Enhancement of British-Columbia-to-Alaska Transboundary Rivers is a vast potential prize to all concerned. However, despite funding commitments in the Pacific Salmon Treaty, that program is at great risk of always being more potential than real. The cooperation needed to make this program work has been and continues to be grievously...
Canada’s Department of Fisheries and Oceans seeks to manage British Columbia’s prawn fishery by limiting the season length, vessel entry, and the number of prawn traps per vessel. However, fishers can still adjust their effort by increasing the number of trap lifts during the season.
This study examines the effect...
Bleach has been used for decades as an irritant in the British Columbia (BC) commercial octopus dive-fishery. Recently the FAO (United Nations Food and Agriculture Organization) declared that using noxious substances in any fishery is considered unlawful, under international law. Canada’s Department of Fisheries and Oceans (DFO) has asked BC...
In recent decades, distant-water fishing vessels (DWFVs) have drawn increasing criticism for exacerbating misery in developing nations. As part of a resolution to this issue, a coalition of academics, fishers, processors and others developing nations are field-testing new technologies to extend the fishing power and reach of local small-to-medium-boat artisanal...
Teaching GIS involves teaching ethical and moral thinking as a distinct engagement with
the use, applications, and responsibilities of GIS professionals. Over the past 20 years
scholars (particularly those affiliated with the discipline of Geography) have contributed
critiques of the instrumental nature of GIS as well as reflective case studies...
After hatchery-reared salmonids are released into the wild, their survival and performance are
frequently lower than those of wild conspecifics. Additionally, negative effects of hatchery fish on wild fish are cited as factors affecting the recovery of salmonid populations. Alternative hatchery rearing environments and release practices have been proposed to...
Thiamine (vitamin B₁) deficiency is a global concern affecting wildlife, livestock, and humans. In Great Lakes salmonines, thiamine deficiency causes embryo mortality and is an impediment to restoration of native lake trout (Salvelinus namaycush) stocks. Thiamine deficiency in fish may result from a diet of prey with high levels of...
New seafloor mapping and sampling demonstrates that the eruption of the high-Ca boninites is clearly associated with rifting of the northern Tonga ridge and the northern Lau Basin at the northern termination of the Tonga Trench. There is very strong evidence for OIB plume related mantle sources involved in the...
