GSR enthusiast and diver here. Great videos. Ive been telling people lately to think of places other than the GBR to dive. Because NSW, VIC, SA and WA really do have excellent dive sites. Recently ive been diving Edithburgh and Rapid Bay, and they are world class.

Beautiful fish and species, how is its age established?
@GreatSouthernReef 23 күн бұрын
Using Otoliths (ear bones) of the fish! They grow in layers over the fish's lifetime, similar to the rings in a tree trunk. Each ring represents a growth period, often correlating with a year, making it possible to estimate the age of the fish by counting these rings.

How about eating the sea urchin roe? There is a whole industry in many nations (Japan, Chile, etc.) that thrives on this product. The article seems rather incomplete without further analysis of the options available.
@GreatSouthernReef Ай бұрын
Hi thanks for your comment. We are currently working on a documentary about the urchin situation in Australia (stay tuned!). Indeed the roe is a delicacy sought after by many cultures. Australia has a fledgling urchin industry that needs further development and investment. Harvesting and processing is expensive and time consuming. Also, the urchins that come from barrens often have poor roe quality, another challenge. Furthermore many of the urchins are in remote and deep reefs. There are viable solutions and plans to implement, but the situation requires federal funding and investment.

What is the light source in the video? Is that from the camera or bioluminescence?

There are also lights mounted on the underwater camera which is attached to the sealion!

It's too bad they can't import some sea otters. They'd take care of all those urchins.

We had a similar problem with urchins decimating the kelp forrests off Palos Verdes, California.

Thanks for commenting. We have urchin divers in Aus., the issue is the processing at the moment. The catch of one diver in 3h (filling a boat) will take 15 people about 8h to process!

I witnessed the decline of the kelp forrests off Palos Verdes, California, where I grew up diving. They became aquatic deserts covered in purple urchins for sometime, but now the kelp, and the diversity has come back in many areas.

IPCC Chapter 11 Loss of kelp forests in southern Australia and southeast New Zealand due to ocean warming, marine heatwaves and overgrazing by climate-driven range extensions of herbivore fish and urchins. For example less than 10% of giant kelp in Tasmania was remaining by 2011 due to ocean warming (high confidence). {11.3.2.1, 11.3.2.2}

How did you manage to mount the camera on it? However, it seems to me that the light from the camera annoys the sea lion?!

8/7 NY Times ran a story. camera afixed to wet-suite type rubber size of credit card which was glued to sleeping (drugged) animal. 2 days later, when they returned to the pups, the cameras were removed. The rubber will fall off when the animal sheds its fur. The "however"? At 300 feet, if these went that low, maybe the light helped. Let me know if this helped (2 weeks later.)

"due to climate change... ...they're becoming extinct before we even know that they're there." Wow. Climate change is so powerful it's doing stuff we don't even know that it's doing. How do we know? We don't, we just know. That's climate change in a nutshell.

There has been a trial introducing more of the natural predators (rock lobsters in this instance). However urchin numbers seem way too high (20M+ in Tasmania alone) to be controlled effectively by urchins.
