It’s a big ocean, but small fish experience it at fine scales. Our Pacific Salmon Foundation funded study in #ProgressinOceanography reveals details of juvenile #chinooksalmon habitat use and highlights the importance of #pacificherring.

First abundance estimates for two African dolphin species were derived using passive acoustic monitoring and visual observations from ship surveys off Namibia, now published in Frontiers in Marine Science and the African Journal of Marine Science. Morgan Martin, who recently joined our lab, was involved with both of these projects. You can see her and the other co-authors discussing their research here https://www.youtube.com/watch?v=rsStzGpPPWg&t=321s The Fulbright Program Sea Search National Geographic

A Bayesian analysis of the factors determining microplastics ingestion in fishes is now published in the Journal of Hazardous Materials! Led by Garth Covernton, this innovative review and analysis of #microplastics ingestion in marine and freshwater fishes determined that biomagnification across trophic levels may not be a major factor when considering plastic's movement through ecosystems. This work was a collaborative effort involving Juanes lab graduate students Hailey Da...vies and Kieran Cox, professors John Dower, Rana El-Sabaawi, and Francis Juanes, and Sarah Dudas of Fisheries and Oceans Canada.

Seals as underwater soundscape influencer? This study evaluated the seasonal and monthly dynamic in bearded seal vocalizations, and demonstrated for the first time their impact on underwater sound levels throughout the mating season in the Canadian Beaufort Sea. Led by Annika Heimrich under supervision from Dr. William Halliday, and support from Dr. Héloïse Frouin-Mouy, Dr. Mathew Pine, Dr. Francis Juanes, and Dr. Stephen Insley. This project was made possible with the help ...of the people of Sachs Harbour, specifically the Sachs Harbour Hunters and Trappers Committee, W. Gully, B. Hoagak, T. Lennie, J. Kudak, and J. Kuptana. Funding was provided by The W. Garfield Weston Foundation, the MEOPAR (Marine Environmental Observation, Prediction, and Response) Network of Centres of Excellence, the Liber Ero Foundation, and the World Wildlife Fund. https://onlinelibrary.wiley.com/doi/abs/10.1111/mms.12732

The soundscape of the Anthropocene ocean in Science. Here, an incredible international collaboration lead by Dr. Carlos Duarte, which included Dr. Francis Juanes, explores how ocean soundscapes have lost animal sounds, changed with the climate, and been bombarded by human noise, and more importantly provides important insight into how we can better manage marine soundscapes.

Interested in reef acoustic? Comparisons between sound pressure levels and acoustic complexity index on coral reefs reveal the complexity index's dependence on its settings to describe biogenic sounds. Now published in Ecological Indicators, led by Sean Dimoff, supported by Dr. William Halliday, Dr.Matt Pine, Kristina Tietjen, Dr. Francis Juanes and Dr. Julia Baum, and funded by Mitacs and Nserc Canada.

Have you ever wondered how many fish species produce sound, how fish sounds are documented, or what fish sound like? Then MERIDIAN's recent webinar is for you! Audrey Looby and Amalis Riera outline our ongoing collaboration to create an online catalog of global soniferous fish diversity. The webinar is now archived on YouTube. https://www.youtube.com/watch?v=qCeIvtGgFbA&feature=youtu.be UF IFAS Nature Coast Biological Station University of Victoria Natural Sciences and Engineering Research Council of Canada Dalhousie University

PhD student Rhonda Reidy, co-supervised by Francis Juanes and Laura Cowen, is involved in a collaborative project with ASL Environmental Sciences Inc. and Stephane Gauthier of Fisheries and Oceans Canada. The project investigates collecting time-series data on prey composition and spatiotemporal dynamics of humpback whales off Vancouver Island, using multi-sensor suction cup tags on humpback whales with concurrent measures of prey from a scientific echosounder. In September 2020, data collection occurred at the western entrance to Juan de Fuca Strait where humpback whales aggregate for feeding, but overlap directly with shipping lanes. https://aslenv.com//ASL-Press-release-Reidy-NSERC-grant-No

As a part of the Salish Sea Marine Survival Project (https://marinesurvivalproject.com/), Juanes lab graduate Jacob Weil determined fine-scale differences in the caloric content of prey for juvenile Chinook Salmon and developed best practice for classifying prey in salmon diet studies. https://www.int-res.com/abstracts/meps/v655/p185-198 @UUniversity of Victoria CRSNG / NSERC

'Towards an Optimal Design for Ecosystem-Level Ocean Observatories' is now published and #openaccess. This publication details how the incorporation of multiple integrated observation technologies can enable the unprecedented quantification of macrofaunal composition, abundance, and density surrounding the module, as well as the ability to track the movements of individual fishes and macroinvertebrates.

Arctic cod accounts to up to 75% energy transfer from the zooplankton to marine mammals and sea birds in the Arctic, but their distributions are difficult to study thanks to their over-winter spawning. Passive acoustic monitoring (PAM) could be a useful tool now that we have some idea of what Arctic gadids sound like, and their detectability using hydrophones. Our new paper in Polar Biology describes the sounds of Arctic gadids recorded in the field to help the development of... PAM systems for fish.
