Presenting one chapter of my PhD today for @world_fisheries. Tune in to hear about some of the awesome work on non-target species we have been completing 🐟
On now @JDennis_Sci presentation for @world_fisheries Are non-target species affected by wildlife tourism. Find out today By-catch, habitat, depredation (03) 11 am - 12.45 pm

Very excited to have our paper published in Fishery Bulletin!
Non-sharky paper for something different: otolith chronology of 2 small pelagic fish species led by @JDennis_Sci with @Jon_Smart1 #GretchenGrammer @HuveneersSSEG #TimWard @SA_PIRSA @FlindersMarine

Otoliths are useful tools for studying growth in #fish: the latest paper from @SouthernSharkEG, led by #PhDstudent @JDennis_Sci, looked at how they can be used to study #environmental drivers of growth in common jack mackerel and redbait. Check out their findings below!

Success! All receivers recovered and re-deployed for another year of VPS array at the Neptunes Islands monitoring white sharks, kingfish, and trevally @SAEnvirWater @FlindersMarine great job by all @SouthernSharkEG students. Thanks to @IMOSAnimalTrack @vemcoteam for support

Not the typical environment for a conference, but a great virtual talk nonetheless! Well done @JDennis_Sci on your presentation looking at different methods to measure abundance of trevally for the 2020 @AustSocFishBiol conference!

Happy to tick off my first milestone, stay tuned for exiting things to come
There is a lot of research on wildlife tourism but non-target species are often forgotten. @JDennis_Sci gives us an overview of his PhD on trevally (Pseudocaranx app.) at the Neptune Islands @SAEnvirWater

Thanks to the production team which supported several research projects during the filming of the white shark segments including projects of @Meyer_Sci @Maddie95_ @TMClarke95 @JDennis_Sci
Great documentary on @natgeoau tonight by #ThisFilmStudio with Mick Fanning learning about #SharkScience from @SharkColin @DrNeilHammer @BrendanKelaher & @SouthernSharkEG

One year down for the PhD, and a full year of trevally detections in the bank, excited to see what the data shows!
100% recovery thanks to @Innovasea VR2AR and @IMOSAnimalTrack Recovered, downloaded, serviced, and redeployed for another year of acoustic monitoring of white sharks, kingfish and trevally @IMOS_AUS

This clip highlights a question asked by @Meyer_Sci from the @SouthernSharkEG in one of her recent publications on how wildlife tourism provisioning affects non-focal species. It’s a very interesting study. Have a read at the link below. https://t.co/pZUO45b81w

Eerily quiet airport this morning... quite fitting for a field trip to download @Innovasea receivers to look at the effects of reduced human activities during COVID-19 restrictions on animal movements

@ShalyahEvans 👍 #AbandonedWaters recap 1. also featured @Maddie95_'s #shark deterrent research. Yay for #WomenInSTEM 👩🔬 2. correct - no coms just means no chit chat. We usually don't dive w/ coms anyway 🔇 3. The fish are WAY more stressful than the sharks! Subject of @JDennis_Sci's PhD 🐟

An awesome shot of how we test different deterrents around white sharks - using the stereo camera so that we can measure how close the sharks get to the experimental setup. Extra points to whoever can spot a Trevally tagged by @JDennis_Sci.

The end of an era... the lab used as an office space for >5 yrs is finally getting renovated into proper offices. Stay tuned for completed pic in ~4 weeks

A bit late for #SharkAwarenessDay, but I think this octopus was quite aware of this swell shark and tried to have a cheeky nibble. #BRUVS #GreatSouthernReef #TeamFish #TeamCephalopod

Haven’t been to this spot before: Pages Conservation Park. If you zoom in and squint, you can sea the Endangered Australian Sea Lion relaxing at the top of the island. Acoustic receiver recovery time @IMOS_AUS @IMOSAnimalTrack @vemcoteam
