Investigation and Disease Prevention of SVCV Mortality Graph

Investigation and Disease Prevention of SVCV Mortality Graph

Detailed Description

Mean cumulative percent mortality of salmonids (rainbow trout, sockeye salmon, and Chinook salmon and koi exposed to SVCV or mock treatments. Mortalities in mock control groups were all less than or equal to 5% (symbols for mock treatments not shown in graph legends. Asterisks delineate mortality levels of SVCV-exposed fish species that were significantly different (p ≤ 0.02) than the corresponding mock-treated species. Sockeye salmon (1.5 months old [m]), Chinook salmon (3.0 m), rainbow trout (2.5 m), and koi (5.0 m) each received intraperitoneal injections of 6.5 X 105 plaque forming units of virus. Sockeye salmon fry suffered high mortalities, similar to the levels that the natural host (koi) experienced.
