Wishing you calm seas @alltooclearfilm.bsky.social! In partnership with @harknesslab.bsky.social and @lakeheaduniversity.bsky.social, we will be sinking an autonomous up-looking echosounder that will ping 24/7 to help understand the diel behaviour of fish and zoop at Sup Shoal. Be sure to tune in!

Lake Simcoe never disappoints- lots of prey fish to see with our echosounder tonight. #LakeSimcoe

Beautiful morning to be out pinging in Parry Sound (Georgian Bay, Lake Huron).

Many reasons why the feds need to keep science staff. Invasive species & water know no boundaries. The quagga mussel is in at least 17 states & Canada. There needs to be strong cooperative programs & research to deal with invasives. 🌊🌊 @alltooclearfilm.bsky.social www.wpr.org/environment/...

📣 TWO WEEKS UNTIL WE STAND UP FOR SCIENCE! 📣 On March 7th, we’re Standing Up for Science in DC & ALL 50 STATES to make our voices heard. We hope you’ll join us! ☀️ #sciencenotsilence #scienceforall #standupforscience2025

It is tough to do sea lamprey control in the US waters of the Great Lakes when front line control agents are fired. Just one of the consequences associated with random terminations of environmental professionals in the US. www.bridgemi.com/michigan-env...

Wanna learn more about what we do? Have a look at some of the #hydroacoustic services we provide. Our promo doc includes clickable links to videos, echograms, case studies and examples. Thx for check'n it out! 📌 www.milnetechnologies.ca/MilneTech_Do...

Yesterday was our final day of tagging spawning lake whitefish on Lake Simcoe. We will be tracking the movements of these fish around the lake.

Are you a fish telemetry practitioner? The 7th International Conference on Fish Telemetry will take place June 8-13, 2025 in Traverse City, Michigan, USA. The conference website is now live for abstract submission and details on the venue. Help spread the word. event.fourwaves.com/7thicft/pages

Very happy to share our new paper (also my 1st, first-author pub!), which is the result of several years of relationship building, planning, adapting, learning, and reflecting amongst an incredible collaborative team. So awesome to see it out in the world! www.facetsjournal.com/doi/10.1139/...

Just for fun, here is the echogram video for Lake Trout Tag ID 4 from Fig 6 panel b. Note the Cisco school displaying "Fountain Effect" upon Lake Trout attack from below. Super windy day so hope video doesn't make you feel too sea-sick!

The video animated from Fig 6. We found that Lake Trout are often "pack hunters", displaying coord'd attacks on Cisco schools from below. Obs attack speeds >3 m/s at 5 m from school! The #sonar tag detection tool could track the fine-scale movements of individuals and map out their prey fields.

#ThrowbackThursday; this one from 2007. Tracking tagged (and untagged) Lake Trout using multibeam #sonar and 200 kHz #acoustic tags. 3D model from "Tag01" in TAFS paper by @airydunlop.bsky.social , @harknesslab.bsky.social , @echoview.bsky.social , et al. doi.org/10.1577/T08-... #hydroacoustics

This was a cool study and fun paper to write. We followed acoustically tagged lake around with a multibeam sonar to study their behaviour. Observed attacks on prey fish schools and interactions with other lake trout.

DYK the fish can hear you coming? We tested the effect of outboard engine noise on the distn of fish targets within the #acoustic beam of a split-beam echosounder. Small-boat #hydroacoustic surveys of @iisd.bsky.social ELA LK224 were run with either a gas or electric motor. youtu.be/8Y_Ioc_8Fys

Have you ever wondered what enables successful knowledge exchange at the interface of environmental science, policy & management? To address this question, we undertook a global review of the published literature, which is now available online & open access: onlinelibrary.wiley.com/doi/10.1002/...

Ever wonder what your tagged fish are up to between receiver fixes? See them in real-time! Who are they hangin' with? What are they snackin' on? 3D activity? See the big picture using integrated #sonar and acoustic biotelemetry methods. For more information www.milnetechnologies.ca/sonartags.htm.

This is our first bsky message! Good to be on this site

Imaging multibeam #sonar systems, such as #ARIS or #Flexview, are ideal for detecting and identifying species-at-risk in riverine and shallow water systems. Shown is a #Sturgeon detection from a fish passage survey of the Fraser R. Automated target detection using Echoview. #Hydroacoustics

Wanna detect tagged fish, see untagged fish and map bottom habitat at the same time? You can! Ideal tool for identifying & mapping spawning areas or to assess #Sturgeon in large rivers. Learn more about our multibeam mapping & fish tag detection sonar system. www.milnetechnologies.ca/sonartags.htm

Want your fish to show you where they like to hang out? What nearshore habitats they prefer? Where they prefer to aggregate when spawning or feeding? Well, now you can, using our new multibeam mapping and fish tag detection sonar! See tagged and untagged fish together! Ideal for #Sturgeon too.

Welcome aboard! The new lead editor for the Journal of Great Lakes Research, Margaret Docker, is officially on the clock. The final months of 2024 will be a transition phase working with outgoing editors and she will assume the full role in January 2025. #GreatLakesSci

Nice to see you all again! Happy to replace my tweets with skeets?..bleets? idk...🤷‍♂️ I’m Scott Milne and I bleet about #hydroacoustics, sonar imaging, acoustic biotelemetry, and fish habitat mapping. I hope you enjoy this #ARIS multibeam echogram of a baitfish school being attacked by Rainbow Trout.

#IAGLR25 is the perfect opportunity to get your science in front of #GreatLakesSci colleagues. The abstract submission portal is now open and runs through Monday, December 16. Follow the link for further information: bit.ly/3X1fPKC
