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:

  1. Egg incubators
  2. Recirculating Rearing Pens
  3. Adult fish ponds
  4. Release or transportation for continued use
