Title Sexuality in Polydactylus indicus (Shaw)
 
Creator Kagwade, P V
 
Subject Threadfin Breams
 
Description Sexuality and the apparent segregation of sexes of Polydactylus indicus are
discussed. This species is a hermaphrodite throughout its life with gonochoristic
ovotestis. Visual differentiation of sexes could be misleading; only microsections
of gonads reveal the true identity of sexes. When the ovary is active, the testis
in the same individual lies dormant and rudimentary and vice versa, leading to
an erroneous identification of sexes. The spawning is inshore with one of the
sexes dominant and hence are the earlier reports of concentration of one sex
In the oxnmercial landings. Gametes retain potency long after exposure,
signifying the possibility of artificial fertilization.
