Analysis of Ultrasonic Tracking Records of Adult Sockeye Salmon Migration in ...
Migratory pathways of adult sockeye salmon (Oncorhynchus nerka) on their way to the spawning grounds in Babine Lake were monitored by ultrasonic tracking techniques in 1969 and 1970. This report presents procedures and computer programs used for processing... -
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... -
An Environmental Assessment of the Watershed Adjacent to Hallmark Resources, ...
The Environmental Protection Service is engaged in monitoring programs of the various industrial concerns that constitute potential hazards to the receiving water quality. The Water and Land Quality Group is specifically concerned with measuring deleterious... -
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... -
A Polymorphic Population of Oncorhynchus Nerka at Babine Lake, B.C. Involving...
This thesis studies the reproductive behavior, life cycles, and physical differences between Kokanee and Sockeye salmon in the Babine Lake streams, along with the possible causes for these differences. -
Acute and Sublethal Copper Sensitivity, Growth and Saltwater Survival in Youn...
A series of experiments was conducted during the spring, summer and fall of 1977 to determine the potential copper toxicity hazard to Babine Lake sockeye salmon (Oncorhynchus nerka) fry, lake fingerlings and smolts. Acute 96 h LC50's were determined for the... -
Timing of Babine Lake Sockeye Salmon Stocks in the North-coast Commercial Fis...
Approximate timing of Babine Lake stocks in the fishing area has been shown by tagging there and in the Skeena River estuary, and recovering tagged fish on Babine Lake spawning grounds (see Takagi and Smith MS 1973 for a summary). However, mixing with other... -
The Marking of Sockeye Salmon Fry (Oncorhynchus nerka) at Fulton River and Pi...
The Fisheries Service of the Department of the Environment is currently attempting to increase sockeye production by increasing the number of fry entering the lake, thus making fuller use of its potential as a nursery area (Dep. Fish 1965; McDonald 1969).... -
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... -
The Trapping and Marking of Sockeye Salmon Fry at Fulton River, Babine Lake B.C.
A comparative study of the distribution, growth, and survival of sockeye salmon fry resulting from the same parental stocks, but reared in natural and artificial conditions began in 1966 (McDonald 1969). Fry produced from natural spawning in the Fulton... -
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... -
Age and Size of Rainbow Trout at the Outlet of Babine Lake and in Babine River
Rainbow trout are the most important sport fish in terms of angling effort in the Babine Lake system. Griffiths (1968) has reported on the age and growth of rainbow trout in the main part of Babine Lake but little or no information exists for Babine River.... -
Chemical Studies of the Recent Sediments of Babine Lake British Columbia
The multi-disciplinary Babine Watershed Change Program (1973) was initiated in 1971-1972 by the Department of the Environment to assess effects of environmental change on Babine salmon and trout production. The program includes paleolimnological studies to... -
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... -
Fulton River Upwelling Gravel Incubator for Sockeye Salmon
A styrofoam insulated upwelling gravel incubator employing a gravel substrate and partially filtered river water was tested under extreme cold weather conditions and evaluated as a technique for propagating sockeye (Oncorhynchus nerka) salmon at Fulton...
