| Summary: | The rising cost of imported fish feed ingredients have called for an intensive
research towards the production of high nutritional fish feed using cheap and
natural nutrient sources. In this study, seaweed and palm kernel cake were used
as alternative protein ingredients in fish feed and the enrichment of its
nutritional value was achieved by using solid state fermentation. Following the
fermentation process, the nutrient compositions of the three types of seaweeds:
Caulerpa lentillifera (Chlorophyta), Eucheuma cottonii (Rhodophyta) and
Sargassum fulvellum (Phaeophyta) were compared. Solid state fermentation
was conducted using fungus (Phanerochaete chrysosporium) and yeast
(Candida utilis) to improve the bioprotein production. The comparison between
the nutrient compositions before and after the fermentation showed that
fermentation process can increase the nutrient value of the bioprotein. Results
of the analysis showed that Sargassum fulvellumis the best type of seaweed
with the highest total protein, 52.28 mg/g, high percentage improvement of ash
after fermentation, 61.31% and contains high amount of carbohydrate, 445.89
mg/g which are very important in fish diet. Hence, Sargassum fulvellum can be
used as an alternative protein ingredient in the fish feed since it was rich in
nutritional compounds compared to the other types of seaweed tested. |
