Fish Patterns in the Seasonal Seascape

Freezing waters surrounded by picturesque scenery on a cold (-15°c) winters day in the Gullmarn Fjord, western Sweden. If you look closely in the water, a curious common seal keeps watch.

Tom Staveley is a Marine spatial ecology & PhD candidate at DEEP Stockholm University and he is currently putting the finishing touches on his thesis. Both of us are living the invandrare life in Sweden at the moment so I got a chance to catch up with him recently and managed to drag him away from the thesis for long enough to give us a run down (below) on some of the research he has been working on.

Fish Patterns in the Seasonal Seascape

Being a marine ecologist in Scandinavia certainly has its advantages: long summer days to do seemingly endless fieldwork, stunning surroundings and surprisingly lush underwater habitats (yes, I’m talking mainly about seagrass but we’ll get to that later). Even in the heart of winter a sublimely frozen wonderland of crisp air, still bays and snow-covered land- and seascapes never ceases to amaze. For the past few years, I have been exploring the coastal waters of western Sweden in the Skagerrak/North Sea focusing my research on seascape ecology – a relatively new branch of marine science focusing on broad-scale patterns and processes in the seas and oceans.

Tagging tigers to explore the Green Seas

As expected, the highly anticipated Blue Planet II series has been nothing short of amazing. This week we are incredibly lucky to have a guest post by shark researcher; Samantha Andrzejaczek who helped film the upcoming Blue Planet episode. Sammy is a PhD candidate at the Australian Institute of Marine Science and University of Western Australia investigating the vertical movement of sharks. She also runs a fantastic blog – www.sammyshark.wordpress.com, which we definitely recommend checking out. Read on to go behind the scenes of Blue Planet II. You can watch the episode this Saturday night (17th) on Channel 9 in Australia. Continue reading

Australasian Fishes: We Want Your Fish (Sightings)!

original John Sear 4

Fish Thinkers has just become an official project supporter of Australasian fishes, which as someone that has a slight obsession with fish, I am rather happy about.  Set up by the Australian Museum in 2016, it is a really nice example of a citizen science project that is open to all and it is getting lots of interesting results.

How do patterns in coastal seascapes influence temperate reef fish assemblages?

Daniel Swadling is a new PhD student at the University of Wollongong who is embarking on a project to better understand the relationship between temperate fishes and their habitats. He also loves his luderick and drummer fishing using an old school Alvey reel, so he is going to fit in just fine and I sense there will be plenty of fishing adventures in the future. Below is his guest post recapping his honours project and where he is heading with his PhD research.

My name is Daniel, I am a PhD student at the University of Wollongong (UOW) Continue reading

Top shelf bottom feeders

If you are in Jervis Bay and see someone knee deep surrounded by rays or alternatively sitting staring at rays for hours on end then chances are you are looking at the “mother of rays”  otherwise known as  Joni  – the driving force behind the Stingray Diaries. She’s studying smooth stingrays throughout the Jervis Bay Marine park, in conjunction with Fisheries NSW and gives us a rundown on her research in her guest blog below…

Top shelf bottom feeders

Learning to swim by getting thrown off the end of a busy public wharf on the Hawkesbury River in nothing but a pair of hot pink floaties… Living in a swimsuit and covered in sand every single day of the year… Chucking tantrums when told to come inside after playing on the beach all day because it was dark… At the age of 4, saying with great certainty, “Mum, when I grow up I’m going to be a Marine Biologist.” Continue reading

Baby sharks head for home…

Who says sharks aren’t cute?  Watch this video and tell me otherwise!  And worth a quick blog post surely?

I recently spent a few days running a shark tracking workshop @tarongazoo projectshark in Jervis Bay with @400knots & @kye.adams.  There were various other workshops running too – Including Matts on marinedebris and another on Port Jackson shark ecology and behaviour by Sherrie and Cat from Maquarie Uni together with Sue from crest diving.

After the event I got a chance to race off and film these little sharks getting released back into the wild by Conner who had just arrived from Macquarie Uni Fish Lab.  Research from the lab has shown that when these PJs are adults they will migrate to Tasmania and back again each year! And often return to exactly the same crevice to breed each time!!
