Abstract
The research was conducted from May to September 2012 in
experimental ponds Fishery and Marine Science Faculty of Riau University. The
aim of this research was to investigate suitable feed for the maturation of the
gonads of sepat siam (Trichogaster pectoralis) reared with different feeding
treatment such as Gonad Maturity Level (TKG), gonad maturation index (IKG),
fecundity, egg maturation and egg diameter. The research method used was
Completely Randomized Design (CDR) with three treatments and three
replications. The treatment in this study were P1 (Tubifex sp), P2 (Shrimp pellet),
P3 (Shrimp pellet + Vit E).
The result showed that good feed for the maturation of the gonads was
shrimp pellets + Vit E, reared for 42 days and the total fish reached TKG IV 75%,
index gonad somatic 11.7 %, fecundity of 15.105 eggs, egg diameter 0.82 mm.
The temperature range from 29 – 320 C, pH 6 – 8, dissolved oxygen 2.53 – 2.95
ppm, and turbidity of 15 – 22 cm.
