Client: Alaska Department of Fish & Game, Sport Fish Division
Location: Anchorage, Alaska
Date Completed: 2011
Highlights: the largest enclosed sport fish hatchery in North America at 134,000 square feet


The William Jack Hernandez Sport Fish Hatchery was built to ensure the continued and increased production of sport fish for Alaska’s south-central region.

The hatchery uses state-of-the-art aquaculture technology to raise King and Silver Salmon, Rainbow Trout, Arctic Char, Lake Trout and Arctic Grayling. They raise more species of cold-water fish in recirculating aquaculture systems than any other sport fish production facility in the United States. With more than 100 tanks, the facility is able to produce more than 6 million fish annually for release into rivers and lakes. The Arctic Char and Rainbow Trout supply the Ruth Burnett Sport Fish Hatchery in Fairbanks.


This 134,000-square-foot facility is the largest enclosed sport fish hatchery in North America. Since its completion, the facility has received awards for environmental and engineering excellence, including the 2013 Envision Gold Award from the Institute for Sustainable Infrastructure.


PR Aqua incorporated advanced water recirculation and partial reuse technologies in the culture systems designs to achieve a balance between reduced water use, improved control over culture conditions, and optimized water quality. This provided reductions in the volume of freshwater required, the energy required to heat water to an optimum fish-rearing temperature, and the amount of effluent water discharge.

Services Provided

PR Aqua provided bio-programming, system planning and design, equipment selection, tender support, construction review, commissioning, and operational assistance.
