Fish Vetting Techniques and Practical Tips – instructional DVD: Fish Vetting Secrets revealed!

2014/01/21 at 08:30 | Posted in Veterinary Fish Medicine | 1 Comment

After attending a multitude of conferences and courses like Aquavet II and Seavet, reading up on the literature, and doing teaching at the university, it’s really hit home to me that: there is no better way to teach or learn, than to show, or be shown.

FISH VETTING TECHNIQUES & PRACTICAL TIPS takes a ‘how to’, hands-on approach to demonstrate veterinary skills employed in working as an aquatic veterinarian. The 105 minute DVD comprises veterinary procedures including taking skin mucus scrapes and gill biopsies, skin ulcer treatment, injecting fish, blood sampling, anaesthesia, surgery, necropsy, histology processing, videos of live microscopic fish pathogens and more… That’s right, I’m giving away all my secrets so that fish clients can have greater access to trained aquatic veterinarians no matter where they are in the world.

After watching this DVD, you can deal with fishes with confidence!

This DVD is ideal for fish veterinarians, aquarists, aquaculturalists, public aquaria, local fish shops and to have handy as a training resource in veterinary schools, laboratories, clinics and zoos. It is a comprehensive resource that incorporates aquatic medicine and pathology.

Fish Vetting Essentials.

2012/05/27 at 12:37 | Posted in Veterinary Fish Medicine | Leave a comment

The web can be a great resource but you may also find that it is full of contradictory information overload. Like you, I have found that reliable information on fish health, disease and medicine is difficult to come by and is at best, fragmented.

This is why I have published two essential books on aquatic veterinary medicine.

So if you’re serious about fish health, these are two indispensible texts on fish you must have at your fingertips!

Fish Health Professionals – Land the Catch of the Year!

Fish Vetting Essentials is a comprehensive resource that incorporates elements of fish keeping, clinical medicine and fish pathology in a readily digestible form.

Important information for diagnosticians in this book include:

  • how to interpret water quality
  • how to diagnose common fish diseases
  • how to medicate fish
  • how to treat fish diseases using drugs available in standard veterinary clinics.

Supporting more veterinarians in aquatic veterinary medicine. Means more fish doctors for you!

2014/10/21 at 07:55 | Posted in Veterinary Fish Medicine | Leave a comment

It’s a common problem that many fish keepers and farmers encounter when they run into disease issues with their fish. No fish doctors can be found in their locality. But more correctly, no aquatic veterinarians available.

This year, as I serve as the President of the World Aquatic Veterinary Medical Association (WAVMA.org), much of the emphasis of my work has been in recruiting more veterinarians to support fish keepers and fish farmers by providing more tools and knowledge.

I’ve been working with the WebCEPD Committee at the WAVMA to recruit speakers for webinars. Webinars are the perfect way to connect people through space and time, and to upskill our colleagues. We’ve had excellent speakers present on diseases of barramundi and dolphins, surgery on fish and more to come including seahorses, koi, ornamental fish, amphibians. In return, the speakers will gain massive exposure and receive global recognition for their works.

I’ve also contributed to a few articles to fish and pet magazines, but my emphasis this year is within the veterinary profession. I’ve published a series of articles with my colleagues in the Companion Animal Journal (pictured). I’ve also contributed a few unique cases to the second edition of Self-Assessment Color Review of Ornamental Fish.


I’ve been spreading the message personally too, presenting at several international conferences (Sydney Zebrafish Conference, Denver AVMA Convention and St Kitts Ross University guest lecturer). This years not out yet and I’ve a full week scheduled in Singapore, come Nov/Dec when I present at the FAVA-SVA Convention, to the NUS-SALAS group and a three-day ornamental fish biosecurity workshop to the AVA-FQIA.

I’ve also supported the formation of WAVMA Student Chapters at Murdoch University, Sydney University, and we have the University of Queensland following suit.

These are all tools to help recruit more veterinarians to assist with fish clients and, to know who and where to refer fish clients to.

Which biofilter media is better? K1 or chips? Part 1.

2014/10/17 at 08:00 | Posted in Veterinary Fish Medicine | 2 Comments

I’ve just been sent a sample of new fluidised bed filter media, called chips (pictured below, right). They are wafer-thin, lightweight, plastic discs, with minute pores and are slightly positively buoyant.

How does it compare with K1?
K1 is an established filter media that is shaped like cart wheels and are slightly positively buoyant (pictured below, left).

Well, I’ve setup a rough experiment comparing the two.

2L chips
2L K1
2x 20L buckets
2x 10L water
2x 400mg ammonium chloride
2x aeration
2x bucket lids

I set each bucket up with 10L of water, ammonium chloride, aeration and the biomedia.
I then periodically perform water quality analysis, measuring ammonia, nitrite, pH and temperature, logging these into a notepad.

See part 2 when it becomes available (approximately 4 weeks’ time).

Can you give me antibiotics to treat my sick fish?

2014/10/15 at 08:05 | Posted in Veterinary Fish Medicine | Leave a comment

I often receive requests to dispense medicines by potential clients who’ve searched the internet and consulted with Dr Google.

Consider this…
Would you ask a medical practitioner or the pharmacist to do the same?

The short answer to the question in the heading is, yes, as a registered veterinarian, I can prescribe and/or dispense drugs including antibiotics for your sick fish. The long answer is, it depends.

Firstly, many fish diseases are indistinguishable without running special tests. Water quality is a clear example of how you can’t tell what’s wrong without testing. Additionally, many of the parasitic diseases are impossible to diagnose without using a microscope. A Good diagnosis is what underpins success of therapy.

Secondly, it’s not uncommon for my clients to be faced with one or more diseases concurrently. It’s not until we test that we can tell.

Thirdly, many do not understand the gravity of unscrupulous use of antibiotics. Antibiotics resistance is a real issue. Dr Google would do well to alert would be users to this worrying fact. A search on the internet or on my blog will reveal the alarming facts.

So before you reach for the treatment for you sick fish, consider if you could do it better.

Fish Joke for Mondayitis: How do clams enjoy their festivities?

Carotene and keratin. A lesson in pronunciation and spelling.

2014/10/10 at 07:45 | Posted in Veterinary Fish Medicine | Leave a comment

I was taking to some clients about why it is that we can feel that male koi get rougher around their gill covers and along their bodies. I remarked that I studied sections under the microscope, comparing male to female koi.

Normally, fish have living epithelial cells right up to the surface; unlike us, who have skin cells that form keratinised dead cell layers. But in the male koi, they seem to produce bits on their skin surface that appear like keratin on histology sections. I concluded that this is the reason that males are rough.

One of them remarked, “But fish have carotene, it gives them their colour and that’s what we feed them.”

And so we began our lesson in spelling and pronunciation.

“Ke-ra-tin”, not “ka-ro-teeeeen”.
