    Abstract

    Chennai Fishing Harbour, Southeast coast of India. The trawl bycatch consists of 45,527 ichthyofauna individuals collected fortnightly during the period June 2018 to April 2019. The recorded ichthyofaunal diversity includes 156 species belonging to 2 classes, 14 orders, 66 families, and 119 genera. The order Perciformes dominantes with 74 species (47%) followed by Scorpaeniformes (12%; 19 species) and Tetraodontiformes (11%; 18 species). Temporal diversity analysis revealed that the maximum species diversity was observed during the North-east monsoon (123 species) while the minimum was observed during the post-monsoon (107 species) period.
