So, you have been given a strange aquatic creature and you need to draw some blood. Where do you get it from?
Check out the blood collection sites from my FB album at this link.
Why do it?
You can study it on haematology, run a serum biochemistry panel or submit it for bacterial culture. These are fantastic, non-lethal ways of checking on the health of the animal.
"Manatees are dying so quickly that some still have food in their mouths, while the dolphins and pelicans appear to be starving to death."
"The deaths don’t follow an obvious pattern."
"Investigators don’t know if the die-offs are the work of the same killer, or if by some coincidence, nature has produced three unrelated carcass piles at once."

I hope to see you here.
This Fish Diseases Workshop will be held before the World Parasitology Conference in Perth at our Murdoch University veterinary school and will be presented by Drs Supranee Chinabut and Susan Gibson-Kueh. It will be a prequel or satellite workshop to an International Parasitology Workshop that follows right after.

| Abstract: | This study aimed at a simple, rapid, reliable, practical, and non-destructive sexing technique for mature zebrafish (0.61 ± 0.011 g each). In the first experiment, 36 fish of each sex were selected on the basis of the presence of a prominent genital papilla on mature females and bred randomly. All the couples laid fertilized eggs with a mean fecundity of 304 eggs per female, for a 100% sexing accuracy. In the second experiment, 140 mature zebrafish were randomly selected and individually sexed like in the first experiment. Each fish was then dissected in order to confirm the reliability of this sexing technique through the observation of either the ovaries or the testes. Upon dissection, an accuracy of 100% was recorded. This study demonstrates that sexing mature zebrafish only on the basis of the presence of a prominent genital papilla on the mature female is a reliable technique. | ||||||||||||||||

This is a simple and well-laid out experiment to produce the data needed by licensing authorities to test for the safety of using antibiotics in fish. Here they were able to establish a 500 degree day witholding period for florfenicol in rainbow trout.

| Abstract: | An increase in fish production has consequently brought an increase in infectious diseases in fish farms. The use of chemotherapic drugs is the most effective instrument against common bacterial agents. The number of registered drugs for use in aquaculture is limited and often veterinary practitioners resort to the off-label use of chemotherapic agents authorized for different food-producing animal species. Florfenicol is well known for its outstanding effect against various pathogenic bacteria affecting fish, and therefore, it may be a useful drug for off-label use in aquaculture. The aim of this study was to evaluate the depletion of florfenicol and its major metabolite, florfenicol amine, from the edible tissue of two fish species, rainbow trout and sea bream, following treatment with medicated feed at a dosage of 10 mg kg-1of bw day-1, for 10 consecutive days. At prefixed time points after the end of administration (0.25, 1, 2, 3, 4, 6, 7, 10, 14 and 21 days after treatment), edible tissues (muscle plus adherent skin) from 15 individuals in each group were collected and analysed by HPLC, to determine concentration of the drug in the tissue. On the basis of the obtained concentrations, withdrawal times of florfenicol in the two species were calculated. The results indicate that a drug withdrawal time of 500 °C-day, as established by Directive 2004/28/EC, for off-label drug use is more than satisfactory to guarantee the healthiness of fish products against the risk of drug residues. | ||||||||||||||||

AQUATIC ANIMAL HEALTH CHAPTER
The Chapter of Aquatic Animal Health is a very diverse interactive group of veterinarians as this Chapter covers all aquatic animals (apart from reptiles, amphibians, birds and mammals), with particular emphasis on those species which are kept for aquaculture or otherwise commercially exploited, including but not limited to teleost fish, bivalve molluscs, marine shrimps (prawns), freshwater crayfish and abalone. Disciplines include medicine and management, pathobiology and epidemiology of aquatic animal diseases. Members of this Chapter aim to exchange knowledge and promote excellence in the diagnosis, treatment and prevention of diseases of aquatic animals, to advance the science and art of veterinary science as it relates to aquatic animals, and to further the professional education and training of veterinarians with a special interest in aquatic animal health. The Chapter also aims to encourage research in aquatic animal health, and to encourage exchange of knowledge with and collaborative work with other scientists working in the field of aquatic animal health.
How do you become a Member of the ANZCVS?
The award of Membership of the College is conferred upon a veterinarian who is eligible to sit and successfully passes an examination in a given Membership subject.
Candidates for Membership of the College should be eligible for registration as a veterinarian in an Australian State or in New Zealand. Candidates must have spent at least four years in a full-time veterinary activity between graduation and taking the examination.
Applicants will be assessed on their knowledge and skills at the Membership examination. Performance in the Membership examination is assessed on the basis that the candidate shall achieve a pass mark of 70% or above.
“The candidate is expected to demonstrate a high level of interest and competence in a given area of veterinary activity. This is judged by that standard of knowledge and understanding, practical skills, attitude, methodology and communication which would make the person suitable to give professional advice to veterinary colleagues not similarly qualified on problems or procedures often encountered or used in general practice, in the relevant area of veterinary endeavour.”
