Cleanseas Tuna

Project Summary

Project Title: Tuna Nursery Re-Design and Upgrade
Prime Contractor: Customer
Completion Date: 2015
Value:  $200,000 USD
Species:  Yellow Tail Kingfish

Project Scope 

Facilities at the Cleanseas Hatchery and Nursery site at Arno Bay Australia were designed to produce fingerling Tuna for on-growing in ocean-based cage production systems. In 2012 the farm was transitioning to the hatching and nursery culture of Yellow Tail Kingfish (YTK) fingerlings for open-ocean on-growing. Pentair Aquatic Eco-Systems, Inc. was employed to, together with the farm management and staff, redesign the Tuna Nursery system to produce large quantities of Yellow Tail Kingfish fingerlings. These nursery systems consisted of four 100 m3 culture tanks and associated recirculating aquaculture system (RAS) filtration components. The existing technology would support the addition of 65 kg of feed per day. The design feed rate for the new YTK nursery was 200 kg of feed daily while maintaining high water quality standards. The redesign included recommendations for a new drum screen filter sizing, new UV filtration, new biofilter configuration, new biofilter component hydraulic elevation layout, and new oxygenation system and components.

A four tank nursery system was reconfigured in 2014 and two 2-tank systems were completed in 2015.

Design feed rates in the four tank system were achieved in 2015.

Completion Date: 2013
Value:  $10,000,000 USD
Species:  Yellow Tail Kingfish

Project Scope

Kuterra Ltd. Partnership is a first nation’s owned and operated business funded by Tides Canada. Together with a group of nonprofit organizations they have built a sophisticated land based Atlantic salmon grow out facility close to Port MacNeill BC. The facility is capable of producing 390 tonnes per year of Atlantic salmon. This high profile recirculation facility was built in an effort to show the world that commercial scale grow out facilities for Atlantic salmon can operate on land, be sustainable, and operate profitably. The facility showcases state-of-the-art Recirculating Aquaculture Systems (RAS) and Partial Reuse design and equipment supplied by PR Aqua. Constructed by Derk Enterprises, the facility utilizes Fluidized Sand Biofilter technology, geothermal heating, and VSA produced oxygen. A state-of-the-art control MCAS system monitors system performance and data logs critical water quality parameters. Fish enter the farm into a bio-secure quarantine system which is comprised of a stand-alone RAS with a single large culture tank and water treatment system. Fish reside in this system for 6 months before they are transferred into the grow out RAS which is an independent system containing 5 large 48 foot diameter culture tanks. Fish stay in the grow out RAS for 18 months. The fish are transferred into the Partial Reuse purge system for 7 days before being harvested at a size of 4.5 kg.

Taste of BC Aquafarms

Project Summary

Prime Contractor: Customer
Completion Date: 2013
Value:  $600,000 USD
Species:  Steelhead Trout

Project Scope

The farm is designed to produce 100 tonnes annually of Steelhead Trout using recirculating aquaculture system (RAS) and circular culture tank technologies. The facility supports an economically viable business, provides training and research opportunities, and is a model for farm diversification and growth of freshwater aquaculture in Canada. Project proponents and contributors include Taste of BC Aquafarms (owner), PR Aqua Supplies Ltd. (now a division of Pentair Aquatic Eco-systems), Vancouver Island University, IPSFAD, Tides Canada, and many others. The treatment vessel for this farm is a significant innovative advance. Fluidized Sand Bioreactors (FSB) have been known as a superior mode of treatment in RAS facilities. However the design has historically required significant power consumption. To minimize costs, aeration has been limited. In this farm, the FSB has been submerged and is fed by gravity. This new design reduces pumping costs by at least 25% making it not only more efficient as a bioreactor but also providing more efficient double aeration. The treatment system is also combined into a large concrete vessel requiring minimal footprint and providing easier access. Pentair has provided the following services: bio-programming, system planning and engineering design, aquaculture equipment supply of both custom and standard products, construction review, commissioning, and operational assistance.

Completion Date: 2008
Project Value:  $300,000 USD
Species:  Chinook salmon

Project Scope 

The focus of the pilot program was the construction, operation, and evaluation of a Partial Reuse Aquaculture System (PRAS) incorporating circular culture tanks with dual drains. The pilot was evaluated relative to a flow-through raceway culture unit of equivalent volume and was based on a broad range of criteria including water quality, fish health and survival, and energy consumption. The results of the pilot program have been very positive, indicating that the PRAS delivered comparable fish growth, greater smolt survival, reduced precocity, and improved smolt-to-adult returns (SAR). As a result, PRAS technology is being considered for adoption in the continued efforts of the CPUD to expand and modernize their hatchery facilities. Further studies to evaluate other species, alternate fish rearing densities, and adult return data are ongoing today.

Special Conditions 

The larger Atlantic salmon, closest to their 18-month harvest timetable, are the most susceptible to plankton related mortalities. Air balancing throughout each site was required to give larger and more even upward water movement for each pen among all site pens. Changing air flow at one enclosure, should not affect air flow in the other site enclosures. Running diffuser air flow specifications needed to be maintained at all times. Quick airflow adjustments by on-site staff required to cater to different problem plankton species encountered during the plankton growing season.

1st Year Results 

With New PT4 Air Aeration Control System Installed:
• Major mortalities averted among all 7 sites for 2013 plankton growing season, even though 2013 plankton densities were recorded as twice those in 2012.
• Previous year’s large smolt mortality at one site, due to a specific jellyfish species invasion, was averted in 2013 by the same specific jellyfish invasion.
• An increase of 1.0 mg/L of dissolved oxygen added to the seawater for each site.
