Picochlorum as an alternative to Nannochloropsis for grouper larval rearing

Green water produced with either Picochlorum S1b or N. oculata was shown to inhibit the blooming of vibrio, an opportunistic pathogen of fish. Grouper larvae reared in green water produced with Picochlorum S1b had the same survival rate but a higher growth rate than those reared in green water produced with N. oculata. These results demonstrate the potential benefits of replacing N. oculata with Picochlorum S1b for the rearing of grouper larvae.
