Total of Seventy three economic importance fish were recorded from Teleosts represented by Thirty Seven families. Among the families, the most dominant family Carangidae recorded with eleven species and followed by second dominant family Leiognathidae recorded with eight species. According to the season wise species composition maximum record of 62 species during post monsoon followed by 41 species at premonsoon, 35 species at monsoon and minimum of 33 species during summer. Over all total species about 13 species of fishes are recorded among all the seasons. Total of twenty two ornamental fish were recorded from Teleosts represented by seventeen families in Kovalam landing centre. Among the thirty seven families of the economic importance fishes, an average of percentage composition of the most dominant one was Carangidae (19.36 %) followed by second and third dominant family Leiognathidae (12.98%) and Sciaenidae (8.62 %).Thirty seven families of the economic importance fishes, an overall density varied among seasons by dominant in no/individuals is as follows 502771 (postmonsoon), 232284 (summer), 123473 (monsoon) and 113497 (premonsoon).The diversity of Economic important fish population varied from minimum of 1.528 (summer)to maximum of 2.391 (postmonsoon). In general, the Kovalam fishery a fairly good fishery potential. During mosoon and postmonsoon (November – February), the biodiversity of fishesin this area indicated a healthy ecosystem.
