Aquaculture is the use of man made facilities as well as natural environments to raise fish, algae, prawns, and various other aquatic organic matter. There are numerous methods involved, but the method used at the Arcata Hatchery, located adjacent to the Arcata Marsh (Figure 1), is quite unique. Using both seawater and treated wastewater from the Arcata Wastewater Plant, fish recieve all the nutrients and habitat needed for healthy growth. The wastewater is used like a fertilizer to feed the phytoplankton which is then used to feed the fish. The trophic levels that the nutrients work through are quite amazing, and the process has proven to be a success. The aquaculture project benefits from many different levels of environmental engineering and allows for economic benefits, instead of dealing with the consequences of wastewater infiltration into other water sources.

Aquaculture
Aquaculture is the use of man made facilities as well as natural environments to raise fish, algae, prawns, and various other aquatic organic matter. There are numerous methods involved, but the method used at the Arcata Hatchery, located adjacent to the Arcata Marsh (Figure 1), is quite unique. Using both seawater and treated wastewater from the Arcata Wastewater Plant, fish recieve all the nutrients and habitat needed for healthy growth. The wastewater is used like a fertilizer to feed the phytoplankton which is then used to feed the fish. The trophic levels that the nutrients work through are quite amazing, and the process has proven to be a success. The aquaculture project benefits from many different levels of environmental engineering and allows for economic benefits, instead of dealing with the consequences of wastewater infiltration into other water sources. All work done in the hatcheries is under the control of HSU's Fisheries Department.
Aquaculture Information
Here is an overview of the topics of interest for this project.
History and Future of Aquaculture
Who used Aquaculture in the past and who stands to benefit from it's present use.
Systems in Use for Arcata Wastewater Treatment Plant
Covers the use of Aquaculture as it pertains to the Wastewater Treatment Plant in Arcata, California.
Fish and Water Statistics & External links
Outlines the fish raised in the hatchery and their final destination.
