The susceptibility of blue catfish, (lctalurusfurcatus), and reciprocal channel (l. punctatus) x blue catfish hybrids to channel catfish virus (CCV) was determined through several methods of exposure. Mortalities of blue catfish, when injected intraperitoneally with CCV, were similar to what would be expected with channel catfish. Histopathology of CCV-injected blue catfish did not deviate from that of similarly infected channel catfish. Infection of blue catfish and the hybrids by swabbing the gills, dipping fish in a virus solution, or by cohabitation with CCV-diseased fish were...

Oxytetracycline, as a prophylaxis against secondary bacterial infections, was injected into 531 largemouth bass (Micropterus salmaides) which were caught during a fishing tournament on Lake Seminole, Georgia. The injected fish, along with 531 control bass, were held for observation in a 1-acre canal contiguous with the lake. After 19 days, 4.3% of the injected fish had died and 2.2% of the control fish had died. The oxytetracycline was not beneficial in reducing mortality in the released bass.
