GONADAL DEVELOPMENT CYCLE OF THE CRITICALLY THREATENED PUNTID FRESHWATER FISH PUNTIUS VITTATUS FROM THE RIVER TAMBRAPARANEI

J. Michael Antony Prabhu Arachi* and Krishnaraj

ABSTRACT

Maturation refers to cyclic morphological changes, which the male and female gonads undergo to attain full growth and ripeness. Gonads form the microenvironment enabling the germ cells to differentiate into ripe male and female gametes. The development of the piscine gonads has been described in terms of stages of maturity Puntius filamentosus (Victor et al (2004). The gonadosomatic index increases progressively with the development of the gonads in both sexes until the gonads are ripe, and the index then declines sharply in spawning and spent fish (Arachi, 2023).
