Abstract
Cornetfishes are reported in tropical and temperate near shore marine waters in the Atlantic, Pacific, and Indian oceans. The present study was performed on the Blue spotted Cornetfish, F. commersonii from Nagapattinam (Tamil Nadu, India) concerning morphometrics and meristic characters, length-weight relationship and food and feeding nature. The morphometrics and meristic characters of the cornetfish had been presented. The results revealed that regression plot of the data for LWR indicated a linear relationship among the two variables. The r value for the cornetfish, F. commersonii was 0.90. In the present study, various food items were identified as ‘fishes, crustaceans (shrimps, crabs etc.), molluscs (cephalopods, gastropods and so on) digested contents and others (unidentified)’ and they had been segregated for calculating percentage occurrence of each food items. It may be assumed that this species has been a success like others as a result of aggressive superiority and pre-adaptation as noticed in the present study.
