was completely without merit. And since 'Hot Air' Hawley apparently doesn't do retractions, here's the skinny -- which Lynne (Eluned) was kind enought to post on KoiShack yesterday:

According to the US Fish and Wildlife Service:

Host Susceptibility
In Europe, epizootics of VHS occur primarily in rainbow trout, Oncorhynchus mykiss; brown trout, Salmo trutta; and to a lesser extent in northern pike, Esox lucius (Jorgensen 1980; Meier and Jorgensen 1980). Natural infections have also occurred in grayling, Thymallus thymallus, and whitefish Coregonus sp. (Wizigmann et al. 1980; Ahne and Thomsen 1985; Meier et al. 1986). Outbreaks of VHS have been suspected in pollan, Coregonus lavaretus, and lake trout, Salvelinus namaycush. In the United States, natural infections have been diagnosed in chinook salmon, O. tshawytscha; coho salmon, O. kisutch; and steelhead (searun rainbow trout).

Fish shown by experimental challenge to be susceptible to VHS virus infection are Atlantic salmon, Salmo salar; brook trout, Salvelinus fontinalis; golden trout, O. aguabonita; rainbow trout x coho salmon hybrids; giebel, Carassius auratus gibelio; sea bass, Dicentrarchus labrax; and turbot, Scophthalmus maximus (de Kinkelin and Castric 1982; Castric and de Kinkelin 1984; Wolf 1988). Fish shown by experimental challenges to be refractory to VHS virus infection are common carp, Cyprinus carpio; chub, Leuciscus cephalus; Eurasian perch, Perca fluviatilis; roach, L. rutilus; and tench, Tinca tinca.

I should really give the credit to Roddy, even though he initially misunderstood the term refractory to mean that carp were susceptible.
