Abstract

The present review reveals that most of the extant work on the effect of aquatic
pollution on fish reproduction pertain to the changes in percentage gonadal weight
and structural changes in the reproductive system in majority of the fishes studied.
Effect on hormonal titres and synthesis has been worked out in only few species.
From these studies, it is apparent that aquatic pollution retards the reproductive
processes in both sexes by impairing the gonadal development, inhibiting the
maturation of spermatocytes and oocytes, delaying ovulation, breaking and
clumping of yolk material in oocytes and suppressing the synthesis of gonadal
steroids via hypothalamo-hypophysial-gonadal axis. Ultrastructural studies are
lacking. No fish group, other than teleosts, majority being freshwater, has been
attempted so far. Most of the extant work are confined to Channa (Ophiocephalus)
punctatus, Heteropneustes fossilis, (Saccobranchus), Sarotherodon (Tilapia)
mossambicus, Clarias batrachus and Colisa (Trichogaster) fasciatus.
