Singing fish in a sea of noise, an article written by Juanes Lab MSc student Kenzie Woods was recently published in Fisheries, and plainfin midshipman fish took the spotlight on the front cover.

Read about how cool these fish are, including their different vocalizations, parental care behaviour, and how they’re being affected by human noise in this “Cool Fish” column photo article: https://doi.org/10.1002/fsh.10907

Forage fish, juvenile salmon, kelp...what more could you ask for? A great collaboration with Coastal Watershed Institute that began as a UVIC Biology directed studies in the Juanes Lab is now published. "Dynamics of juvenile salmon and forage fishes in nearshore kelp forests" https://onlinelibrary.wiley.com/doi/10.1002/aqc.3957

A new research article from our PhD student Micah has been uploaded to CJFAS in the “just-in” section (https://doi.org/10.1139/cjfas-2021-0088). In this article he compares automated 3D otolith morphometrics to manual 2D and automated 2D methods. He found that overall, the automated 3D method was not only faster, but it captured relevant z-axis information that is not possible to reduce in a photograph. This is a nice paper for fisheries managers and researchers to read when considering the way they will measure otoliths.

One of our lab programs, the Southern B.C. Adult Salmon Diet Program, was recently covered by the National Observer. This research is an important ecosystem monitoring project centered around chinook and coho salmon here in Southern BC. This program has become a success due to the information sharing and mutual respect between our university personnel on the program and our citizen scientist anglers. To learn more, feel free to join the page. We also have an essay in Fisheries (https://doi.org/10.1002/fsh.10478).

Squeezing out fish stomachs and poking through intestines may be distasteful, but it’s part of a collaborative effort by researchers and recreational fishermen to save endangered salmon and divine climate-fuelled shifts to the marine food web.

Are you fishing for rockfish?! We need your help!

If you capture a tagged fish, we’d love to hear about it - please follow these steps to help with our data collection:
- Take a photo of the fish & tag number (note: the tag may be a different colour than the one shown in the photo)
- Record date, location & depth of capture
- Return to water using a descending device (a SeaQualizer is shown on the poster, but please use any method of descending you are comfortable with) - Email or call: Hailey Davies ([email protected]) or Dana Haggarty ([email protected], 250-327-4860)
- Earn a rockfish hat reward!
Bonus - log your catch using the MyCatch or FishingBC app

Documenting tagged rockfish will help us, researchers based out of the University of Victoria and Fisheries and Oceans Canada, as we study the effectiveness of descending devices at increasing long-term survival of BC inshore rockfishes. If you’d like more info about the work we’re doing, we are happy to get in touch!
