Abstract:
Five live or inert food organisms (adult Artemia, Moina, Tubifex worms, clam
meat, poultry egg custard) were evaluated as feed for postlarvae of
Macrobrachium rosenbergii. The postlarvae (avg 5.2+/-0.22 mg, 7.2+/-0.38 mm)
were reared in plastic pools (0.9 m diameter x 0.6 m) containing 100 I fresh
water, stocked at one postlarva per liter for 30 days, with five replicates
of each treatment. There were significant differences (p<005) in final
weight gains of the postlarvae (62.94-88.86 mg), final length gains
(16.45-20.71 mm) and survival (69.67-92.33%). The live Moina were superior
to the other foods with a significantly higher weight gain
(1708.92+/-54.03%), length gain (287.70+/-4.76%) and specific growth rate
(9.45+/-0.1%/d). The higher protein (66.16%) and n-3 HUFA (10.20%) levels in
Moina may explain these results.
