South Australian Beaches are Ecologically Toxic

Dead fish on South Australian beaches gives bad conservation image.

When marine animals wash up on the shore dead what does a state government do about it? It tries do deny it and cover it up! Maybe it will stop in time - unfortunately it continues. The thousands of small fish dead on the beaches are bad enough, but dolphin corpses are found as well, even some penguins.

The location is on the South Australian coast near the Port River, Adelaide. Recently, a grieving female dolphin was seen nuzzling her dead baby, a terrible sight. A concerned PHD student, Nikki Zanardo, is investigating the issue. There is a worrying mystery here. Why has the state government sent dolphin samples to New Zealand? Tests could have been done in South Australia. If herbicides or industry poisoning is at fault, it will all come out eventually. You cannot hide anything today.

It is not right that consumers are allowed to eat seafood when there is a possibility that dangerous biological toxins are the cause. If dolphins can die so can humans. We are both mammals after all. Apparently test results will take up to a month. Tests should be done on fresh fish at the markets immediately to make sure it is safe to eat. The South Australian government will be liable in the event of a medical emergency.

Ships' Ballast Water Spreads Marine Creatures

As international trade continues so does "equalization" of the planet. Many marine species are now found in all waters of the world. This is because transport ships literally hoover up animals in ballast water, which is released at any time, any place, when it is no longer needed.

All ballast water is released into a port when cargo is taken onboard. Marine survivors of this rough treatment give the local environment a go. Some are successful and multiply to epidemic proportions. Zebra mussels and Pacific seastars in particular are a major problem.

An Australian study gathered data such as ports where ballast was likely to be taken on and where it would probably be released. Marine species spread this way were identified and it was predicted how long they would survive. This data was fed into a computer.

It was noticed that shipping volume was increasing mainly in the transport of primary products. Most of this Australian export was delivered to Asia and Southeast Asia. This meant that marine species from this region were unloaded into Australian waters.

New laws were introduced in 2001 to ban the emptying of Asian ballast water into Australian seas. The new rules have been totally ignored. Furthermore, the International Convention for the Control and Management of Ships' Ballast Water and Sediments (BWMC) directed ballast water be unloaded into holding tanks. Shipping is not complying.
