Recovery of Sharks within a well enforced MPA - Paper!

Very nice - watch!

Paper here, synopsis here.
I must say that contrary to other papers looking at different aspects of those reefs off Western Australia where I am weary of some of the conclusions, I am quite impressed by this one as the evidence for the rapid recovery of those Sharks appears to be rock solid as e.g. evidenced by the video below.

This is good news indeed.
Provided that there is strict enforcement, MPAs appear to be an effective tool in the protection of at least those comparatively less migratory coastal Sharks - and if so, there is certainly reason for hope.

Of course for us this is nothing new.
But good to see our data (and here!) confirmed by research from other parts of the word.

Enjoy the paper!

Gallivanting Tiger Sharks - new Paper!

Remember this post?
Sure you do! :)

Now, check this out.
Once again, this is evidence for the massive influence of environmental factors whereby both the coastal abundance and swimming performance of those migrating Tiger Sharks are being shown to be highest at ~22°C. Consequently, they track their optimal temperature and are thus more likely to be found in coastal areas in winter in the tropics; but towards temperate latitudes, they are more likely to be found in coastal areas in summer, see the figure at the top - and as climate change continues to heat up the oceans, those tracks are likely to shift poleward with according potential consequences for coastal communities, see the example of Sydney.

Very interesting!
Incidentally, this is very similar to what we are currently experiencing with our Bulls who have been shown to favor a temperature of ~26°C.
As the water temperature at Shark Reef has recently hovered around 29°C for a protracted period of time,  the number of especially the larger Bull Sharks has been appreciably lower - and whereas we don't dispose of any strong evidence, it is only fair to speculate that they may have retreated to greater depths or even absconded to places like Kadavu where the water temperature has been significantly lowered by Gita.

But I'm digressing as usual.
Great paper featuring numerous people I like and respect.

Bull Shark Tagging in Fiji!

Very nice!

Check this out.
Pascal was here to assist Kerstin in catching and tagging neonate Bulls. And whilst she has been concentrating on the Rewa River where she has managed to bag more than 100 pups, he and Gauthier of Projects Abroad did fish in the Sigatoka - not as productive as the Rewa but in exchange the results have been  very interesting indeed!
And whereas I'm not at liberty to elaborate quite yet, I can reveal that they will most certainly become an integral part of an upcoming paper, so keep watching this space!

Anyway, lovely post!
And I had to chuckle at the typically Swiss polite reference to cultural challenges = the usual shenanigans where the locals will always try and test any newbie!

Escape to Shark Reef!

Very nice!

Check this out.
Juerg has been the scientific supervisor of our research and conservation for 15 years, and we simply could not be happier with the friendship, the level of cooperation and the many stellar papers our symbiotic relationship has spawned.
Contrary to what some self-appointed literal saviors of Fijian Sharks may want you believe, this is by far the most comprehensive and important collection of Shark research papers in Fiji. As such, it already has and continues to inform Government about sustainable Shark management, Shark conservation and sustainable Shark ecotourism.

And of course this is not the end by far!
As I consult my notes, there are several papers in the pipeline, some of which in preliminary stages all the way to some that are in final review and will be published very shortly indeed.

Keep watching this space!
