Abstract

Cyclopoid copepod has a potential as live feed that can provide ornamental fish larvae with energy and essential nutrients, and promote their growth and survival, as well as affect their colouration. However, the nutrition, growth and nutritional requirements of this species are poorly understood. This research focuses on comparing the efficacy of enrichment types on copepods towards the growth rate, survival rate and colouration of Pterophyllum scalare larvae. The enrichment of copepods consists of four enrichment procedures (rice bran, palm kernel cake (PKC),Chlorella and yeast). This study was carried out over 50 days and the growth rate, survival rate and colouration (growth rate, survival rate, SGR and colouration) were used to evaluate the responses of P. scalare larvae towards different enrichment methods. Specific growth rates (8.0161 ± 1.4928 %; P = 0.775) and survival rates (66.667 ± 5.337%; P = 0.815) of fish larvae were found to not be significantly different (P = 0.775, P = 0.815; P >0.05). However, the colouration of the fish larvae was affected by the types of enrichment used (P
