The Effect of Feeding Frequency with Different Levels of Protein and Carbohydrates on Growth, Survival Rate and Albumin Content of Snakehead Fish (Channa striata)

Abstract

The purpose of this study were to evaluate the frequency of feeding with various protein (P) -carbohydrate (C) content in feed which produces the best growth, survival and albumin content of snakehead fish (Channa striata). A factorial patern with completely randomized basic design and two factors were used. The first was three different daily feeding frequencies, namely 2 times (F2), 4 times (F4) and 6 times (F6) while the second was the different protein-carbohydrate levels, namely P 35% - C 35% , P 40% - C 30%, and P 45% - C 25%. The obtained data was analyzed by analysis of variance. The results showed that the treatments produced the similar responses in survival rate of snakehead fish. The interaction between the differences in frequency of feeding and the different protein – carbohydrate levels had significant effect with p<0.05 on individual growth and albumin content of snakehead fish. Average individual growth in the treatments P 35% - C 35% - F4, P 35% - C 35% - F6, P 40% - C 30% - F4, P 40% - C 30% -F6, P 45% - C 25% - F4 and P 45% - C 25% - F6 was not significantly different but it was higher and significantly different from other treatments. The highest albumin content was observed in the P 45% - C 25% -F6 treatment, but it was not significantly different compared to the P 35% - C 35% -F6, P 40% - C 30% - F6, P45% - C 25% - F2 and P 45% - C 25% - F4. Based on the growth parameters, survival rate and albumin content, feed containing P 35% - C 35% with a feeding frequency of 4 times per day can be applied in rearing of snakehead.
