Research at the Manchester Research Station focuses on captive broodstock technology for depressed and endangered fish populations, and the culture, genetics, marking, and tagging technology of salmon and marine fish species. A world leader in state-of-the-art salmon culture technology, Manchester was the first research facility in the United States to grow salmon in a marine aquaculture setting. Today, it is one of only a few research facilities in the country where species such as lingcod, rockfish, sablefish, and Pacific halibut are successfully reared. Unique features of the Manchester facility include a large floating marine net-pen complex for understanding the environmental impacts of commercial rearing activities; unique semi-natural and other specialized rearing systems for salmon and marine fish studies; a state-approved salmon quarantine facility; and systems for research and testing of passive integrated transponder tagging technology.

Ahtna Environmental, Inc. (Ahtna) provided a conditions assessment, engineering studies and design, and environmental permitting to repair the existing seawater pump platform that provides seawater to various research facilities at the Manchester Research Station.  Ahtna teamed up with Mott MacDonald and Hart Crowser to complete the engineering, condition assessment, and environmental permitting tasks, and conducted in-water repair work in the fall of 2015.  The Phase II scope of work included engineering design and permitting to install four new steel pilings to provide additional stabilization of the pump platform and reduce its reliance on the adjacent fish pans for stabilization.
