Fish Protein Hydrolysate

Fish is one of the most important foods in the human diet because of its high nutritional quality. One of the potential local foodstuffs in Grobogan is Nile tilapia (Oreochromis niloticus). Nile tilapia has a high nutrient content, especially protein. To obtain better benefits from fish protein, it can be processed into fish protein hydrolysate (FPH) products. Fish protein hydrolysates (FPH) which contain a mixture of small protein or peptides and free amino acids are beneficial for children diet, in preventing and combating malnutrition problems through readily absorbed essential amino acids. This study aimed to analyze the amino acid profile of Nile tilapia and fish protein hydrolysate (FPH) from Nile tilapia. The treatments included processing Nile tilapia into hydrolysate and analyse amino acids of Nile tilapia before and after hydrolysate. The process of making FPH uses a local microbial protease enzyme from Bacillus licheniformis. Amino acids composition was analysed using an internal method developed by Saraswanti Indo Genetech laboratory (18- 5-17/MU/SMM-SIG, UPLC). Data were analysed using the paired t-test statistical test. The results showed there were significant differences in the rate of all amino acid profiles (p<0.05), except L-Aspartic Acid, L-Tyrosine and L-Histidine (p>0.05). From the research, it can be concluded hydrolysate processing has an effect on the increase of Lglutamic acid and L-lysine amino acid.

Feed Utilisation

In order to eliminate use of fishmeal in aquafeeds, we evaluated the effect of total replacement of fish meal by a mixture of earthworm (Eisenia foetida) and aquatic fern Azolla filiculoides in the diets of Nile tilapia Oreochromis niloticus (Linnaeus, 1758). The experiment was conducted in O. niloticus fingerlings (initial mean weight = 5.6±0.2 g) for a period of 60 days. Five experimental diets isoproteic (30.4±0.6% protein) comprising control diet A0 and four test diets (A1 to A4) without fish meal were formulated. To satisfy essential amino acids requirements in test diets, the ratios 2:1; 1:1; 1:2; 1:5 between A. filiculoides and earthworm meals were used respectively in total replacement of fish meal. The diets were tested in triplicate. On termination of the experiment, the final mean weights in the test diets (10.79 to 11.94 g) were lower than 14.9 g obtained in group fed control diet (p<0.05). The best growth performance and feed utilisation were obtained in fish fed test diets A1 and A4 (SGR = 1.25 and 1.26% day-1; FCR = 2.37 and 2.31 respectively). Excess of lysine in test diets was found to affect the feed utilisation.
