Although ocellaris clownfish (Amphiprion ocellaris) are acknowledged as the first and most popular marine ornamental fish bred in captivity, aquaculture practices for this species remain affected by knowledge gaps and inconsistencies in basic culture parameters. Due to their popularity, ocellaris clownfish represent a significant profit source for marine ornamental aquaculture farms worldwide; therefore, there is a vested interest in improving culture practices to increase production efficiency and reduce losses. Green-water larviculture introduces microalgae to the rearing tank to darken the water, presumably increasing contrast and prey visualization, as well as providing continuous enrichment to live-feeds. Unfortunately, rearing live microalgae is labor-intensive, costly, and requires specialized equipment, thus many ornamental fish producers rely on commercially available algae concentrates. Additionally, larval nutrition can also be crucial to the success of marine fish rearing, as they are unable to synthesize certain nutrients, like highly unsaturated fatty acids (HUFAs) and need to ingest these through diet. It is well established that nutritional deficiencies contribute to deformity rate within several aquacultured species. This may also be the case in the ocellaris clownfish, as issues with undesirable deformities continue to impact commercial producers. In the first part of this study, A. ocellaris larvae were reared for ten days using three different algae concentrates containing Tisochrysis sp. (T1, RotiGreen® ISO 1800) or Nannochloropsis sp. (T2, RotiGreen® Nanno and T3, RotiGreen® Omega) to determine which protocol yielded the highest survival and best growth compared against a no-algae control. Of these, T3 produced significantly higher survival than other treatments, and thus was selected for a subsequent experiment to assess effects of different densities of algae concentrates (0.015 mL/L, 0.03 mL/L, and 0.06 mL/L) on larval survival and growth. There were no significant differences in any of the algal densities investigated. Survival was recorded at approximately 60% in all treatments. Moreover, another experiment will be conducted to evaluate the inclusion of copepods within the diet, to mimic natural forage. For this study, ocellaris clownfish larvae will be reared for ten days with a diet of Parvocalanus crassirostris, Oithona colcarva, or a 50/50 mixture of the two at a rate of 5 nauplii/mL twice daily. Based on these results, further studies will be conducted comparing copepod inclusion against a standard larval reference diet to assess survival, growth, and rate of deformity development in post-metamorphic juveniles. Together, results of these studies will help to create new larviculture parameters for these valuable fish to help ornamental producers thrive.
