Abstract

This objectives of this research are study on the growth of Nile tilapia fries. Rearing
red tilapia fry by commercial feed mixed with Gracilaria solution and recorded growth rate
(long weight and ADG) survival rate and conversion ratio during the experimentation.
Completely randomize design was used having fore treatments including commercial feed
(control ), the second third and forth formula mixed Gracilaria solution with 100, 200 and
300 grams/liter, respectively. Red tilapia fry have starting long and starting weight were 2.38
2.30 2.46 2.42 cm, and 0.30 0.26 0.30 0.30 g, respectively. Rearing in all treated were reared
in plastic tank (10 L) for 30 days. The result showed that commercial feeds mixed with
Gracilaria solution increased significantly, weight, ADG, and FCR of red tilapia fries. It was
found that the highest growth rate of red tilapia fries in commercial feed mixed with
Gracilaria solution 300 gram/liter. The increase in average of weight, ADG, and FCR, red
tilapia fries reared with commercial feed mixed with Gracilaria solution were 1.79 g 0.58
g/day and 1.75, respectively.The length and survival rate was not different significantly
among all formulas. The survival rate of red tilapia fries reared with commercial feed mixed
with Gracilaria solution 300 gram/liter were 100%.
