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.

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.

October 2008 - Dan Speas Fish Rearing Station Phase II Nearing Completion
The State of Wyoming is in the process of completing construction on the second large scale expansion of the Dan Speas Fish Rearing Station in Casper, WY.
Phase I construction was completed in August 2007. PR Aqua provided the aquaculture equipment including: large vacuum degassers, low head oxygenation (LHO) and multiple culture tanks.
Phase II includes more degassing units, several large flow LHO's and a rotary drum filter, all supplied by PR Aqua. This expansion, slated for completion in June 2009, will allow the State to increase production, as well as, improve the water quality of the facility. The original facility operated on thirty serial reuse longitudinal raceways and produced roughly 100,000 pounds annually. The new facility will retain twenty raceways for small projects. The new rearing units consist of twelve each of our 12', 16', and 20' dual drain circulars for a total of 36 new tanks with radial flow separators also provided by PR Aqua. These units are on first use water, then the reuse is treated by drum filters and LHOs before supplying four 36' x 10' concrete units with radial separators, then through an LHO battery before a final use through the last set of four 36' x 10' units. Base production is set between 270,000 to 300,000 pounds. Also incorporated with the new production units is an effluent treatment system to concentrate and remove TSS or process the waste to a locate irrigation district.

March 2008 - 12 OxyTowers for Mainstream Canada Hatchery
When Jack Edwards, Operations Manager of Mainstream Canada’s hatcheries was looking for more production at Boot Lagoon Hatchery he ordered 12 OxyTowers™ from PR Aqua.
Boot Lagoon Hatchery uses surface water from Great Central Lake, which carries an indigenous sockeye salmon stock; this requires the use of a very large UV system to disinfect all the process water for the flow-through hatchery. For cost and logistical reasons Jack made the decision to increase production without increasing the water supply.
By extending the rearing tank walls from 4 feet to 6 feet, each tank gained 30% additional volume. The installation of the complete OxyTower™ 500 reuse systems was engineered not only to handle the increased volume but also to increase tank exchanges from two hours to less than one. All in all Jack is very happy with the system and had this to say about them:
“The installation of the OxyTowers has resulted in a net gain of 30% in fish production in the extended reuse tanks while using 50% less O2. We no longer need to use oxygen diffusers in the tanks and we find that the reuse system allows for more efficient application of treatments such as the Supersmolt system. We are very happy to have achieved these results without impacting either the footprint or the water use of the facility”

January 2008 - New Heathro™ Pump for Powell River Hatchery
 The Powell River Salmon Enhancement Society has just taken delivery of a new gas powered Heathro™ Fish Pump to assist in the delivery of Chinook, coho and chum salmon fry. They produce close to 2,500,000 fry annually for release along British Columbia’s Sunshine Coast north of Vancouver.
The Heathro™ Pump will greatly improve the efficiency of their fish loading operations and will reduce the need for fry to be moved by net from the rearing tanks to the transport truck making life easier for the volunteers and the fish. In the past, fish were crowded and netted from the rearing tank, carried up to 60 feet to the transport truck and then up a ladder into the truck. Now two people will crowd the fish in the tank, and the fish will easily and safely be pumped up into the truck.
The Powell River Salmon Enhancement Society is a non-profit organization and works in partnership with the Pacific Salmon Foundation. They rely heavily on a dedicated team of volunteers and receive funding from the Department of Fisheries & Oceans, and through donations and fund raising.
November 2007– OxyTower Retrofit at Target Marine Hatchery
 Target Marine Hatcheries in Sechelt, British Columbia has two full recirculation hatchery cells of 550 m3 each, the Target Marine Hatchery staff is well acquainted with state of the art recirculation technology. This summer they made the decision to convert much of their old 30’ tank field from flow-through to partial reuse by purchasing and installing five OxyTower™ 500’s helping the hatchery move to a partial reuse system.
Due to the water shortages in the summer, Target has only been able to operate these tanks at full capacity for eight months of the year and been limited to the amount of fish they could produce but with the new OxyTowers™ they are able increase production while improving the quality and reducing the quantity of water required. Rob Haines, Hatchery Manager, said, “I am extremely pleased with the units’ performance and ease of install.”
Each of the PR Aqua OxyTower™ 500 gas balancing systems for Target included: gas balancing tower for flows of up to 500 USGpm, header tank and stand, pumping and oxygen distribution equipment which arrived on site ready to install at their culture tanks.
June 2007 - Proud Sponsor of Water Reuse Short Course
PR Aqua is proud to support the 2007 Reuse for Intensive Fish Culture Short Course organized by Freshwater Institute & Wyoming Game & Fish Department which provides a valuable opportunity for fish culturists to learn about emerging culture practices and technologies for aquaculture facilities.
March 2007 - Microscreen Drum Filter Internal Weir
 PR Aqua has an excellent, new option that enhances our long standing line of microscreen drum filters. We now offer our RFM drum filters with an internal weir for level control. What this means to our clients is that there is no need for our client to design level control for the drum filter in downstream plumbing, it is all taken care of within the unit. The weir maintains the water level within the drum filter housing which keeps the drum submerged to its design depth. This optimizes the performance of the filter and reduces the cost of installation as well as eases operation. The IW series of filters are quickly becoming our most popular unit.
November 2006 - PR Aqua and Aquafine Corporation Sign Distribution Agreement
