Q: Where do fish go to get some handy work done?
A: A watershed.
Stressed-Out Tadpoles Grow Larger Tails to Escape Predators.
Tadpoles are commonly used in school classrooms to teach us about growth, development and the environment. Did you know that you can tell a lot about the tadpole’s environment just by looking at their tails? This report concludes that stressed tadpoles have shorter and taller tails.

Are you thinking of having your own backyard aquaponics?
I learnt a thing or two about aquaponics by building my own and after attending an aquaponics conference in Hawaii last June. I learnt that five Australian cities occupied the top six positions in keyword searches for ‘aquaponics’, followed only by Honolulu. These cities have a keen interest in leading the way towards creating sustainable food production with minimum carbon footprint. This is truly an excellent way to grow vegetables and fish, and at the same time, recycle the water over and over again.
After examining many commercially available and backyard aquaponics setups, I have learnt that many aquaponics systems do not cater for the needs of fish. The Fish Vet’s system puts the health and welfare of fish at the forefront and yet does not compromise the productivity of plants.
The stand alone system is fully self-contained, is environmentally friendly and has a low carbon footprint because it is made partially from recycled materials. It is truly self-sufficiency made simple.
The system can also be customised to suit your needs.

Ball tearing, ball busting, testicle biting fish!
It’s the pacu and apparently they may be lurking in a river near you!
Why do people inject carbon dioxide in aquaria?
This is a good paper supporting the reason why some of us just can’t seem to get our plants to flourish, and why some aquarists who are into their planted tanks use carbon dioxide injection (provided that plant nutrients are also available [fertilizers and trace minerals]). So, if you want a beautiful underwater garden, you’ll need to invest in a carbon dioxide injection system.

Fish Joke for Monday-itis: Crossing the road.
Q: Where do Danios cross the road safely?
A: At the Zebrafish crossing.
More insight into the class action brought against the government mishandling of the abalone viral ganglioneuritis (AVG) outbreak in Victoria.
Once the virus was detected, abalone licence holders saw their catch drastically drop by as much as 90%. The virus-affected area accounted for approximately 32% of Australia’s abalone exports before the outbreak.
The claimants to the class action are seeking compensation for damages and losses suffered because of the outbreak of the virus, which allegedly caused a reduction of the permitted annual abalone harvest quota, decreased abalone sales, and reduced profits and the value of holding an abalone licence.
The Victorian Government has declined to comment, saying the matter is now before the courts. However, at the time of the outbreak of the virus, the current Victorian Premier, Dr. Denis Napthine, accused the then Labour Government of an “absolute failure” to control the epidemic. Dr. Napthine compared the epidemic to the foot-and-mouth disease of the abalone industry. He also pointed out that it would take as much as 10 or maybe 15 years for the industry to recover from this virus. Experts, however, cannot predict if and when abalone will repopulate to the point where the industry will recover.

10 American Foods That Are Banned in Other Countries… Why was salmon listed as #1?
I was recently forwarded this scaremongering email and my reply was….
“This is another non-factual email that’s doing the circuit. After reading the first bit about the fish, I decided to stop reading.
Salmon is currently being imported to Australia, but only as frozen commodities due to the risk of introducing exotic biological agents.
Astaxanthine is a phytochemical, not a petrochemical. It’s natural and has anti-oxidative properties and plays a role for UV protection for developing salmon eggs. Many of the grains we ourselves eat at genetically modified. The use of pharmaceuticals in food production animals are highly regulated, because they are the same drugs used to treat human conditions. They are only used when it is necessary, they have to abide by witholding periods and they must be used under veterinary prescription.”
You can have a read for yourself and tell me what you think…

Americans are slowly waking up to the sad fact that much of the food sold in the US is far inferior to the same foods sold in other nations. In fact, many of the foods you eat are BANNED in other countries. Here, I’ll review 10 American foods that are banned elsewhere, which were featured in a recent MSN article.
Seeing how the overall health of Americans is so much lower than other industrialized countries, you can’t help but wonder whether toxic foods such as these might play a role in our skyrocketing disease rates.
#1: Farm-Raised Salmon
If you want to maximize health benefits from fish, you want to steer clear of farmed fish, particularly farmed salmon fed dangerous chemicals. Wild salmon gets its bright pinkish-red color from natural carotenoids in their diet. Farmed salmon, on the other hand, are raised on a wholly unnatural diet of grains (including genetically engineered varieties), plus a concoction of antibiotics and other drugs and chemicals not shown to be safe for humans.
This diet leaves the fish with unappetizing grayish flesh so to compensate, they’re fed synthetic astaxanthin made from petrochemicals, which has not been approved for human consumption and has well known toxicities. According to the featured article, some studies suggest it can potentially damage your eyesight.
Where it’s banned: Australia and New Zealand
How can you tell whether a salmon is wild or farm-raised? The flesh of wild sockeye salmon is bright red, courtesy of its natural astaxanthin content. It’s also very lean, so the fat marks, those white stripes you see in the meat, are very thin. If the fish is pale pink with wide fat marks, the salmon is farmed.
Avoid Atlantic salmon, as typically salmon labeled “Atlantic Salmon” currently comes from fish farms. The two designations you want to look for are: “Alaskan salmon,” and “sockeye salmon,” as Alaskan sockeye is not allowed to be farmed. Please realize that the vast majority of all salmon sold in restaurants is farm raised.
So canned salmon labeled “Alaskan Salmon” is a good bet, and if you find sockeye salmon, it’s bound to be wild. Again, you can tell sockeye salmon from other salmon by its color; its flesh is bright red opposed to pink, courtesy of its superior astaxanthin content. Sockeye salmon actually has one of the highest concentrations of astaxanthin of any food.
“Don’t dump that fish” – keep aquarium fish where they belong
This is an article by the Department of Fisheries
The Department of Fisheries’ "don’t dump that fish" campaign was launched in October by Western Australia’s Chief Scientist Professor Lyn Beazley. It is part of the Department‘s program to improve the State’s aquatic biosecurity defences.
The campaign is supported by the Department of Agriculture and Food, the aquarium industry, and the Perth Cichlid Society. It is designed to raise awareness of the impacts of releasing unwanted aquarium fish, snails and plants into waterways, toilets, drains or the ocean. It will also provide advice on how to responsibly dispose of such unwanted pets.
To help spread the word, "don’t dump that fish" posters, brochures and fish bag stickers have been produced for aquariums retailers around the State.
“The wider community is a huge resource in the fight to prevent aquatic pests entering and establishing in WA. Industry-supported programs, such as this ‘Don’t dump that fish’ campaign, are powerful ways of engaging many people on aquatic biosecurity issues,” Professor Beazley said.
“With millions of fish being transported around the globe, importation of aquarium fish is potentially a major source of invasive species.”
“Given the difficulties in eradicating pests once they are established, the Department’s focus is on prevention by ensuring key stakeholders, such as the ornamental fish industry, have access to relevant information,” she said.
“Fish owners who no longer want their fish are encouraged to give them to other responsible owners or an organisation with an aquarium, or to seek advice from their local pet shop.”
“If you are unable to find a new home for your fish, or if the fish are sick or diseased, please dispose of them responsibly and humanely.”
Advice on how to dispose of them is included in the new brochure, which can also be found on the Department of Fisheries’ website at www.fish.wa.gov.au/biosecurity or visit www.kb.rspca.org.au and search using the term ‘humanely euthanase fish’.
Sightings of suspected aquatic pests should be reported to the department’s FISHWATCH service on 1800 815 507, or via email to biosecurity, or through the free WA PestWatchapp, which can be downloaded from the App Store and Google Play Store.
