A study was carried out to assess the effect of Stress Coat® on slime production in goldfish (Carassius auratus) and koi (Cyprinus carpio). The study also investigated histological changes that might be associated with slime producing cells, and wound healing in koi. Several formulations of Stress Coat® were investigated and the results showed that polyvinylpyrrolidone (PVP), also known as povidone, an ingredient of Stress Coat®, when used alone, showed significantly higher slime production in goldfish than salt and Stress Coat® without PVP after 25 h. The results also showed that koi treated with compounds containing PVP showed better wound healing than those not exposed to PVP. Histology results showed no difference between compounds tested with regards to density and number of slime producing cells.

The introduction and distribution of the carp, C. carpio, in Australia are examined. Historical reports, standard taxonomic techniques, and rote in electrophoresis indicate that at least three distinct populations of carp exist in Australia and that one population has hybridized with the goldfish Carassius auratus.
