Diel Vertical Movements and Feeding Habits of Underyearling Sockeye Salmon (O...
Sockeye underyearlings at Babine Lake. B.C. were observed to undergo diel vertical movement from July through to October 1967. This movement was more pronounced in August when the lake was most distinctly thermally stratified. The presence of a sharp... -
Orientation Differences Between Populations of Juvenile Sockeye Salmon
British Columbia's Babine Lake system has three populations of sockeye salmon smolts which travel different routes to the outlet on their seaward migration. The objective of this study was to determine if the directional preferences of these populations are... -
Assessment of Wild Steelhead Abundance Trends in British Columbia (1967/68-19...
Intra-regional similarities and inter-regional differences in wild steelhead (Oncorhynchus mykiss) abundance patterns over time throughout British Columbia were identified using Catch-per-Angler-Day (CpAD) as an index of abundance of wild in-river adult... -
The Salinity Intrusion of the Skeena River Observations of Salinities, Temper...
Observations of salinities, temperatures and currents are presented in the form of vertical profiles at stations in the lower reaches of the Skeena River and in the approaches to the estuary. The data were obtained at freshet conditions in the summer of... -
Skeena Salmon Test Fishery 1987
Information relating to the Skeena River gillnet test fishery program for 1987 and a summary for the years 1955 to 1976 is presented in this report. Daily catch of all salmon species (Oncorhynchus~) and steelhead trout (Salmo gairdneri) are detailed by set... -
Provisional Estimates of Numbers and Biomass for Natural-Origin and Hatchery-...
This report provides provisional abundance estimates for pink, chum, and sockeye salmon in major regions of the North Pacific from 1952 through 2015 in terms of: numbers of natural- origin and hatchery-origin salmon returns (i.e., catch plus escapement),... -
Biophysical Stream Survey of Fourteen Sockeye Streams Tributary to Babine-Nil...
This stream inventory aims to employ a biophysical method of aquatic systems inventory to the fourteen sockeyes streams, experiment with methodology based on low-level Arial inventory, and provide Fisheries Service personnel with a better data base. -
An Inventory of Thautil River and Tributaries
On two separate occasions, June 21 and July 16-18, 1978, the Thautil River Watershed was surveyed to assess its fish presence and diversity. Personnel from the Inventory Section, Fish and Wildlife Branch surveyed the Thautil River with particular emphasis... -
A Review of the Babine Lake Development Project 1961-1976
This report describes the results of the Babine Development Project evaluation program relative to the individual components within project, containing components which describe the individual projects from the predevelopment stage to the present. -
A Preliminary Evaluation of the Environmental Impact of Mining, Community Dev...
An ecological study to assess the impact of environmental changes on the Babine sockeye production is currently being conducted under the auspices of the Babine Watershed Change Program. Specifically the Environmental Quality Unit of the Northern Operations... -
Reconstruction of the Total Return of Sockeye Salmon (Oncorhynchus nerka) to ...
An assessment of the total return of sockeye salmon to the Skeena River is presented for brood years from 1965 to 1982. Annual reconstructions required catch and spawning escapement data. Age structure information was used to apportion the catch and... -
Upper Skeena Chinook Stocks: Evaluation of the Bear-Sustut, Morice, and Lower...
The chinook salmon (Oncorhynchus tshawytscha) escapements to the Skeena River have declined from 1950 to 1973 (Figure 1). In 1973, restrictions on sport and commercial fisheries were implemented to aid in recovery of Skeena River chinook stocks.... -
An Attempt to Determine Abundance and Distribution of Migrating Skeena River ...
Echo surveying is one of the newer techniques for estimating the abundance and distributional patterns of fish stocks and its potential seems promising as it is a convenient, economical and effective way of collecting information on underwater objects.... -
Hydrographical Studies Associated with Salmon in the Nanika and Morice Rivers
Hydrographical studies have been undertaken since 1971 by the Fisheries and Marine Service in the prime spawning areas of the Nanika and Morice Rivers. The purpose of the studies was to document the physical and hydraulic conditions under which spawning and... -
Sockeye Egg-to-Fry Mortality in the Fulton River Spawning Channels
Possible causes of low egg-to-fry survival of sockeye salmon (Oncorhynchus nerka) in the Babine Lake artificial spawning channels were studied from November, 1971 to March, 1972. Concurrent studies were conducted on the Fulton River and Pinkut Creek... -
Zooplankton Abundance in Lakes Sampled by the 1978 British Columbia Lake Enri...
Zooplankton samples were collected from 14 lakes on the Central and North Coast and the Skeena and Nass systems. The purpose of the sampling was to collect data on zooplankton abundance and species composition from a fertilized lake (Long) and lakes being... -
Chinook Salmon in the North Coastal Division
Concern over the status of chinook salmon on the Pacific Coast, and particularly in the north (Fig. 1), has become more prevalent in recent years due to an apparent decline in stock size. This concern emphasizes the need for better conservation, improved... -
