May 2016

·         Brendan has another paper accepted for publication! It will be in Reviews in Fish Biology and Fisheries and is called ”In search of a cultured fish phenotype: a systematic review, meta-analysis and vote counting analysis”

·         Heather, Brittany and Craig have submitted a variety of talk titles for the upcoming Canadian Society for Ecology and Evolution meeting, and the International Marine Conservation Congress meeting, but of which are happening in St. John’s this July.


April 2016

·         Congrats to Tanner on winning a MUN Science Undergraduate Research Award for summer 2016

·         Congrats to Brittany, Heather and Tanner on winning first place in the poster competition at the 9th annual Biology Graduate Student Symposium

·         Research in the lab will be ramping up in intensity starting in summer 2016 thanks to 4 new grants

o   NSERC Discovery Grant (5 years)

§  Gamete ecology in variable environments

o   Atlantic Salmon Conservation Foundation Grant (3 years)

§  Incubation sensitivity to winter temperatures in four DUs of Atlantic salmon in Canada

o   DFO National Contaminants Advisory Group Grant (1 year)

§   Impacts of crude oil and dispersants on capelin reproductive performance

o   Atlantic Salmon Conservation Foundation Grant (3 years)

§  Salmon gametes as a source for research, restocking and public education


March 2016

·         Congratulations to Heather who has won a Community Service Award from the School of Graduate Studies


February 2016

·         Craig appeared as a guest on CBC Radio’s “On the Go” program to discuss the relationships between trout and salmon


January 2016

·         Craig was the chief organizer for the 69th Canadian Conference for Fisheries Research, which ran Jan 7-9. Our lab was also an author on 6 presentations.

·         Paper by former MSc student Corey Clarke has been accepted by the journal Animal Conservation. It is titled “Lifelong and carry-over effects of early captive exposure in Atlantic salmon”, and was done in Fundy National Park.

·         Craig was interviewed live on the NTV Evening Newshour about what we have learned since the collapse of the northern cod stocks 25 years ago


December 2015

·         Our work on sperm ecology has been heavily featured in a review published this month by Reinhardt, Dobler and Abbott (Annual Review of Ecology, Evolution and Systematics 46:435-459). In many ways it is similar conceptually to the NSERC Discovery Grant proposal (Gamete ecology in variable environments) that Craig currently has in review.


November 2015

·         Craig gave an invited seminar at the University of Manitoba on Nov 6 called “Gamete plasticity under environmental perturbation”

·         Craig was interviewed twice by the CBC to discuss the effects of breeding between farmed and wild salmon, and factors influencing recruitment in capelin


October 2015

·         Welcome to Tanner Stein, who joined the group as a new MUCEP student

·         Craig gave an invited public lecture for Nature NL on Oct 15 titled “Weird sex: the unusual morphology, behaviour and gametes of capelin”


September 2015

·         Paper by Wringe, Fleming and Purchase entitled “The spawning success of cultured and wild male Atlantic cod does not differ during paired contests” has been published in the Marine Ecology Progress Series.

·         Paper by Brendan entitled “Rapid morphological divergence of cultured Atlantic cod of the northwest Atlantic from their source population” has been published in Aquaculture Environment Interactions

·         Craig gave an invited talk entitled “The future of salmon in our rivers” to the AGM of the Northeast Avalon Atlantic Coastal Action Program.
