Abstract
Seaweed is known to have many benefits as a source of nutrients in foods
including in fish feed. Seaweed is known to influence the improvement of growth
performance, nutrient absorption, the chemical composition of the body, fat
metabolism and disease resistance. This study aimed to test several types of seaweed
fermentation of the green and brown strains of Kappaphycus alvarezii, Gracillaria gigas, and Sargasum sp. as carbohydrates and its role in the growth, survival, digestibility
of feed and chemical
composition of the body of the fish juvenile.
The results showed an increase in growth, survival, level of digestibility
and chemical composition of the body. The highest growth rates shown by seaweed Sargasum sp. amounting to 150.45
± 10.06 provisional highest survival rate seen in the use
of green strain K. alvarezii 66.67
± 6.67, the level of digestibility of carbohydrates in the
range of 50.22% - 57.19% and protein between 64.88%
- 66.65%. The highest increase in glycogen in the liver looks at
the use
of green strain as much as 6.29 ±
0.89, while the muscles seen in the G.
gigas group as much as
7.29 ± 2.05. These results indicate that the use of seaweed to the diet had a
positive influence on fish juvenile.
