Abstract
Fin clipping is unlikely to be a major health issue, but their effects on small fish under variable environmental conditions have not been fully tested. In this study, we explored how nitrate pollution and fin-clipping affect the natural ecto-symbiont community of three-spined sticklebacks Gasterosteus aculeatus. Our results showed that fin clipping has a neutral effect on the abundance of the ecto-commensal Trichodina spp. and the well-known pathogen Gyrodactylus gasterostei, and that such an effect is not influenced by a 4-week exposure to 50 mg NO3 - l-1. This nitrate level, however, markedly reduced the abundance of these two ecto-symbionts compared to controls at < 10 mg NO3 - l-1. In conclusion, this study suggests that fin-clipping is a valid non-destructive method for tissue sampling in fish, and that an ecologically relevant nitrate concentration can protect fish against some species of Trichodina and Gyrodactylus.
