Development of a non-lethal hydrogen peroxide treatment for surveillance of Gyrodactylus salaris on trout farms and its application to testing wild salmon populations.

ABSTRACT: This study documents the development of a non-lethal sampling method to recover gyrodactylid parasites from large numbers of fish that will underpin an improved surveillance strategy for Gyrodactylus salaris. A review of published literature identified over 80 compounds that have previously been tested against gyrodactylids or closely related parasite species. Five safe and relatively fast-acting compounds were selected for testing to determine their efficiency in removing gyrodactylids from host fish in small-scale aquaria trials using three-spined stickleback infected with Gyrodactylus gasterostei as a model host-parasite system. The most effective compound was hydrogen peroxide; short-duration exposure (3 min) achieved a parasite detection sensitivity of 80%-89%. The practicality of exp
