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.
View sample pages here –  eFishVetEssentialswLinks.

Thank you to my colleagues at the World Aquatic Veterinary Medical Association.

Fish Joke for Monday-itis: lawyer

2014/12/21 at 22:55 | Posted in Veterinary Fish Medicine | 2 Comments

Q: Why is the lawyer watching the Discovery Channel?

A: Because he was told NOT to go on a fishing expedition.

This was created by my cousin JL who’s a new law graduate. I’ve to admit that this went over my head. So here’s her explanation:

discovery’ is a process whereby each party is supposed to disclose all related documents in a matter to each other.

however. it is not supposed to be a ‘fishing expedition’.

you can’t ask for everything under the sun hoping to get something that is related.

Yep, I still don’t get it. How about you?

Can parasites be present on healthy fish? The discussion will surprise you – simple steps for excellent fish biosecurity.

2014/12/19 at 08:00 | Posted in Veterinary Fish Medicine | Leave a comment

Some people come from a view point of keeping a balance in systems of pathogens, host and environment as occurs in nature. I do not disagree with that, however, we ARE keeping animals in less than natural environments. Additionally, from a medical stand-point, we would prefer to keep pathogens out.

Many of the parasites I deal with are obligate pathogens (e.g. skin flukes [Gyrodactylus], gill flukes [Dactylogyrus], white spot disease [Ichthyophthirius multifilis], etc.) and do not exist as commensals, nor are they found free-living in the environment (although they may be temporarily recovered from the water, environment and objects, associated with infected fish).

Some apparently healthy looking fish can be carrying pathogens, however, you cannot see evidence of the parasites (they are microscopic) or they may not be showing signs of disease… yet. Over time, the pathogens may cause stress (even in low numbers), picking off the most susceptible fishes first, as they slowly build in numbers. Then suddenly, their population explodes and you have to deal with whole tanks of sick fish.

How do we prevent this?
Well, you’d have to practice good biosecurity and you’ll have no issues. I’ve attached a section from my book on what sorts of treatments you’d need to apply to new fish before introducing them to your tank/pond. This is ideal for high through-put systems such as ornamental fish retailers/wholesalers and re-sellers. This should remove the bulk of pathogens. For those who have time on their side (e.g. home pond owners), or those dealing with highly valuable fish (e.g. koi and discus), there is an additional step.

What’s this additional step?
Sentinels! After following the prophylactic dips, the new fish are held in quarantine in a separate pond/tank for 4-6 weeks. At this time, 2-3 of your resident fish are placed in the pond/tank to cohabit with the new fish. The reason for doing this is because the different populations of fish have not been exposed to each other’s mix of microflora (and possibly viruses). This will give you time to react in a closely monitored system, without exposing your beloved collection to disease.

And to make it even more fool-proof, there is an additional “pre-step”!
A pre-purchase exam. Just as they do for farm and domestic pets, we can also apply this to fish. The new fish can be examined for health by microscopic exam, blood tests and their environment checked. Preventive medicines can be given and advise of low stress methods in transporting fish can be given. So, before you make that next big purchase, make sure you book TheFishVet to check everything out.

Treating skin ulcers in fish (how to). – YouTube

2014/12/16 at 09:14 | Posted in Veterinary Fish Medicine | Leave a comment

Skin ulcers in fish can be due to a large variety of causes including water quality, immunosuppression, stress, bacterial infection and a host of parasitic diseases.

Just this week I’ve attended several cases of skin ulcers in fish that were caused by multiple factors.

  • Case 1: Koi with skin flukes as primary cause.
  • Case 2: Ammonia (and later, nitrite) issues due to ineffective biofilter.
  • Case 3: Low pH and copper toxicosis due to lack of buffers and use of hot water from the tap.
  • Case 4: Straight bacterial infection.

The key to a cure is to first, get the right diagnosis prior to treating.


Thus, to treat merely with antiseptics (e.g. Potassium permanganate) or antibiotics may not achieve a cure. You’d end up frustrated, and prolong the inevitable; fish will continue to suffer and die.

In this case we were able to diagnose skin flukes (on microscopic exam) as the primary cause of skin ulcers in the pond of koi fish. So, in addition to antibiotics and supportive therapy, the fish were also treated for flukes.

See how I treated this individual <>

The Powder Gel I used is available from <http://thefishvet.com.au/shop/shopping.html>. I’ve used it on many species including freshwater and marine turtles, seahorses, koi, goldfish, marine sharks and more. The only species it hasn’t worked in was the wobbegong shark. A must-have for every fish ulcer treatment.

I’d like to thank my client for allowing me to share this case with you.

Yours sincerely,

2014/12/11 at 07:20 | Posted in Veterinary Fish Medicine | 2 Comments

WAVMA WebCEPD B-1007 – Tropical Fish Tranquilization, Anesthesia & Euthanasia

Join us for a free webinar on Saturday, December 21, 2014 at 1:00 AM Australian Western Standard Time (Perth/Singapore/Hong Kong).
Click http://tinyurl.com/mt9faw5 to check your local time

Register now!


This webinar will review veterinary procedures, drug dosages and routes of administration that can be used to sedate, anesthetize and euthanize tropical or pet fish. Sedating or tranquilizing fish prior to handling for physical examinations and diagnostic tests, or surgery makes the process easier. Anesthetizing the fish prior to surgical procedures is essential, and euthanasia with an overdose of anesthetic (oral, injected or in the water) is sometimes necessary and can be quick and painless. This webinar is suitable for veterinarians, vet techs/nurses, vet students, research scientists and aquarists/aquarium husbandry staff.

Dr Nick Saint-Erne DVM, CertAqV (Quality Assurance Veterinarian, PetSmart, Inc.)

Learning Objectives – participants will learn:
1. How to use available anesthetic drugs, anesthetic depth monitoring & post-anesthetic recovery
2. How to construct and use anesthetic equipment and surgical tables, suitable for tropical fish
3. How to euthanize tropical fish using available anesthetic agents, when necessary

NOTE: this webinar will be recorded. If you register for the live webinar and are unable to attend, you will be sent a link to view the webinar at a later time.

Want CEPD credit? (Registration is required)
Information on how to access the recorded webinar (at no cost), and a short knowledge & skills assessment (KSA or quiz) covering the webinar’s principle learning objectives, in order to earn 1.5 hours of veterinary Continuing Educational & Professional Development (CEPD) credit will be e-mailed to all registrants in 7-10 days after the webinar.

As CEPD credit can be used towards re-licensing or registration requirements to practice veterinary medicine, we provide WAVMA Members a discount off the US$25.00 fee for CEPD ($5 for student members, $15 for all others).
