Abstract

Abstract: The majority of public aquaria have at least one very large tank (>370, 000 liters, 100, 000 gallons) as part of their collection. The large water volumes can make treatment difficult when pathogens escape quarantine or cross contamination occurs. The cost and methods of dispersion of chemotherapeutics to control infectious agents (bacterial, protozoal, or metazoan) can be prohibitive in large volumes. Currently there are few treatments for stenohaline monogeneans in large aquaria that are efficacious, safe, and affordable. This case demonstrates the safety and efficacy of a decade long use of prolonged hyposalinity that replaced the repeated use of copper and organophosphate treatments to control a Neobenedenia spp. monogenean infestation. The use of prolonged 20 ppt saline water is safe for a list of species traditionally listed as stenohaline which makes altering salinity a useful tool in treating parasites with restricted saline tolerances. Abstract : How low can you go? Prolonged Hyposalinity Treatment Neobenedenia in Large Aquaria Highlights: Hyposalinity (20 ppt) is a safe, affordable, and effective method of control for stenohaline monogeneans. A list of marine teleosts and elasmobranchs that tolerate prolonged hyposalinity as part of a monogenean control program is provided to guide management for zoos, aquariums, and aquaculture.
