The High Price of Peace of Mind

We Aussies love our beaches – in the warmer months the coastline has a magnetic pull, drawing us to the sand, sea and surf in our thousands.

But while the thought of a refreshing ocean dip might be appealing, the concept of potentially coming face to face with one of our most feared predators has prompted officials to take drastic action.

Shark nets have been deployed off the shoreline of the east coast for more than 80 years.  But they offer a false sense of security.  Stretching less than 200 metres long and extending down only 6 metres, these mesh barriers are at best a deterrent and certainly don’t make beaches attack proof.

Sharks can get under, over or around them, and as it turns out, more are caught on the shore side of the net when they’re heading back out to sea, than when they’re swimming towards shore.

The holes in the mesh are around 50 centimetres across – large enough to let small animals pass through, but the perfect size for trapping bigger species.

Turtles, dolphins and rays are common victims of the nets – becoming entangled and drowning or starving to death.  A major concern is the ensnaring of humpback whales on their journey back to Antarctica after their annual breeding season in the tropics.

Calves in particular are easy prey – in just over a decade 55 have been caught in the shark nets, including one off Noosa in late September this year.  Another swam down to Sydney with the remnants of a Queensland net still wrapped around its mouth.

But the toll on the animals targeted by these barriers is far greater. In 2017 alone, more than 500 sharks were caught in the nets off Queensland – 377 died, more than 100 others had to be euthanised – only 20 were released.

Amongst the victims were grey nurse sharks which are classified as critically endangered and pose no real threat to us.  The vast majority of species share the sea quite peacefully with people – only a handful of sharks are responsible for fatal attacks on humans.

Just to put it all into perspective, on average one person a year is killed by a shark in Australia, as opposed to 5 dying from falling out of bed, 10 struck down by lightning or perhaps the most sobering, more than 1,100 taken on our roads.

Shark attacks are extremely rare and there is no scientific evidence to prove that nets protect humans.  What we do know is the attempt to keep us safe is killing marine life indiscriminately.

Removing so many animals, including apex predators, will have an impact on  local marine ecosystems – but we won’t be able to calculate that cost until far too late.

Marine biologist, Holly Richmond, feels so passionately about the need to remove all nets, she’s created a video:  www.thesharknetfilm.com

Ocean Life Education is passionate about protecting all marine animals and focusing on the important role sharks play in our oceans.  For more information about our programs including our Shark Discovery presentation visit: https://www.oceanlifeeducation.com.au/programs/

 

Celebrating SeaWeek

There is one time of the year we look forward to more than any other at Ocean Life Education – when collectively as a nation, we take the opportunity to pay homage to the sea.

SeaWeek is Australia’s major public awareness campaign centred around our oceans – a chance to turn our attention on what the water does for us and what we in turn can do for it.

This year’s theme was ‘The Ocean made Earth Habitable’, focusing on how the majority of oxygen in our atmosphere has been produced by microscopic sea creatures during photosynthesis.  Thanks to their contribution over thousands of years, life on land was able to develop.

And the impact is still ongoing today – with more than 70 percent of the planet covered in water, it plays a major role in many aspects of our daily lives.

Australia has one of the largest ocean territories in the world – it drives our climate and weather and provides valuable resources. Marine animals and plants are found in medicines that are used to fight cancer, arthritis and heart disease.

On average, we each consume around 25 kilograms of seafood every year, harvesting more than 150, 000 tonnes of fish annually.

Eighty-five percent of Australians live within 50 kilometres of our vast shoreline – drawn to the water not only for food but fun as well. We have 10,000 beaches spread around our 50,000 kilometres of coast and almost 3 million of us own a boat allowing us to explore beyond the shallows.

But as we become more globally aware of climate change and the impact our modern lifestyle is having on the oceans, it’s time for us to breathe new life into the part of our planet that made all of this possible in the first place.

Ocean Life Education is dedicated to promoting the preservation of our marine environment.  Our Human Impact Program takes a close look at the effect we have on the world’s waterways and, most importantly, how we can make a change for the better to sustain our seas for generations to come.

Ocean to Outback – Sights, Sounds and Smells of the Sea Go Bush

Considering they’re very basic creatures, sea stars have some pretty amazing abilities (like regrowing their own leg if they lose one!) but they don’t normally travel hundreds of kilometres inland… until now.

With a little assistance from Ocean Life Education, our Blue Linckia’s, along with the rest of our marine life menagerie, have temporarily migrated away from the coast to help students who rarely get to see the sea understand more about the challenges these animals face.

In a road trip lasting 3 days and covering close to 500 kilometres, Ocean Life Education is making sure children in Blackbutt, Nanango and Kingaroy don’t miss out on the chance to touch and learn about our wonderful animal ambassadors.

The Ocean to Outback initiative is supported by the State Government through its Advance Queensland Engaging Science Grant.

Why go to such extreme lengths to facilitate these encounters?  Oceans cover almost three quarters of our planet and produce more than half of the oxygen on earth while absorbing harmful carbon dioxide.

Ocean currents also move such a large body water between the equator and poles, they help to regulate the global climate which impacts all of us – even those that live well beyond the shoreline.  Keeping the oceans healthy is in everyone’s best interest.

But travelling with a crew of sea stars, sea cucumbers, sea urchins, hermit crabs and a shark is not without its challenges as water quality and oxygen levels are vital to their survival, especially in the hostile bush environment.

One thousand litres of salt water have been transported along with the animals to ensure they are stress free on their little adventure.

But all the planning, all the logistics have been worth it just to see the excitement on the faces of a whole new batch of ocean lovers, who may rarely hear the waves crash or smell the salt in the air but know the importance of caring about the underwater world – even this far from the coast.

Marine Biologist for a Day

Over the past few years, hundreds of primary schoolers have enjoyed our holiday sessions that inspire them to care for the ocean – now it’s time for the high schoolers to get in on the action.

Due to popular demand, our Marine Biologist for a Day program has been adapted to cater for an older audience who want a more in depth look at the world of marine science.

Students will have the chance to examine in detail our impact on the ocean including environmental stress on coral reef systems, water acidification and plastic pollution.  We will discuss a wide range of ideas on how to better care for the health of our seas.

The aim of the program is to making learning fun and relevant, examining animal classification to discover how each creature fits into the aquatic world.

The program will be very interactive, with students observing the dissection of a dead fish to reveal the organ make-up and development of a mullet.

And our most popular feature will still be included – the chance to gently touch our living sea creatures – an opportunity that never gets old at any age!

This program will provide a valuable insight to the workings of the aquatic world for any high schooler who has a passion for the ocean or is considering a career in marine sciences.

But we haven’t forgotten the younger students – our classic Marine Biologist for a Day will still be running in school holidays – we’re just expanding the program to grow with your kids.
