Pengaruh Penambahan Ascorbyl Phosphate Magnesium (Apm) Dalam Pakan Sebagai Sumber Vitamin C Terhadap Kematangan Gonad Ikan Selais (Ompok Rhadinurus)
The research was conducted from 1st October - 27th December at Fish
Hatchery and Breeding Laboratory, Fishery and Marine Science Faculty of Riau
University. The aim of this research was to evaluate the effect of adding Ascorbyl
Phosphate Magnesium (APM) on gonad maturation of Sheatfish (Ompok
rhadinurus). The broodstock were reared in 12 (70 x 70 x 100 cm3) cages (5
fishes/cage), placed in 20 m3 concrete tank. APM was added to the prepared diet
in different dosage: 0 mg/kg diet, 600 mg/kg diet, 1200 mg/kg diet and 1800 mg/kg diet.
The result showed diet contained 1200 mg/kg APM performed the fastest
gonad maturation (56 days), 6.3 % of gonad somatic index, 2.4 % of ovi somatic
index, 858 of number eggs ovulated, 0.8 of egg diameter. The temperature range
from 28 – 300 C, pH 6 – 7, dissolved oxygen 3.95 – 4 ppm, and ammoniac 0,001
– 0,002 mg/l.
