Fish Joke for Monday-itis: tree talk

One coconut tree asks another as as they stood by the beach:

Will there be fish around here?

It’s a shore bet!

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)

Government has decided not to take a gamble on the ‘Carpageddon’ plan.

Together, scientists and veterinarians around the world have engaged with the NCCP about Australia’s plan to release the koi herpesvirus. So many questions were raised, such as:

● why were there higher rates of deaths in non-target species (e.g. rainbow trout, silver perch, Murray cod) than in carp during their transmission trials?

● what impact will poor water quality as a result of mass carp die-offs have on native aquatic, and peri-aquatic fauna?

● what consequences will bacterial (including botulism) and algal blooms (including toxic blue-green algae) have on water ways, and on watering stock and crops?

These are only some from a long list of questions of foreseeable challenges that would be almost inevitable, should the virus be let out.

Subsequently, the government has decided on a 12 month extension before making a decision. The extension will allow time for researchers to look into the current knowledge gaps and speak with more stakeholders.

“This is a comprehensive and coordinated assessment, and once completed, will play a critical role in the Government’s decision on whether or not to proceed with release of the virus.

“Whether to release the carp virus to control carp is a big decision and it is essential that we get this early work right. There will be extensive further public consultation before any final decisions are made.”

But it seems as though the NCCP are still fixated on using the virus against the carp.
