Projected shifts in climate forcing variables such as temperature and precipitation are of great relevance to arctic freshwater ecosystems and biota. These will result in many direct and indirect effects upon the ecosystems and fish present therein. Shifts projected for fish populations will range from positive to negative in overall effect, differ among(More)
Arctic freshwater and diadromous fish species will respond to the various effects of climate change in many ways. For wide-ranging species, many of which are key components of northern aquatic ecosystems and fisheries, there is a large range of possible responses due to inter- and intra-specific variation, differences in the effects of climate drivers(More)
Three independent modeling methods—a nutrient-phytoplankton–zooplankton (NPZ) model (NEMURO), a food web model (Ecopath/Ecosim), and a bioenergetics model for pink salmon (Oncorhynchus gorbuscha)—were linked to examine the relationship between seasonal zooplankton dynamics and annual food web productive potential for Pacific salmon feeding and growing in(More)
Nest site fidelity and serial polyandry were examined in lingcod, Ophiodon elongatus, a teleost fish in which the nest-guarding male parent invests more heavily in parental care than the elusive female parent. Lingcod parental and progeny genotypes were established for fish spawning on a 200 m(2) section of Snake Island reef, British Columbia in two(More)
A complete photographic system for performing real-time holographic interferometry is described. The holograms are recorded on an experimental film that permits rapid, dry, in-place processing in a specially designed chamber. The expose-process-view cycle is fully automated so that real-time interferograms can be produced with ease. The features of the(More)
The Fishery Total fishery landings of all marine fish off the west coast of Canada (Fig. 3) increased during the 1980s, reaching a maximum of 417,777 t in 1994, and declined through to the present, approaching landings common in the early 1980s (Fig. 4). The commercial fishery off Canada's west coast has been strongly influenced by the size and value of the(More)
