A Dietary Microcapsule Based on Single Cell Protein (Spirulina Platensis) for Milk Fish, Chanos-chanos, Larvae

Abstract

The purpose of this study was to evaluate differences between spirulina-based microcapsules and commercial diets on absolute, daily and specific growth and survival rates of milkfish larvae. Spirulina platensis was as a core diet in microcapsules with different matrix (walls). The first capsule wall was gelatin and fish oil, while the second capsule wall was gelatin, fish oil and whole egg. The control group was commercial diet. A total of 1200 larvae were used in this experiments using recirculation systems. Larvae are fed three times a day and increased regularly when the size of the larvae increases. The results showed that the effect of both sprirulina-based microcapsule diets on the absolute growth rate (AG), specific growth rate (SGR) and average daily growth rate (ADGR) of Chanos-chanos larvae fed spirulina-based microcapsule same as them which to be fed using commercial diet. The survival rate was as 80.6±11,171%; 84.6±8.443%; 83.8±16.496%, respectively. This study showed that Spirulina-based microcapsules had the same effect as commercial feed on the growth of milkfish larvae which means that this diet could replace commercial diet
