Water Systems
Aquaculture systems: Flow-through Pretreatment Water Source Rearing Tank Effluent Photographs by HBOI
Flow-through aquaculture systems Advantages Lower cost Simplicity Provides ambient food Requires lower skill level
Aquaculture systems: Recirculating Pretreatment Rearing Tank Water Source Post treatment Effluent Water treatment Biofiltration Disinfection
Recirculating aquaculture systems Advantages Environmental control Free of outside contaminants Fewer regulatory constraints
Methods of Cultivation Extensive vs. Intensive Intensive = Maximize production Limited space High density Complete diet High water exchange
