Closed water aquaculture systems are more technologically advanced than the open water pond, cage or raceway structures. Closed systems are essentially huge aquariums in which the water is filtered and re-circulated. Although they are very successful in terms of fish production, these systems require pumps, accessories and are expensive to maintain.
In order for Closed Water Aquaculture to be sustainable it must meet the following Criteria:
- Can not damage the surrounding habitat.
- Water, Energy, and Feed management must be in place.
- Minimal to no escapes can occur.
- Must be consistently monitored for disease.
