We used hydrogen peroxide to reproduce gill lesions typical of a broad assemblage of gill diseases encountered in aquaculture and examined the degree of growth rate depression that it caused. Additionally, we compared growth rates of gill‐damaged fish when they were either kept separate from or cohabited with healthy untreated fish. In contrast to expectations, treated fish reared separately from controls exhibited a much more dramatic decline in growth rate (30% less than controls) compared with those reared with controls (13% less than controls). Although the effect was transient and persisted for only 2 weeks, it suggests that when considering the bioenergetic costs of disease and when designing studies to quantify the costs, the interaction of diseased fish and healthy fish needs to be considered.
