Growth and survival of porkfish (Anisotremus virginicus) larvae: comparing rotifers and copepod nauplii during first feeding

Eggs of porkfish (Anisotremus virginicus) were obtained from natural spawning events occuring at Seaworld Orlando and transported to the Tropical Aquaculture Laboratory. Eggs were stocked into 12 L experimental rearing tanks at 30/L to determine growth and survival of larvae fed rotifers (Brachionus...

Summary:Eggs of porkfish (Anisotremus virginicus) were obtained from natural spawning events occuring at Seaworld Orlando and transported to the Tropical Aquaculture Laboratory. Eggs were stocked into 12 L experimental rearing tanks at 30/L to determine growth and survival of larvae fed rotifers (Brachionus plicatilis - Cayman strain) and copepod nauplii (Acartia tonsa) during first exogenous feeding through seven days post hatch (dph). Larvae fed rotifers during first feeding exhibited higher survival than those fed copepod nauplii (35.7 ± 4.0% and 23.8 ± 4.0% respectively). Conversely, larvae fed copepod nauplii exhibited greater body length and body depth than those fed rotifers. Results suggest that porkfish is an ideal candidate species for existing aquaculture technologies. This study highlights the Rising Tide Conservation Initiative, a collabortion of researchers and stakeholders invested in expanding marine ornamental aquaculture and research.
