The need for nutritional sources safer than traditional animal products has renewed interest generally in plants and particularly in microalgae. However, the implication of enrichment culture and type of microalgae to main staple food Artemia for seahorses, under a small-scale laboratory set-up remain ambiguous hence, this study. Herewith, the growth and survival of yellow seahorse, Hippocampus kuda exposed into Artemia nauplii enriched with different green microalgae species, Chlorella sp. and Scenedesmus obliquus and unenriched Artemia nauplii as a live food control for about 4 weeks with the basic water quality parameters maintained in its optimum range; temperature (28°C), pH at 7.8, and salinity (33ppt) were investigated. Among the three (3) treatment of enrichment, the individuals showed maximum growth in terms of length and weight when fed with Artemia enriched with Chlorella. The result further shows that the male species of H. kuda exhibited a greater rate of growth in terms of weight and length compared to the female species as confirmed in the mean difference of 2.150cm and 1.561cm, respectively. Thus, the greater the average weight and length the better effect of microalgae-enriched Artemia. Individuals under the Chlorella-enriched treatment also showed a 100% survival rate compared to other set-ups. These findings revealed that Chlorella-enriched Artemia nauplii are suitable food and enhances survivorship and growth of H. kuda, thus potentially providing a great and effective way incorporating more cost effective and reliable microalgae enhanced live foods into seahorse culture.
