Determination of Proximate Composition and Fatty Acid Profiles of Commercial Fish Feeds

Abstract

The proximate composition and fatty acid profiles of the selected fish feeds (S, A, G3, and G6) prepared with different rations were investigated. The results showed that the crude protein, lipid, moisture, and ash level in feeds were in the range of 44.07% – 46.69%, 15.72% – 18.32%, 6.54% – 8.41% and 7.44% – 11.37%, respectively. The percentages of total saturated fatty acids (SFA) and total polyunsaturated fatty acids (PUFA) were higher in group A than in all other group, whereas the corresponding total monounsaturated fatty acids (MUFA) content was lower. All of the feeds had significant levels of polyunsaturated fatty acid (PUFA). The n6/n3 ratio of feeds was in the range of 1.15 - 1.98. The data obtained indicate that the % composition of n3 PUFAs was lower for G3 feed. These feeds were good sources of EPA (in the range of 3.13% - 4.57%) and DHA (in the range of 3.41% - 8.50%). Therefore, it was concluded that these fish feeds are suitable as a balanced food choice for aquaculture.
