NEWS FROM THE LAB

November 2018

·         Craig and Anna, along with Mike Rennie (Lakehead U) and Jay Treberg (U Manitoba) will be presenting work on lake trout reproduction at the upcoming Canadian Conference for Fisheries Research.  “Old funks don’t always have junk spunk: a clear lack of reproductive senescence in  sperm quality within the long-lived indeterminate growing lake trout”

 

October 2018

·         We had a team of 6 at the ERMA facilities on the Grandfalls fishway, where we sampled 70 salmon for Madison’s project on among-individual variation in sperm quality.

·         Jose submitted a second paper on the effects of potential oil spills on capelin reproduction

·         We were thrilled to be hosting Geoff Parker (retired University of Liverpool) who received an Honorary Doctor of Science from MUN on October 18.

·         Craig was interviewed October 10 about “Cressie” for an upcoming episode of the TV show “Rare Earth Uncovered” on APTN.

·         Welcome to Taylor Hughes and Coady Fitzpatrick who join the lab as MUCEP students, and Terry Sullivan who is back with us for the 3rd fall of salmon spawning.

 

September 2018

·         Anna has submitted paper on predictive models for salmon incubation as a function of temperature. Work was funded by Atlantic Salmon Conservation Foundation.

 

August 2018

·         Craig spent 7 days in a remote site of Prince William Sound Alaska, working with Peter Westley (UAF) on pink salmon reproduction

 

July 2018

·         We put a big effort into work on post-mating cryptic female choice in capelin with Trevor Pitcher (U Windsor) and Jon Evans (U Western Australia)

·         Also collected spawning capelin for collaborative work with a University of Alaska Fairbanks student.

 

May 2018

·         Craig and Anna presented research on developmental timing of Atlantic salmon embryos during the Canadian Society of Zoologist meeting

·         Heather’s first paper from her PhD has been accepted in Evolutionary Ecology Research.

·         Collaborative work with a conservation angling group (SAEN) on the technique use of instream salmon incubators has been published in the North American Journal of Fisheries Management. This was funded by the Atlantic Salmon Conservation Foundation, and is titled “Performance of instream Jordan-Scotty salmon egg incubators under different installation and siltation conditions”. https://onlinelibrary.wiley.com/doi/abs/10.1002/nafm.10052

·         Paper on capelin embryo development to varying salinities has been published by CJFAS http://www.nrcresearchpress.com/doi/10.1139/cjfas-2017-0058#.WvRcN38h2Uk

 

April 2018

·         Received news that NSERC has awarded a collaborate equipment grant with Yolanda Wiersma and Carissa Brown for a new field truck.

·         Welcome to Tyler Lantiegne, who joins the lab as a new MSc student in May. Tyler is from, and has been trained to date in Alaska. He will be working on cryptic female choice over sperm competition in hybridizing salmonids.

 

March 2018

·         Welcome to Madison Philipp, who joins the lab as a new MSc student in May. Madison is from Illinois and did her undergraduate degree at Dalhousie in Nova Scotia. She will be working on among-male variation in sperm ecology.

·         Steven, Heather and Craig attended an interesting WWF workshop on fish habitat restoration on March 1.

·         Craig was an invited expert at the DFO salmon assessment meeting on Feb 28, and for the capelin assessment meeting on March 7.

·         A new project has been approved that will spread our research on gamete ecology to a new system in Alaska. Craig and former MUN student Peter Westley will instigate this in August 2018.

 

February 2018

·         Paper on very unique capelin sperm has been published in Ecology & Evolution http://onlinelibrary.wiley.com/doi/10.1002/ece3.3783/full

 

January 2018

·         Craig gave a seminar Jan 31, at the Marine Institute School of Fisheries, called “Quirky sex on the beach: Newly discovered perils of capelin reproduction”

·         Work with colleagues in Manitoba on chemical signatures of capelin otoliths has been published
