STUDIES ON MATURATION ,SPAWINING ,FECUNDITY AND SEX RATIO IN BARBUS (PUNTIUS) SARANA (HAMILTON-BUCHANAN ) FROM LAKE KOLLERU , ANDRA PRADESH.

Abstract

Barbus sarana contains only one batch of mature ova in
the mature ovaries to be spawned in one spawning act. It
spawns during July-September. The fecundity ranges from
11,201 to 224,248 ova. There is a positive curvilinear correlation
between total length and fecundity, the latter increasing
with length at a rate of less than cube of length. The stock
of this species from lake KoUeru appears to be more fecund
than that inhabiting Loni reservoir. The sex ratio indicates
that females outnumber males in all months and in larger
length groups. Females appear to reach a larger length
than males.
