Population studies of three species of ribbon fishes off the Bombay coast

Populations of three species of ribbonfishes (Trichiurus lepturus, Lepturacanthus savala, Euplerogrammus muticus) off the Bombay coast were studied for meristic and morphometric characters. All meristic characters except pectoral fin ray count, showed interspecific as well as intraspecific variations. Regression studies for various characters showed a linear relationship and high degree of correlation to the total and head lengths. Variations between the sexes were found insignificant. A comparison of the mean ratios of body parts of samples from Bombay and Mandapam showed significant variations for L. savala and E. muticus.
