Subject: AquaVetMed: Zebrafish Biomedical Research Workshop (King’s College, UK) – May 3-4, 2013

Zebrafish: an animal model in biomedical research – International Workshop (May 3-4, 2013)

Location: King’s College London (UK) harboring one of the largest European Zebra fish research facilities.

This workshop is the result of a collaboration between University College London, King’s College London, FGB, and COST action BM0804, the European Network on Fish Biomedical Models (EuFishBioMed).

Lectures will provide the latest information on the organisation of a modern Zebrafish (zebra danio) facility, animal husbandry and care, health monitoring, GMO technology, international legislation and guidelines and applied research technologies. Demonstrations of frequently used techniques are part of the programme.

With FishMap you can find out what fish occur at any location or depth in the waters of Australia’s continental shelf and slope. You can also create species lists for any region that include photographs and illustrations, distribution maps and current scientific and common names.

It has the known geographical and depth ranges of over 4500 Australian marine fishes – including our 320 sharks and rays.

According to the Australian Bureau of Statistics more than five million Australians take part in recreational fishing in Australia as a leisure activity.
There is also a large commercial seafood and aquaculture industry which is worth over $2 billion annually and employs around 16,000 people.
Combined with the number of people who love a good feed of fish, there are a lot of people with a direct interest in the oceans and seas of Australia and what is in them.

Some researchers have found a way of depurating oysters so that the remaining bacterial counts in the oyster is minimal, and without sacrificing taste, texture and health of the oyster.

The process involves chilling the water to between 45 and 55 degrees Fahrenheit and sterilized it with ultraviolet light. Their method eliminated 99.9 per cent of the bacteria after four to five days. The oysters stayed alive during the purification, and their texture and taste were not altered.

Why shellfish can become deadly

AN adult oyster filters and cleans up to 190 litres of water a day.

They swallow algae, and remove dirt and nitrogen pollution.

Sometimes during the filtering process, bacteria can trigger norovirus which remains in the oyster.

Eating shellfish infected with a norovirus can lead to food poisoning with vomiting, diarrhoea and abdominal pain.

Noroviruses are the most common cause of viral gastroenteritis in humans.

The disease is usually self-limiting and severe illness is rare but it can lead to blood infections of people with compromised immune systems – especially those with chronic liver disease – and can cause severe and life-threatening reactions.

In commercial aquaculture operations, the temperature to maximise growth is around 27-30°C. But what’s their tolerance limits? And what happens in their natural settings?

In this handbook – Schipp, G, Bosmans, J & Humphrey J (2007) Northern Territory Barramundi Farming Handbook. Third revision. Northern Territory Government. – under 2.5 Environmental requirements, it states that “Barramundi fingerlings are known to survive in water… temperatures up to 35°C. They can also survive temperatures as low as 16°C.”

In this factsheet – Q. Allsop, P. de Lestang, R. Griffin and G. White, (2006) Barramundi – Your Questions Answered. Fishnote, No 27, DPIFM – it states that “Barramundi inhabit areas where the water temperature ranges between 23°C to 35°C, from the Ashburton River in the west to the Mary River in Queensland.”

In a dry season day, the ambient temperature in Northern Territory can fall to 15°C and the water temperature in barramundi farms in can drop to around 20°C.

I have had a case where a client with aquaponics setup saw their fish become sick in the middle of May in Perth, when water temperature ranges dropped to as low as 13-17°C. In another case, a barramundi in an outdoor aquarium became ill during the month of July in an unheated outdoor tank.

My colleague’s experience is that the water temperatures in barramundi farms get down to 15°C most years without mass mortality. Two years ago, in dams located in Queensland, water temperatures dropped to 11°C (which was extreme), and it was then that it caused mass mortality.

So, based on a combination of literature reviews of natural occurrences, experimental data and professional experience, the optimal temperature range for barramundi is between 25-30°C. The tolerance range for them would 16-35°C.

Here we should make a distinction that tolerance range means that they can survive this, but only for short periods and only if exposed to the extremes gradually.

This live event is free of charge.

We did a total of 2063.7 km, north of my base in Perth, WA. That’s a lot of road covered!

I got to see dolphins, dugongs, sea turtles, sea snakes, sharks and more! On the terrestrial front, some kangaroos, emus, pelicans and others.

Locals no longer stop to drink the water or swim at Hanrahan’s Creek. The water is freakish green and blue.

The copper concentrations they measured were about 377 milligrams per litre, where a pristine or high conversation stream would be about 0.001 milligrams per litre.

When Redbank Copper acquired the mine in 2006 (some ten years after it was closed) it inherited legal responsibility for the environmental problems. The company is currently attempting to raise $7.5m from investors, arguing that the only way to correct the problems is to restart the mine.
