An Upstream Battle: declines in 10 Pacific salmon stocks and solutions for their survival
Habitat, Marine Survival, Productivity, Recovery Plan, Review, status assessmentExecutive Summary This report profiles the current status and trends of 10 examples of salmon stocks in British Columbia that are considered to be in a severe state of decline. (There are many others.) These stocks were selected because they…
A widespread decrease in productivity of sockeye salmon (Oncorhynchus nerka) populations in western North America
Biological Production, ProductivityAbstract We used data on 64 stocks of sockeye salmon (Oncorhynchus nerka) from British Columbia (B.C.), Washington, and Alaska to determine whether recent decreases in abundance and productivity observed for Fraser River, B.C., sockeye have…
Stock status and lake based production relationships for wild Skeena River sockeye salmon
Productivity, Stock StatusAbstract This paper outlines stock status for wild Skeena River sockeye salmon based on updated assessments of freshwater production in nursery lakes, available catch and escapement data, and modelled exploitation rates. The aggregate stock…
Factors Limiting Juvenile Sockeye Production and Enhancement Potential for Selected BC Nursery Lakes
Enhancement, Lake Fertilization, Nursary Lakes, ProductivityAbstract In this report we present summaries of our current knowledge of freshwater factors limiting sockeye production from 60 B.C. lakes. Data were collected between 1977-2000. Quantity of data available for each lake varied, ranging from…
Stock status of northern boundary coho: Canadian Report
Productivity, status assessmentAbstract This document presents an assessment of the status of coho salmon (Oncorhynchus kisutch) in the Canadian northern boundary areas with emphasis on the Skeena River. The content of this assessment has largely been drawn from published…
Trophic status and rearing capacity of smaller sockeye nursery lakes in the Skeena River system
environmental surveys, nursery ponds, Productivity, Rearing Capacity, trophic levelsAbstract The Skeena River system has one large sockeye (Oncorhynchus nerka) nursery lake (Babine Lake) and approximately 26 smaller lakes. In this study, we investigated 10 of the larger non-Babine nursery lakes in the system. We examined lake…
