| description | The species of Barbonymus collingwoodii with local name of Kepek is riverine fish
that has a thin body shape elongated with the back elevated, small head, pointed snout, small
mouth located at the tip of the nose. The purpose of this research was to know reproductive
biology of �Kepek� fish namely sex ratio, gonads maturity level, gonad maturity index,
fecundity, relationship between total length with fecundity, egg diameter and size
distribution. Fish sampling was done be weekly for three months from February to April
2013 in Opak river of Bantul regency using electrofishing. All fish samples was collected
than transferred to the laboratory of Aquatic Resource Management for lengt hand weight
measurement, and gonad investigation. Sex ratio data were analyzed with the \"chi - square\"
test to know the population balance of male and female. The number of eggs fish calculated
based on gravimetric method. Eggs diameter were analyzed using the Battacharya method to
know population size and ripening of eggs that ready to spawn. The total fish was 209
individual. The results showed total length ranged from 4.1 to 17.6 cm and weigh from 0.73
to 40.24 grams. The sex ratio was1.4:1. Comparison percentage the gonade maturity level
(GML) of I, II , III , IV between male and female were : (40,2:39,1) |
