New FCRRs: Historical Ecology in Burrard Inlet and Reconstructing the pre-contact shoreline of Burrard Inlet
These two new Fisheries Centre Research Reports will help us understand the overpowering changes that colonial settlement and development has had on the marine ecosystems surrounding the Lower Mainland area of British Columbia.
Data confirm link between respiratory stress and fish reproduction
A consistent metabolic ratio found across 133 Chinese marine and freshwater fish species provides new evidence in support of the idea that fish become sexually active – and spawn for the first time – in response to growth-induced respiratory stress.
PROFILE: Saving British Columbian streams, rivers and lakes for fish
The Applied Freshwater Ecology Research Unit’s (AFERU) job is to find ways to conserve freshwater species, test effectiveness of current conservation strategies, and understand how freshwater fish are responding to changes in their habitats.
What really makes fish become sexually active
“What I think really makes fish spawn for the first time is the increasing oxygen stress that growing fish experience,” Daniel Pauly said
In Memoriam – Josef (Joe) Bauer
A much revered fisherman, teacher, student, researcher, environmentalist, and Adjunct Professor with the Institute for the Oceans and Fisheries and its previous incarnations.
China and the E.U. aren’t the only ones to blame for harmful fisheries subsidies
“Don’t think that just because you’re not providing six billion dollars that you’re not impacting, or potentially impacting the sustainability of the fish stock.”
Ecosystem modelling indicates that adding fertilizer to water reservoirs pays off
In the simulated Arrow Lakes Reservoir, fish fared better when nutrients were added to the water, regardless of whether the water flow was high or low.
IOF researchers find simple solution to Kuwait’s blood snapper woes
The change could help repopulate Malabar blood snapper, whose numbers dropped by 95% between 1995 and 2009
Tilapias are not precocious, they are just resilient
Tilapias living in crowded aquaculture ponds or small freshwater reservoirs adapt so well to these stressful environments that they stop growing and reproduce at a smaller size than their stress-free counterparts.
