irradiated foods look like. After the lecture and video, the students were given the same attitudinal test (PostTest). Thirteen attitudinal questions were scored as Strongly Agree, Agree, Uncertain, Disagree, Strongly Disagree. One question on whether they would buy irradiated food products was scored as Yes or No. Analysis of mean variance were evaluated by SAS, 1987. RESULTS AND DISCUSSION Attitudinal questions follow with the pre and post test results. In all instances the mean attitudes about the benefit, safety, and wholesomeness of irradiated foods showed significant improvement (pcO.01). Students were less concerned about the potential of irradiated foods causing cancer (74% to 27 %); 84% said they would consider buying irradiated foods if available, up from 47% on pretest, and attitudes about the ability of irradiation to reduce the threat of foodborne illness were improved fi-om 3 1% to 75%. Evaluation of older consumers is currently under study to determine if consumer education, in general, will alter attitudes and affect buying behaviors.

BIGHEAD CARP: ASSESSMENT OF TWO POTENTIAL CANNED PRODUCTS Donald W. Freeman USDA, Agricultural Research Service Aquaculture Systems Research Unit University of Arkansas at Pine Bluff Pine Bluff, AR 71611 INTRODUCTION The catfish, bait minnow and Chinese carp industries in the U.S. were all born in Arkansas. Arkansas has over 65,000 acres of water devoted to aquaculture production (McNulty, 1996). Arkansas today trails only Mississippi in acreage and sales of catfish and leads the nation in bait minnow production and Chinese-carp-hatchery production (USDA, 1995). Commercial fish farming has a significant impact on the economy of the state and surrounding Delta region and has a potential for growth that far exceeds its present economic importance. Alternative fish products and alternative species would allow Delta fish farmers to diversify production in their ponds as a risk management strategy. However, little information is available on the marketing potential of alternative species such as bighead carp (Hvnonhthalmichthvs nobilis). Carp, as a group, make up the greatest production of fish by weight from worldwide aquaculture (Billard and Perchec, 1993) with bighead carp ranking third in total aquaculture output (Engle, 1992). Bighead carp have been raised in Arkansas since the 1970’s as a polyculture species in efforts to improve water quality in catfish ponds. Although other countries have established markets for this freshwater fish, bighead carp have not been marketed on a wide scale in the U.S. Arkansas fish farmers have sold bighead for resale in Asian ethnic markets as a live product. This market is easily saturated resulting in wide fluctuations in supply and price. Therefore, a higher-volume market outlet, such as a cannery, would provide stability and a constant market for bighead. Consumer acceptance of potential, catmed bighead carp product forms is relatively unknown. Regardless that the U.S. has not been a very sophisticated marketplace for canned fish products, with the exception of specific ethnic consumer demands, there may be room in the marketplace for new canned products made from non-traditional fish species (Regenstein and Regenstein, 199 1). Despite the emergence of frozen, convenience products and the more ready availability of fresh seafood, canned seafood is still consumed by more households than any other fish product form (Thomas and Engle, 1995). The most popular canned fish in the U.S. are salmon, ttma., and sardines in oil or water packs (Regenstein and Regenstein, 1991). In 1987, the U.S. imported 10.8 million cases of (105,000 tons) of canned tuna (Parks et al., 1990).
