharavathi estuary.
