Wild stingray encounter marred by reef fish decline

Australia's south west offers a little-known wildlife experience that's hard to beat. At Hamelin Bay near Augusta huge wild smooth stingrays and eagle rays regularly come to the beach to be hand-fed by eager visitors.

Possibly unique in Australia, this behaviour began in the 1950s and 1960s when commercial fishermen cleaned their catch offshore. Today a fish-cleaning table for recreational anglers provides a seemingly endless supply of offcuts for the visiting rays.

For the marine conservationist this creates a dilemma. Many reef fish species caught by the anglers are in steep decline, so in the process of having a once-in-a-lifetime experience you may also be indirectly contributing to the ruination of Australia's offshore reef ecosystems.

The overfishing of large reef fish has caused stocks to crash worldwide, and recreational angling is a significant contributing factor. Many reef fish species are long-lived, slow-growing and only present in relatively small numbers. Even moderate fishing pressure can have a dire effect. Add to this the lack of sufficient marine protected areas, inadequate fish stock assessments, and the outlook for fish like the western blue groper is bleak.

The rays themselves, which generate significant tourist income, have absolutely no legal protection. In January 2011 two young fishermen speared and butchered a tailless stingray nicknamed 'stumpy' in front of horrified onlookers. A plan to offer the rays more protection was drawn up in 2006 but is still awaiting approval. This lack of legal protection combined with the decline of reef ecosystems due to overfishing may see the end of the visiting rays and the priceless wildlife experience that they provide.

Update: Since this blog was written the Hamelin Bay rays have been given limited protection in the vicinity of the beach.

Thousands rally against shark cull in Western Australia

Upwards of 4,000 people gathered on Cottesloe Beach, Perth, Australia today to rally against the upcoming cull of sharks by the Western Australian government. Similar events were held all over the country including New South Wales and Queensland, both of which have been culling sharks for decades.

Passionate speeches were made by representatives of West Australians for Shark Conservation, Conservation Council of WA, Sea Shepherd Australia, WA Greens, and the Australian Labor party.

Speakers emphasised that proper research is woefully lacking, the cull will damage the marine ecosystem and the indiscriminate killing of sharks and associated bycatch was a poorly considered, knee-jerk reaction by the WA government. Similar shark culls have been tried elsewhere in the world and failed to reduce shark-related fatalities.

Public awareness of shark conservation is making great strides - a gathering like this would have been unheard even 20 years ago - but as the politicians in the WA government are proving, there's still a long way to go.
