    I and some other MASA members received this information notification from DAFF.

    "Notice to Industry – for mollusc species susceptible to Perkinsus olseni

    French Polynesia has recently notified the World Organization for Animal Health (OIE) of a reoccurrence of Perkinsus olseni infection in wild populations of molluscs. Perkinsus olseni is a reportable disease Internationally and is currently considered exotic to the South African natural waters and aquatic animal populations. To protect their the aquatic animal population, countries such as Canada had in May 2013 put in place recommendation for refusal of entry of species susceptible to Perkinsus olseni imported from French Polynesia for the end uses of: Aquarium commercial, Aquarium private, Outdoor holding unit commercial, Outdoor holding unit private, Display in Zoo or public aquarium and Culture, until further notice. "

    I have no idea how to identify this disease. Perhaps @lobsterlady might be able to throw some light on this disease. We need to be concerned as clams have been imported from Vietnam of late. If any marine biologist out their would care to explain for us, it would be appreciated.

    Are you sure Dallas? Looks like Tridacna are also Susceptible.


    2.1. Susceptible host species
    Perkinsus olseni has an extremely wide host range. Known hosts include the clams Anadara trapezia, Austrovenus stutchburyi, Ruditapes decussatus, R. philippinarum, Tridacna maxima, T.crocea, Protothaca jedoensis and Pitar rostrata (Goggin & Lester, 1995; Villalba et al., 2004; Cremonte et al., 2005; Park et al., 2006; Sheppard & Phillips, 2008); oysters Crassostrea gigas, C. ariakensis, and C. sikamea (Villalba et al., 2004); pearl oysters Pinctada margaritifera, P. martensii, and P. fucata (Goggin & Lester, 1995; Sanil et al., 2010); abalone Haliotis rubra, H. laevigata, H. scalaris, and H. cyclobates (Goggin & Lester, 1995). Other bivalve and gastropod species might be susceptible to this parasite, especially in the known geographical range. Members of the families Arcidae, Malleidae, Isognomonidae, Chamidae and Veneridae are particularly susceptible, and their selective sampling may reveal the presence of P. olseni when only light infections occur in other families in the same habitat.

    I will do a little more digging.
    But I think it is great that DAFF and starting to communicate to the stakeholders. At least we are now getting recognized.
