July 2010 - PR Aqua Project Receives Environmental Stewardship Award
The Alaska Department of Fish and Game has been awarded the Peg and Jules Tileston Award for Environmental Stewardship. Good stewardship is being demonstrated through a partnership between conservation and business interests working together on the William Jack Hernandez Sport Fish Hatchery in Anchorage Alaska.
PR Aqua worked with HDR on the design and engineering of the aquaculture systems and is currently supplying the aquaculture system to the Kiewit Building Group, the general contractor for the project. The Hernandez Hatchery is slated for completion in the spring of 2011.
The Hernandez Hatchery is located on the cooling water intake pond of a decommissioned military power plant. Site challenges included design of the hatchery effluent treatment and permitting for the 3,000 gallon-per-minute well field. Water and energy efficiency were important design considerations that, through implementation of reuse technology, were resolved in a way that will allow operators to recirculate up to 99% of process water in the primary fish culture systems. Water reuse has the added benefit of decreasing the amount of energy required for heating water as a means to accelerate fish development and growth. While significantly increasing production of fish, the new hatchery will discharge less effluent water than the existing hatcheries.
PR Aqua is proud to be playing a key role in this project during the equipment supply and start-up phases.
May 2010 - Ruth Burnett Sport Fish Hatchery Start-up About to Begin
After almost 7 years of planning, engineering, design and building the aquaculture system for the Alaska Department of Fish & Game we are very proud to announce that the Ruth Burnett Sport Fish Hatchery will be opening this summer. With a total construction value of over $30 million, this 50,600 sq/ft facility will raise 6 different species of salmonids for release into Alaska’s lakes and rivers to supplement natural populations for the sport fishing industry.
PR Aqua was responsible for the supply and design of the aquaculture system and worked closely with prime engineers CH2M Hill and general contractor Alaska Mechanical to deliver this project to the State on time and on budget.
The first fish are due to be placed in the systems in May and during this time commissioning staff from PR Aqua will be closely observing the start up of the systems and assisting the ADFG hatchery staff to ensure that all the equipment is operating as designed.

November 2009 - Worlds Longest Pescalator™ Installed in Washington State
PR Aqua has recently supplied the worlds longest Jumbo Pescalator™ at 36 feet to the Washington Department of Fish and Wildlife Lewis River Hatchery near Woodland Washington.
The Pescalator™ is part of a new fish sorting facility that was funded by PacifiCorp Energy, designed by R2 Resource Consultants and constructed by JH Kelly and includes new holding ponds, crowding systems, electro aesthetic baths and sorting tables. The Pescalator is being used to safely and gently lift adult returning salmon from the holding ponds up to the sorting area.
Pescalators have been in use for over 20 years in a variety of aquaculture applications and are a safe way to handle fish up to 50lbs where damage and trauma to the fish is prohibited.
PR Aqua is currently working with several other clients that are designing facilities with long Pescalators and we look forward to providing a safe and gentle means of handling fish at other hatcheries and fish passages.
June 2009 - Anchorage Hatchery Equipment Supply To Begin
The PR Aqua Team is just beginning production of the equipment for the Anchorage Sport Fish Hatchery which is the culmination of two years of engineering and design work in cooperation with HDR. PR Aqua will be working with Kiewit Building Group Inc. who are building the hatchery and installing the equipment with a projected completion date of June 2011. Stay tuned for future updates on this project.

May 2009 - Fairbanks Hatchery Equipment Supply Complete
PR Aqua has just completed the aquaculture equipment supply stage of the Ruth Burnett Sport Fish Hatchery in Fairbanks Alaska. Although there is still one year of construction and installation to take place by prime contractor Alaska Mechanical Inc., all of the members of the PR Aqua Team have gone the extra mile to ensure that the equipment was manufactured on time, on budget and to the highest standard. Congratulations Team on a job well done!

January 2009 - PRAS Pilot Successful at the Eastbank Fish Hatchery
The Eastbank Fish Hatchery located in Wenatchee, WA has just completed a year- long pilot Partial Reuse Aquaculture System (PRAS) for the rearing of Columbia River Chinook salmon from ponding to yearling size.
The Chelan County Public Utility District (P.U.D) was mandated to increase fish production at their facilities but faced limited water resources so PR Aqua was hired to design an alternative to their traditional method of using flow-through raceways to rear fish.
PR Aqua designed and supplied the equipment for a pilot size PRAS which consisted of a two 30 ft dual drain circular tank systems, a drum filter, a pump sump, three reuse pumps, an OxyTower™, two radial flow separators, and an oxygen monitoring system.
During the pilot’s operation, the State of Washington Department of Fish and Wildlife conducted a side-by-side comparison between the two technologies and it was noted that fish health and fitness were very good and mortalities were down in the pilot while overall water consumption was reduced by approximately 70%.
The pilot system has been deemed a success based on results from both the fish health and water quality monitoring programs and the Chelan County P.U.D. plans to extend the pilot for another year to explore the systems potential for further improvements in efficiency at increased fish loading.
