Hatchery & Live Feeds Production Systems
Microalgae Culture Lab
The microalgae culture lab is equipped with flask, bag, and cylinder cultures for production of Nannochloropsis, Isochrysis, and Tetraselmis. Microalgae is used to feed rotifer cultures and as background algae in "greenwater” cultures of larval fish.
Rotifer Culture Lab
Rotifers (Brachionus rotundiformis) are the first live prey organism fed to first-feeding stage marine finfish larvae. UNCW collaborated with Amy Riedel (Aquatic Ecosystems Inc.) to "Beta-Test" a prototype intensive continuous culture rotifer system, which maintains rotifer densities of 3,000-4,000 ind./ml. This 200-L unit produces an average of 175 million rotifers per day.
Larval Rearing Tanks
The hatchery consists of four 200-L incubators for hatching eggs, twelve 200-L larval rearing tanks for raising larvae to juvenile stages, and nine 200-L raceways for nursery culture of juveniles under controlled illumination and temperature. The hatchery facility is supplied with 1 micron-filtered, U.V.-sterilized seawater for maximum purity. Larval rearing and nursery tanks are supported by a recirculating system for optimum water quality and environmental control.
