Exploring the Biological Basis of Age-Specific Return Variability of Chinook Salmon (Oncorhynchus tshawytscha) From the Robertson Creek Hatchery, British Columbia Using Biological or Physical Oceanographic Explanatory Variables
Autor: R. W. Tanasichuk, S. Emmonds
Publikováno v: The Open Fish Science Journal. 9:15-25
We used information about hatchery rearing and release practices for 173 releases of age 0+ smolts between 1982 and 2012, as well as time series of early marine prey biomass and predator abundance/biomass, to investigate the biological basis of age-s

An investigation of the biological basis of return variability for sockeye salmon (Oncorhynchus nerka) from Great Central and Sproat lakes, Vancouver Island
Autor: R. W. Tanasichuk, R. Routledge
Publikováno v: Fisheries Oceanography. 20:462-478
We tested whether variations in stock characteristics (spawner and smolt abundance) and biotic conditions (prey variability, predation, competition) during the early marine period explained variations in the return of sockeye salmon (Oncorhynchus ner

Implications of interannual variability in euphausiid population biology for fish production along the south-west coast of Vancouver Island: a synthesis
Autor: R. W. Tanasichuk
Publikováno v: Fisheries Oceanography. 11:18-30
This is a synthesis of published and unpublished research on euphausiid and fish populations using the south-west coast of Vancouver Island. Overall, the studies covered 1985–98, when there were two ENSO events and considerable variation in upwelli

A Northern Extension of the Range of the Euphausiid Nyctiphanes Simplex into Canadian Waters
Autor: R. W. Tanasichuk, C. Cooper
Publikováno v: Journal of Crustacean Biology. 22:206-209
We collected Nyctiphanes simplex in Barkley Sound, Canada (48°54′N, 125°6′W) between May and September 1998. This was during the most intensive ENSO (El Nino Southern Oscillation) event recorded and when southward current velocities were anomal

Age-specific natural mortality rates of adult Pacific herring (Clupea pallasi) from southern British Columbia
Autor: R W Tanasichuk
Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 57:2258-2266
I used data for over 665 000 Pacific herring (Clupea pallasi) seined or gillnetted in southern British Columbia between 1951 and 1998 to estimate age- and year-specific adult natural mortality rates. Apparent sampling bias precluded using data collec

Influence of biomass and ocean climate on the growth of Pacific herring (Clupea pallasi) from the southwest coast of Vancouver Island
Autor: R W Tanasichuk
Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 54:2782-2788
I examined the growth of Pacific herring (Clupea pallasi) from the southwest coast of Vancouver Island using data for over 83 000 fish seined between 1975 and 1996. Size-at-age (length, total mass) of recruits (age 3) was negatively related to parent

Comparison of Some Life History Characteristics of Pacific Herring (Clupea pallasi) from the Canadian Pacific Ocean and Beaufort Sea
Autor: A. H. Kristofferson, R. W. Tanasichuk, D. V. Gillman
Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 50:964-971
We compared several growth and reproductive characteristics of Pacific herring (Clupea pallasi) from the Canadian Pacific Ocean and Beaufort Sea using data for 2310 fish gillnetted in the northern Strait of Georgia or near Tuktoyaktuk, N.W.T., over t

Variations in Diet, Daily Ration, and Feeding Periodicity of Pacific Hake (Merluccius productus) and Spiny Dogfish (Squalus acanthias) off the Lower West Coast of Vancouver Island
Autor: W. Shaw, G. A. McFarlane, R. W. Tanasichuk, D. M. Ware
Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 48:2118-2128
We examined aspects of summer feeding in Pacific hake (Merluccius productus) and spiny dogfish (Squalus acanthias). Euphausiids (Thysanoessa spinifera, Euphausia pacifica) and Pacific herring (Ciupea harengus pallasi) accounted for almost all of the
