APLIKASI PAKAN BUATAN DENGAN KANDUNGAN ASAM LEMAK HEWANI DAN NABATI YANG BERBEDA UNTUK MEMACU PEMATANGAN GONAD KEPITING BAKAU (Scylla serrata)
ABSTRACT: An experiment was
carried out to evaluate the effects of different ratios of animal and plant
fatty acid on the gonadal maturation and spawning of mangrove crab, Scylla
serrata. Five test diets containing different ratio of essential fatty acid
were examined. Diet A,B, C,D and E contained animal and plant oil at ratio of:
3.5:2.5%, 2.5:3.5% 4.5:1.5%, 6.0:0%, and 0:6.0%.The Mangrove crab with an
average weight of 315 g, carapace width of 12 cm, and carapace length of 8.5 cm
were used for experiment. The experiment was arranged in a block randomized
design, using three replicates for each treatment. The crab were fed 3% of
biomass, and the experiment was held for 4 weeks.The result of experiment
showed that there were significantly different (P<0.05) among diets tested
on number of spawned crab but not for gonadal maturation. Feed containing
animal and plant oil of 4.5:1.5 % showed faster spawning rate compared to the
other feeds, while crab fed with only animal or plant fatty acid at the ratio
showed the slowest spawning rate.
