Abstract

This research had been designed using fiber to test different pellet feed on giant Bullfrog, Rana catesbeiana. The investigation aimed to evaluate pellet feed formulated  with different fortifi• cation ofseaweed  on the growth and metamorphosis ofgiant bullfrog tadpole. The seaweed was then added in to formulated diet with different dosage of 0.0; 5.0; I 0.0; 15.0%  of the diet. The result pellet were given to tadpole as treatment with 3 replications  for each treatment. All tadpole received 7-10  %bw/day ofration given twice each day. Every week biomass of the tadpole in each fiber was measured  to estimate the growth and adjusting  new ration offeed. The same time metamorphosis level V.'aS monitored.  Water quality parameters measured were tem• perature, pH, dissolved  oxygen  (DO), and total NH4-N.  The experiment lasted for 4 weeks  (28 days). The result can be concluded  that pellet added with extracted seaweed would result higher metamorphosis level but not for growth rate.
