Webinar on Koi Herpesvirus (KHV) as a Potential Control Agent for Australian Carp

This presentation will provide some background information on the epidemiology of the disease caused by cyprinid herpesvirus 3 (CyHV-3), and will then consider the major questions that arise whenever the use of CyHV-3 is promoted as a biocontrol agent, including why it is necessary to control carp in Australia, whether it will be effective and safe to use, and what virus strain(s) will be used.

Presenter: Dr McColl is a veterinarian with training in virology, immunology, pathology and molecular biology. After completing a pathology residency and PhD at Cornell University, he joined CSIRO-Australian Animal Health Laboratory (AAHL) in 1990, and the Fish Group (at AAHL) in 2000, and is involved with KHV research that has been funded by the Invasive Animals of CRC, since 2007.

Who is The Fish Vet?

Dr Richmond Loh, aka The Fish Vet (and sometimes The Fish Doctor), is a fish enthusiast, an aquatic veterinarian and a fish pathologist. He has kept fishes from his early years and continues to do so now, and into the future. His continued dedication to improving the health and welfare of fishes is exemplified by the course of studies he has undertaken and the countless hours of continuing education. He has been providing veterinary services to fish keepers, breeders, retailers, public aquaria, and farmers since 2002, starting in Tasmania. Now based in Perth, Western Australia, his reach is Australia-wide with The Fish Vet representatives in Melbourne, Sydney and Townsville.

Sensible fishing rules.

There’s finally some sense into the fishing rules. Now they’ve introduced bag limits rather than strictly size limits. It takes into consideration that fish may not always be in optimal shape to be released after being hooked. Now I hope this sensible approach can also be used more widely to include other species such as abalone (since most are gauged off rocks [and significantly injured] before they’re measured).

11 Nov 2016 1:43 PM AEST – Simplifying size limit rules for WA fishers

To continue its efforts to reduce red tape and simplify the State’s fishing rules, the Department of Fisheries has undertaken a major review of all finfish size limits across Western Australia.

Policy and Strategic Services Director Nathan Harrison said the review was science-based with the aim of ensuring size limits contribute in a meaningful way to the sustainable management of individual species.

“For example, where there are high rates of post-release mortality due to barotrauma, it is proposed that the minimum size limits be abolished for a range of species, such as baldchin groper and breaksea cod,” Mr Harrison said. “Reducing mortality rates offers sustainability benefits.

“In addition, where fish are often not retained or targeted as sports fish, the proposal is that minimum size limits are removed for various species, like Australian salmon and Samson fish.

Mr Harrison said size limits for finfish would remain, where they were necessary to ensure ongoing sustainability for species that needed a range of management measures to help protect them from exploitation.

“Where possible size limits have been simplified and standardised for many commonly caught species,” he said. “This is a win–win outcome for both fishers and sustainable management.”

Mr Harrison said the Policy on the Application of fish size limits in WA, which was now available, was developed after requests from Recfishwest and WA’s Fishing Industry Council.

“The new policy will now provide a framework for applying size limits,” he said.

“This policy was used in the development of the second document being released today for public comment – A review of size limits for finfish in WA.”

Details of how to make a submission during the six-week consultation period, which will close on 23 December 2016, are available on thePublic comment page atwww.fish.wa.gov.au.

Given the public consultation period, related to the discussion paper, as well as required regulatory processes when decisions are finalised, formal arrangements to implement size limit changes are not expected to be in place before early to mid-2017.

More information on the current recreational rules, including size limits, is available in the currentRecreational fishing guide 2016 or atwww.fish.wa.gov.au, or collect the guide from departmental offices, orInformation Outlets.

Implications of Change of Weather on Outdoor Ponds

To fellow owners of outdoor ponds,

Have the algae in your ponds proliferated over the last 2 days with the warmer temperatures? If they have, please read on!

It is forecast to be cloudy tomorrow with a maximum temperature of 22 degrees Celsius, a drastic drop from the last 2 days. Warm, sunny weather taking a turn for cooler, overcast days may spell trouble for pond fish. The weather can change the dynamics of your pond’s ecosystem.

Algae require sunlight for photosynthesis (the process of making their own food and releasing oxygen as a by-product). But with cloudy days, algae are not able to perform this but instead undergo respiration (consuming oxygen and producing carbon dioxide, like you and I when breathing). Oxygen may become depleted in the pond resulting in fish deaths.

To complicate matters, algae tend to die during such changes in weather, and the resultant decomposition eats up even more oxygen from your pond.

To overcome this, provide more aeration to your pond to increase its oxygen level. This can be in the form of more airstones, fountains, waterfalls, or any other means of physically moving water around. Use of algaecide is not advised at this time because this further compounds the matter by killing the algae leading to decomposition and the consumption of oxygen in the water. Avoid feeding your fish for the time being, or feed them minimally until good water quality parameters are restored.

Thank you for reading and remember to "pump up" the aeration!

The above was prepared by our final year veterinary student – Ivan Lim, with thanks!
Who knew he was so punny!

Whacky weather with high and low temperatures.

Two days of warm followed by cold…
This will wreak havoc with fish health.

Those rearing rainbow trout will need to harvest their fish today, if their water temperature approaches 23 degrees Celsius or higher. They are cold water fish and can’t tolerate high temperatures.

Those with outdoor ponds will need to improve water quality conditions and add vitamin C to their water to help boost their fish immunity. The fluctuations in temperature is stressful for fish. On Tuesday, consider adding salt to the pond at a rate of 2g/L.

Those with axolotls need to invest in a chiller for summer, putting them in the refrigerator (set 8 degrees Celsius) as a temporary measure.

Should fish be treated prophylactically?

For new arrivals, it’s almost always a YES. There’s never a guarantee you won’t bring diseases home. In fact, this is the most common way diseases get around. It’s always "buyer beware!"

How about resident fish? Should they be treated annually or biannually? If you don’t have issues and never have, then there’s no reason to expose fish to these poisons.

However, if parasites like Dactylogyrus or Capillaria have been diagnosed, and because it’s difficult in some instances to eradicate, then possibly YES, to prophylactically treat when fish show first signs of illness. To simply treat on a calendar schedule will lead to drug resistance.

We reveal why the microscope is such an important tool to diagnose fish diseases.

The microscope is such an important tool to diagnose fish diseases. So many fish parasites are invisible to the naked eye. Fish show such a limited range of clinical signs of illness that it’s impossible to differentiate between the many diseases. Successful treatment of fish diseases begins with having the right diagnosis.

In this video, I demonstrate how to use one, how to prepare samples from fish, and what parasites you can see, to get you on the right track for successfully treating fish ailments.

But if you still think it’s too complicated, don’t want the expense of buying your own scope, and prefer a fish veterinarian to diagnose your fish disease/s, then here is an alternative.
