WAVMA conference 3 at St. Kitts

The World Aquatic Veterinary Medical Association’s Conference, held at St Kitts, has just come to an end.

I learnt a whole heap of new things from collegues from around the globe. I will be sharing these with my team Australia-wide, to consider different and perhaps improved ways of doing things in the plight to advance aquatic veterinary care.

I got to witness the enthusiasm of the veterinary students on aquatic animal health, at the largest WAVMA Student Chapter (kick-started by Dr Jenice Bell, now having had a few other successors including the two Courtney’s). They have all the backing of excellent student-centred lecturers (Drs Mark Freeman, Don Bergfeld and Michelle Dennis) plus the benefit of great facilities and tropical island at Ross University. With a strong focus on aquatics, it is becoming the go-to university for veterinarians who are wanting to pursue a career in this field.

Is the use of tonic immobility in sharks sufficient for surgical procedures?

Tonic immobility produces different responses in different animals. For example, in some reptiles it produces hyperalgesia (i.e. more intense feeling of pain), but in some rodents, it does produce some analgesia.

It has not been documented to have analgesic effects in sharks, and in some instances have been linked to hyperaesthesia (i.e. increased ability to feel).Therefore, additional analgesia is recommended when performing painful or invasive procedures

Therefore, additional analgesia is recommended when performing painful or invasive procedures


Some scientists also believe that tonic immobility can be a stressful experience for sharks. By measuring blood chemistry samples when the shark is immobile, it has been suggested that tonic immobility can actually put stress on the shark, and reduce breathing efficiency. However, it has also been proposed that sharks have a series of compensatory mechanisms that work to increase respiration rates and lower stress <;

WAVMA Aquatic Medicine Wetlab Workshop – WSAVA 2018

WAVMA Wetlab at WSAVA was Wonderful

By Nick Saint-Erne

As part of the 43rd World Small Animal Veterinary Association Congress in Singapore, WAVMA sponsored an Aquatic Medicine Wetlab on Monday, September 24 prior to the start of the congress programs. Drs. Richmond Loh, Julius Tepper and Nick Saint-Erne presented the wetlab, held at the Temasek Polytechnic School, through the courtesy of Dr. Diana Chan, Head of the Centre for Aquaculture and Veterinary Science at the school.

The program started with check-in at 9:00 and lectures beginning at 10:00 and the lab continuing until 16:00. Over 20 veterinarians and students attended the wetlab. The wetlab provided lectures introducing each topic, then a demonstration of the technique, followed by participants doing the procedure themselves on koi fish from the centre’s Aquaculture facility.

The topics covered were:

Water Quality Testing – Nick Saint-Erne
Aquatic Systems and Filtration – Julius Tepper
Fish Anesthesia – Nick Saint-Erne
Fin, Gill and Skin Mucous Biopsies – Richmond Loh
Blood Sampling Techniques – Julius Tepper
Necropsy and Sample Collection – Richmond Loh

Following the wetlab, Dr. Chan provided us with a tour of the Aquaculture facility at the school, with its advanced holding tanks and filtration systems manufactured by Apollo Aquaculture Group, based in Singapore. The wetlab was very successful with lots of great interaction between the teachers and participants.

Fish Joke for Monday-itis: aquatic currencies

We’ve heard of world currencies and cryptocurrencies (bitcoin, ethereum, bitcash and more).

What currencies do fish use, to buy and sell?

Here are a few:

• ripple (cryptocurrency)

• silver dollar (USA)

• goldfish (China)

• kip (Laotian)

• gourami (Paraguayan)
