Systems invloved with Wastewater Treatment and Aquaculture of Arcata Marsh
- Treatment of incoming water from Wastewater Treatment Site
- Fish Egg Incubator
- Juvenile Fish Rearing Pens
- Fish Hatchery
Incoming Material (effluent) from Wastewater treatment plant
- The water that is treated at the plant is pumped and mixed with saltwater from the bay to produce a mixture that the fish can survive in.
- This is accomplished by a pump at the headgates that controls water salinity as well as a forced air pump that helps regulate dissolved oxygen and screens water for dangerous compounds.
- Prior to 1991 the systems were all closed, but with the addition of numerous pipes connecting the ponds, it is now a continuously flowing system
Fish Hatchery System
The cycle that fish in the system grow in is as follows:
- Egg incubators
- Recirculating Rearing Pens
- Adult fish ponds
- Release or transportation for continued use
