Lateral line depigmentation (LLD) has been described using a variety of terms, including hole in the head disease and head and lateral line erosion, and has been documented in many species of marine fishes, particularly ornamental fish in captivity. Few instances of LLD have been reported in freshwater fishes, however in recent years LLD has been documented in trout, char, and salmon in North American hatcheries. The etiology of this syndrome remains a mystery in freshwater fishes. In this session we will explore this syndrome as it applies to salmonids in culture, including presentation, diagnostics, avenues of investigation, potential causes, and implications for fish health and fitness.
