Add salt to ponds to reduce chytridiomycosis Amphibian Conservation

A study in 2000–2001 of captive green and golden bell frogs Litoria aurea in Sydney, Australia (White 2006) found that following addition of salt to a constructed pond the population remained free of chytridiomycosis for at least six months. Thirty-three of 40 green and golden bell frog tadpoles released survived to juvenile frogs in the salted pond. However, growth appeared slower in salt water than fresh water (first metamorph: 49 vs 43 days; last metamorph: 123 vs 76–80 days). Following addition of salt, the two striped marsh frogs Limnodynastes peroni tested were negative for chytridiomycosis. Striped marsh frogs had introduced chytridiomycosis to the pond and it had killed all but one of the previous green and golden bell frog population.  Following the initial outbreak of chytridiomycosis, uniodized table salt was added to the pond to achieve 1 parts per trillion (ppt) sodium chloride (3% sea water) in December 2000. Forty tadpoles were then released into the pond and were monitored weekly.
