Abstract

This study estimated the length at first maturity and sex ratio of four fishes belonging to the Family Trichiuridae namely, Ganges hairtail Trichiurus gangeticus, Gupta, 1966, Sparse-rayed frostfish, Benthodesmus oligoradiatus, Parin& Becker, 1970, Longtooth hairtail Eupleurogrammus glossodon, (Bleeker, 1860), Coromandel hairtail Lepturacanthus pantului, Gupta,1966, from Indian waters. Specimens were collected from August 2020 to September 2021. The length at first maturity, of males, ranged from 34.6 to 43.2cm and for females it was 36.4 to 41.4cm. The sex ratio ranged from 0.95-1.34 (M: F). The present study aimed to give an insight into the parameters such as L 50 and sex ratio of Trichiurus gangeticus and Benthodesmus oligoradiatus.
