Biologi Reproduksi Ikan Selincah (Belontia Hasselti Cuvier 1831) Di Rawa Banjiran Sungai Air Hitam Kecamatan Payung Sekaki Kota Pekanbaru Provinsi Riau
ABSTRACT
Belontia hasselti is commonly found in the Banjiran Swamp of the Air Hitam River.
A study aimed to understand the reproductive biology of B. hasselti has been
conducted from February to March 2018. Fish sampling was conducted once / 2
weeks. Parameters measured were sex ratio, gonad maturity level, gonad somatic
index (GSI), fecundity and egg diameter. Totally 100 fishes (46 males and 54
females) were captured, they were 70.8 – 130.05 mm TL and 7.44 – 41.59 gr BW.
Male has a slimmer body, darker body color than those of the female. Sex ratio of
males and females was 1:1. In each sampling time there were male fishes with 1st,2nd
and 3rd maturity levels , while the female fishes were in 1st ,2nd,3rd and 4th maturity
levels. The GSI of male ranged from 0.20 – 1.14%, while that of the female is 0.75 –
28.94%. The fecundity is around 4,191 – 4,350 eggs/fish, and egg diameter was 0.8-1
mm.
