All about Fish Vetting – Dr Richmond Loh
Pictured below are a selection of publications written not by ‘fish doctors’, but by doctors of veterinary medicine (DVM, BVMS or BVSc). Additionally, most of these authors have postgraduate qualifications related to fish health and diseases.

Staff at Melbourne’s international mail centre received a surprise when they found live sea creatures in a package sent by express post from Thailand.
The high-risk package, which was inspected by biosecurity officers, contained two ornamental tiger shrimp (Caradina Cantonensis) in water as well as a culture intended to be food for the shrimp.
The shrimp were discovered during a routine X-ray of mail by an officer from the Australian Customs and Border Protection Service who notified Department of Agriculture officers.
No species of live shrimp or crustacean can be imported into Australia. Although the shrimp were not exotic (they do exist in the warmer climate of Northern Australia), there are risks that freshwater marine life can carry bacterial and fungal pests and pathogens.
The shrimp had to be humanely euthanased. The Department of Agriculture is investigating the importation.

Here’s a great 2 page fact sheet on how to look after freshwater turtles by a colleague of mine:

One point of disagreement is the water pH, based on case discussions with other turtle veterinarians (Drs Lisa Winters and Peter Ricci). The pH of the water should lie between 7-7.6.
I wonder if anyone got pranked today.
Q: what sort of behaviour does a fish show when he’s frivolous and disrespectful?
A: Flippant behaviour.
Journal of Fish Diseases Volume 37, Number 4 (April 2014) Construction of KHV-CJ ORF25 DNAvaccine and immune challenge test Authors: J-X Zhou, H Wang, X-W Li, X Zhu, W-L Lu, D-M Zhang Author Affiliations: no affiliations available Source: Journal of Fish Diseases, Volume 37, Number 4 (April 2014) Page Numbers: 319 – 325 Available Full Text: Full Text: Subscription Required to view full text Format: PDF Size: unknown Location: Publisher’s Site Authentication: EBSCOhost EJS Abstract: KHV ORF25 fragments were cloned from Koi Herpes Virus-CJ(KHV-CJ) strains isolated in our laboratory. The amplified products were inserted into the eukaryotic expression vector pIRES-neo, forming recombinant plasmid pIRES-ORF25. The recombinant plasmid pIRES-ORF25 at 1 µg per koi, 10 µg per koi and 50 µg per koi was intramuscularly injected into healthy kois, respectively. The results showed that the recombinant pIRES-ORF25 could induce the production of specific antibodies in koi determined by indirect ELISA. The differences of immune effect between three doses were not significant (P> 0.05), but all of them could induce the production of neutralizing antibodies. The immune challenge test showed that the mortality of koi injected with PBS, blank pIRES-neo vector and nothing was 90%, 92.5% and 85% at 25 days. While the mortalities of koi injected with eukaryotic expression plasmid pIRES-ORF25 were 20%, 17.5% and 12.5%. Differences in comparison with the control group were highly significant (P< 0.01). Histopathological staining revealed that the tissues of the immunized koi did not change apparently. In conclusion, the DNAvaccine pIRES-ORF25 construct could well protect koi against KHVand had the potential to be applied in practice. Citation: J-X Zhou, H Wang, X-W Li, X Zhu, W-L Lu, D-M Zhang .

If you work in a fish shop, you might get asked this question a lot. “What sorts of fish can I put in my pond?”, “What are cold water fish?” and “which fish do not require a heater?”
There are some native fish such as the Pygmy perch and tandanus catfish. There are imported ornamental fishes such as the various Danios (zebra, leopard and pearl) and White Cloud Mountain minnows. And what else?
I came across the Department of Fisheries’ website on locations of feral fishes (http://freshwater.fish.wa.gov.au/default.aspx?st3) in relation to Perth. From the links provided I was able to find that there is more than the goldfish and koi that you can actually stock in your outdoor pond. I was a little surprised to find that some of the ‘tropical’ fishes can survive our winters.
A list of the various species of feral fishes found in water bodies around Perth include:
Note that some of the species may be considered noxious and should not be kept, and should be reported. See the list here – http://www.fish.wa.gov.au/Sustainability-and-Environment/Aquatic-Biosecurity/Translocations-Moving-Live-Fish/Pages/Noxious-Banned-Fish.aspx
Tomorrow I’ll be making a presentation to the students during a lunch time seminar at Murdoch University.
Come and join us! See picture for details.
