North Central Regional Aquaculture Center Projects Economics and Marketing Project: Economics and Marketing of food sized walleye, yellow perch, and hybrid striped bass in the North Central Region. Sept 1993-May 1997 Project Objective: Develop cost of production budgets and expected revenues for the raising of food-sized walleye, yellow perch, and hybrid striped bass on farms in the North Central Region (NCR). Principal Investigators: Susan Kohler, Southern Illinois University-Carbondale, Illinois, Marshall A. Martin, Purdue University, Indiana; Patrick D. O'Rourke, Illinois State Univeristy, Illinois; Jean R. Riepe, Purdue University, Indiana. Principal Accomplishments: HYBRID STRIPED BASS: Kohler compiled a mailing list of 56 producers of phase III hybrid striped bass (HSB) both within and outside the NCR. A mail survey was sent to these 56 producers to obtain data on production costs. The response rate was low due to a hesitation on the part of producers to reveal this information. Two large fish farms in Arkansas (Malone's and Keo) and one in Missouri (Osage Catfisheries) were visited to discuss HSB production and gather production information. In all three cases, other species in addition to HSB were produced, therefore, species-specific production figures were not available. Kohler compiled an annotated bibliography on HSB production and production costs. This bibliography is available from Kohler for anyone needing the information. Kohler also summarized HSB cost of production estimates from six published reports on HSB production. Those estimated costs were presented at the North Central Regional Aquaculture Center (NCRAC) Hybrid Striped Bass Workshop in November 1995. Hybrid Striped Bass Projects Project: Hybrid Striped Bass - Sept 1995 - Aug 2001 Project Objectives: Coordinate selection of various culture syustems and implemnt field testing; write an initial culture manual using information generated by all the hybrid striped bass research sponsored by the NCRAC; Provide associated fact sheets, bullentins, and videos for hybrid striped bass research in the NCR; conduct workshops presenting technologies developed through NCRAC - funded projects covering general methods of culturing this fish.

Project: Hybrid Striped Bass#7 - Sept 2001 - Aug 2004 Project Objectives: Investigate and document current and potential demand (prices and quantities) for hybrid striped bass (live and processed), clearly identifying consumer groups, processors, and distributors by location, seasonality of demand, size preferences, unique demand attributes, i.e., “healer fish” in Chinese culture, and impact of increased supplies on market prices of hybrid striped bass and competitive species; estimate the processing and distribution costs (supply chain costs and margins) to derive expected “farm gate live weight” prices as a function of producer and consumer locations; conduct limited taste testing on hybrid striped bass to determine the effect of different feed rations; develop a Web page that would be a component of the NCRAC Web site that would provide analysis results to clientele quickly and to allow easy updates; design and investigate willingness of hybrid striped bass producers to become a part of a current market information system; compare phase III production parameters and feed costs of hybrid striped bass/sunshine bass (female white bass H male striped bass) in ponds and recirculating aquaculture systems using commercially available diets (32, 36, and 40% protein) in a minimum of two locations (three feed treatments/location), with 100 g " 20 g phase III fish (minimum of three replications/treatment), in ponds at least 0.04 ha (0.1 acre), with a stocking density of 7,413 fish/ha (3,000 fish/acre), or in tanks at least 1.83 L/tank (500 gal/tank) with a 60 g/L (0.5 lb/gal) at harvest loading density. A need also exists to identifycost-effective, commercial available diets for phase III production.

The majority of this research is focused on the pathogenesis of the infection in commercially cultured fish, such as the hybrid striped bass, tilapia and angelfish. In addition, a rapid molecular polymerase chain reaction (PCR) laboratory procedure has been established for the detection and speciation of the major aquatic mycobacterial species. Various disinfectants are also being evaluated for their ability to eliminate mycobacterial organisms from the environment. Immunology Project Team: Stephen Smith The Commercial Fish and Shellfish Technologies Program.Virginia Tech The immune response of an animal is a major component that directly influences whether an animal survives in a particular environment. The ontogeny of the immune response and it's associated organ systems in hybrid striped bass, tilapia and sturgeon is being examined. Clinical medicine Project Team: Stephen Smith The Commercial Fish and Shellfish Technologies Program.Virginia Tech The laboratory has been involved with the standardization of blood collection techniques for fish and the establishment of normal hematological and blood chemistry values for various cultured fish species. Normal blood values for the various hybrids of the striped bass have been determined and recent studies completed on hybrid tilapia and summer flounder. Pharmacokenetics Project Team: Stephen Smith The Commercial Fish and Shellfish Technologies Program.Virginia Tech Chemotherapeutics are often used in fish to combat bacterial diseases. Unfortunately, only two drugs are legally approved for use in foodfish, and a number of common bacterial organisms of cultured fish have resistance to both drugs. Thus, another research focus of the laboratory is the acquisition of pharmacological data on various potential chemotherapeutants for fish.
