3. Nile tilapia
Nile tilapia Fry is exactly economically important. It is widely develop fish quality. In both farming and food system in order to increase productivity and cost reduction as well as adding nutrition fish meat. 3

4. Gracilaria sp.
Gracilaria is the seaweed that found near the coastal area in the Gulf of Thailand and Andaman Sea. Including there are high protein and fat. So that the effects Gracilaria solution on the growth of Nile Tilapia Fry and rearing Nile Tilapia Fry by commercial feed Mixed with Gracilaria solution were increased significantly, weight, ADG and FCR(Feed Conversion Ratio) of Nile Tilapia Fry, the length and survival rate of Nile Tilapia Fry reared with commercial feed mixed with Gracilaria solution 300 grams/liter were 100%. 4

5. The objectives of this study were:
1.The effects of Gracilaria solution on the growth of Nile Tilapia Fry.
2. Rearing Nile Tilapia Fry by commercial feed mixed with Gracilaria solution and recorded growth rate ,survival rate and conversion ratio during the experimentation.
3.This study would be beneficial for aquaculture farmers and be a new way to take advantage of fish growth. 5
