Abstract: Safe and effective live vaccines against enteric septicemia of catfish (ESC) were created through the induction of rifampicin resistance in native E. ictaluri isolates; these including rifampicin-resistant strain (RE-33) of Edwardsiella ictaluri originally isolated from the walking catfish Clarius batrachus from Thailand. Single immersion exposure of catfish fry stimulated strong acquired immunity against many isolates of E. ictaluri without the need for booster immunization.

Abstract: A universal mounting assembly for a light duty snow plow using a lower triangular frame, an upper triangular frame and a pair of spaced-apart rearwardly directed tubular members for attaching the lower triangular frame to a vehicle. The mounting assembly can be secured to a vehicle using a quick release mechanism regardless of the vehicles ground clearance. Additionally, the plow can be used in any one of a plurality of predetermined positions with the bottom edge of the snow plow blade remaining substantially flat against the surface to be plowed. An electric winch that is supplied power from the battery of the vehicle to which the snow plow is mounted, is used to raise and lower the snow plow.

Abstract: An improved method for diagnosing myofibrogranuloma (MFG) in walleye without harming the fish is described. Blood samples are drawn from walleye and creatinine and calcium levels are then determined along with the sex and length of the fish. These data are then analyzed and compared to data from healthy walleye using discriminant analysis. The process is effective for identifying approximately 88% of MFG-positive walleye.
