The Vic Thomas Striped Bass Hatchery at Brookneal, Virginia Thomas L. Johnson Senior Fisheries Biologist FishPro Consulting Engineers & Scientists 5201 South Sixth Street Road Springfield, Illinois 62703, USA Phone Number: (217) 585-8333 Fax Number: (217) 585-1890 Email address:tjohnson@FishPro.com A modern, $2.1 million dollar, 6,900 square foot aquaculture facility operated by the Virginia Department of Game and Inland Fisheries for production of striped bass and hybrids will be reviewed and illustrated by a 35mm slide presentation. The hatchery water supply includes a 5,300 lpm Staunton River water pump station and screened river intake. The intake includes an debris air-burst and water jetting system for management of river bed alluvial material. The process water treatment system includes pressure media filters, high efficiency propane-fired boilers interfaced with two-stage heat exchangers, low-pressure ultraviolet disinfection units and liquid oxygen-based aeration/degassing components. Fish rearing units include circular fiberglass tanks for adult holding and spawning, McDonald jar egg incubation and rectangular fiberglass early rearing tanks with a combined indoor rearing unit volume of 45 cubic meters. In addition to direct flow through operation with heat recovery, the hatchery can operate in a semi-recirculation based mode with 2,000 lpm flow capacity that includes the use of a 40 micron drum microscreen, air-driven rotary biological contactor (RBC), variable speed water pumps and the previously described water heating and aeration components. Intensive Phase 2 striped bass production is provided by four outdoor 5.8-meter diameter stainless steel circular tanks with a total volume of 89 cubic meters. Also located adjacent to the aquaculture building are two multi-temperature linear concrete raceways (volume 20 cubic meters) used to hold of pond reared striped bass fingerlings prior to stocking. System design criteria and cost data for this facility are presented. A brief overview of the planning, design engineering, construction and operational phases of the project are also discussed. 1
Abstract Use of a Recirculating Aquaculture System to Hold Sacramento Splittail and Native Fish Species Louis A. Helfrich Department of Fisheries and Wildlife Sciences Virginia Polytechnic Institute and State University Blacksburg, Virginia 24061, USA Brent Bridges, Lloyd Hess, and Don Ferris U.S. Bureau of Reclamation Tracy Fish Collection Facility Tracy, California Diana L. Weigmann, and Charles Liston U.S. Bureau of Reclamation Denver Technical Services Center Denver, Colorado 80225, USA A recirculating aquaculture system was developed to hold native fishes for experimental pumping trails at the U.S. Bureau of Reclamation’s Tracy Fish Collection Facility (TFCF), Sacramento-San Joaquin Delta, California. The TFCF operates to prevent the entrainment of juvenile and adult fishes, including endangered species, into the Delta Mendota Canal. TFCF uses louvers to direct into the collection facility where they are held in tanks, identified, measured, and then transported and stocked at selected sites into Delta daily. A high diversity (52 species) and large numbers (2-23 million) fish are salvaged annually from over 2.5 billion cubic meters of water exported to the canal. From these wild fish, the Sacramento splittail (Pogonichthys macrolepidotus) a threatened species, was selected and held in the recirculation system for 6 months prior to pumping trials. The recirculation system consisted of two sets of six tanks (235 gal/tank) each set with a biofilter, swirl separator, ultraviolet filter, and oxygen injection. After six months, splittail were randomly assigned to control or treatment groups and used to examine the efficacy of an experimental fish-friendly. Fish in the control group were used to characterize overall effects of the recirculating aquaculture system. Wild splittail exhibited rapid acclimation to the system and artificial feed, fast growth, high survival (>95%), and good condition (minimal scale loss, abrasion, and abnormalities to skin, eyes, head, and fins). Experimental fish were used to examine the effect of a Hidrostal pump to move large volumes of water and a diversity of fish species and sizes. At optimum discharge and velocity, fish mortality, descaling, and injury rates were minimal after pump passage. 1
