The bullrout, also commonly called freshwater stonefish or kroki, is a pale yellowish to dark-brown coloured fish that lives in tidal estuaries and slow-flowing streams in eastern Australia, from Southern New South Wales to northern Queensland, Australia.

This could justify manufacture of an antivenene, whereas the experience reported in this series certainly would not.

Bullrout are responsible for most fish stings that occur in upper tidal reaches and freshwaters of New South Wales and Queensland. & Hammer, M.P. In Queensland, stingings from the bullrout have produced symptoms as severe as those caused by the stonefish of evil repute (J. Trinca, 1968, personal communication). Poss, S.G. 1999. poisoning: Bullrout are a fish that tends to live in rocky, weeded area of coastal streams and estuaries.

Bullrout envenomation is known to cause intense pain. People are most often stung when they accidentally step on the fish.

In the absence of bullrout venom cross-reactivity it is unlikely that stonefish antivenom has a practical application in the treatment of bullrout envenomation. The Bullrout may migrate downstream during heavy rain periods.De Vis, C.W. Its spines are venomous.

They are well camouflaged and sluggish, preferring to stand their ground and erect their spines when disturbed, rather than to retreat as most other fishes do. Crude bullrout venom and venom fractions were assessed for protease, hyaluronidase, phospholipase and hemolytic activities, reactivity with stonefish antivenom, lethality to brine shrimp and ability to elicit pain in human subjects.Compared with venom obtained from frozen specimens, live fish venom-milking techniques rendered greater venom potency and improved storage characteristics.

The first blog of the year will look at the very ugly and potentially deadly stonefish.

It is the only member of the genus Notesthes.
