Atlantic salmon were exposed to hydrogen peroxide (1.37-2.58 g l(-1)) over a range of temperatures (10.4-16.0 degrees C) simulating treatment for sea lice. Gill tissues and behaviour were monitored. Exposure to 2.58 g l(-1) for 20 min caused total mortality (n = 18)while a shorter exposure, 10 min, at the same temperature caused only one mortality. Exposure to 1.37 g l(-1) for 20 min ar 10.4 degrees C caused no significant damage to gill tissues. There is a significant correlation (r = 0.895, F = 24.13, P <0.01) between the level of exposure and the degree of gill damage. (C) 1997 Elsevier Science B.V.
