To evaluate availability of food fishes for examining parasites in biological education, 303 fish belonging to 36 speciespurchased at fish markets in Hirosaki, northern Japan were examined for metazoan parasites. A total of 198 (65.8%) fishof 28 (77.8%) species harbored at least one parasite within seven taxonomic groups, Monogenea, Digenea, Cestoda,Nematoda, Acanthocephala, Hirudinea, and Crustacea. Concurrent infections of parasites of different groups werefound in 25 (69.4%) fish species. Cestodes were found in the widest variety of fish (20 or 55.6% of fish species), andnematodes were most frequently (30.4%) detected from the fish examined. Abundance of parasites differed among fishspecies and individuals, with the mean abundance of parasites ranging from 1 to 531 among fish species infected. Foodfishes may be useful as material for biological education to have students realize that the parasites are common andhighly diverse, because fishes are easily obtained at fish markets and examination for parasites can be done even duringcooking.
