G. L. Bullock J.J.A. McLaughlin R.D. MacFarlane 1986 <p><span>Exposure of young striped bass Morone saxatilis (weight, 8.5–34 g) to a mixture of arsenic, cadmium, copper, lead, and selenium at 4 and 10 times the average environmental concentrations of 1–3 μg/L protected the fish from experimental infection with Flexibacter columnaris, the causal organism of columnaris disease. In four trials, all striped bass died within 7 d after a 2‐min exposure to 5 × 10</span>⁶<span>&nbsp;F. columnaris cells in untreated water. In contrast, no fish died after a single dayˈs exposure to the metal mixture followed by infection with F. columnaris and a second exposure to the metals for seven more days. When striped bass were exposed 5 d to individual metals, copper protected against infection and cadmium offered marginal protection but was slightly toxic after 2 d exposure. Arsenic increased susceptibility to infection, and lead and selenium were without an apparent effect.</span></p> application/pdf 10.1577/1548-8659(1986)115<227:EOFMOS>2.0.CO;2 en American Fisheries Society Effects of five metals on susceptibility of striped bass to Flexibacter columnaris article
