Redclaw Hatchery We were the first in Australia to trial a crayfish egg incubator (since 2004) that was originally developed in Finland and in the local Finish dialect is called a “Hemputin”. The Hemputin allows us to incubate eggs independently of the mother resulting in increased survival. An added advantage of the Hemputin is the juveniles produced appear to be Specific Pathogen Free. This increases survival and growth once stocked into the earthen ponds as the little crays are not burdened with fighting disease that they normally would contract while with the mother (see article on the Hemputin in Austasia Aquaculture Vol 21 No-2 – June 07)
