A review of oocyte development in fishes with special reference to Pacific hake (Merluccius productus) by R. P Foucher( Book )

6 editions published between 1977 and 1978 in English and held by 23 WorldCat member libraries worldwide

A guide to the ovarian histology of Pacific cod by D. G Bowden( Book )

10 editions published between 1989 and 1990 in English and held by 19 WorldCat member libraries worldwide

The development of the ovary of Pacific cod was examined macroscopically and by microscopic cross section. Oocyte growth and development were recorded by photomicrography for correlation with macroscopic maturity stages of the ovary. Characteristics were described for each maturity stage. A glossary of commonly encountered terms was compiled for use in future investigations of reproductive biology of fishes

4 editions published in 1986 in English and held by 8 WorldCat member libraries worldwide

Stock assessments and yield options are developed for the Pacific coast ofCanada for the following species: lingcod, Pacific cod, Dover sole, rocksole, English sole, sablefish, Pacific hake, spiny dogfish, walleye pollock, pacific ocean perch, yellowmouth rockfish, rougheye rockfish, silvergreyrockfish, yellowtail rockfish, and canary rockfish.

Canada-U.S. landing statistics and age composition for Pacific cod (Gadus macrocephalus) from trawling grounds off the southwest coast of Vancouver Island, 1956-81 by S. J Westrheim( Book )

Estimation of the fecundity of Pacific cod (Gadus macrocephalus) by R. P Foucher( Book )

4 editions published in 1990 in English and held by 6 WorldCat member libraries worldwide

The determination of fecundity in both the Hecate Strait and west coast of Vancouver Island (LaPerouse area) was carried out as part of an investigation of the reproductive biology of Pacific cod. This project covered 5 spawning seasons (1986-90) and included two widely-separated regions within BC waters for 1988. Comparisons were made by year and geographic region and the relationship to temperature was also investigated
The spawning season of Pacific cod on the west coast of Canada by R. P Foucher( Book )

4 editions published in 1990 in English and held by 6 WorldCat member libraries worldwide

The spawning season of Pacific cod in British Columbia is primarily January-March, based on 46,106 trawl-caught specimens sampled during 1976-85 at processing plants. Gonad development for both sexes was similar among four areas, but occurred later in the northermost area (north Hecate Strait). Spawning was apparently determinate and essentially complete by May in north Hecate Strait, and by April elsewhere. Considerable variability was found among hauls and among years within months
Length composition of Pacific cod (Gadus macrocephalus) from commercial landings by Canadian trawlers 1974-85 by R. P Foucher( Book )

Landing statistics and age compositions for Pacific cod (Gadus macrocephalus) from Queen Charlotte Sound, 1956-81 by R. P Foucher( Book )

2 editions published in 1983 in English and held by 5 WorldCat member libraries worldwide

Length-at-age by sex for Pacific cod in British Columbia by R. P Foucher( Book )

5 editions published in 1990 in English and held by 5 WorldCat member libraries worldwide

Because the stocks of Pacific cod in Canadian waters appear to have only 7 or 8 age classes that can be detected as distinct modes, routine estimations of age composition have been carried out using length-frequency data only, without regard to sex. This paper examines the evidence for any significant difference in mean length at age by sex and evaluates the impact this might have on the age-determination method. Methods used include age determination using skeletal structures; tagging experiments; prominent modes; age determination by length-frequency analysis; and sex ratio
Standardized landings statistics for Pacific cod (Gadus macrocephalus), and important shelf co-habitants from off southwest Vancouver Island, and from Queen Charlotte Sound and Hecate Strait, 1956-85 by R. P Foucher( Book )

4 editions published in 1987 in English and held by 5 WorldCat member libraries worldwide

Update of 1985 report on landings, effort, and landings per unit effortcalculated for Pacific cod in each area plus lingcod and petrale sole offsouthwest Vancouver Island, lingcod and rock sole in Queen Charlotte Sound, and Dover sole, English sole and rock sole in Hecate Strait. The data wererefined by using the Option-2 method and standardized to correct for changingvessel efficiency
Landings and age compositions for pacific cod (Gadus macrocephalus) from the Strait of Georgia and the Strait of Juan de Fuca, 1945-84 by R. P Foucher( Book )

3 editions published in 1985 in English and held by 5 WorldCat member libraries worldwide

Reproductive biology of Pacific cod and English sole from the cruise of the FV BLUE WATERS to Hecate Strait, January 30 to February 11, 1989 by R. P Foucher( Book )

4 editions published in 1989 in English and held by 4 WorldCat member libraries worldwide

Results of the 4th cruise in a series in Hecate Strait to study the reproductive biology of Pacific cod and English sole. The study collected samples to determine gonosomatic index, sex ratio, size at 50% maturity, and ovary ripening stage for a description of the annual maturation cycle in both species. In addition, biological samples were taken to describe fecundity as a function of body weight and age for Pacific cod, and to preserve samples of the ovaries for histological preparation for microscopic examination of the progressing of oocyte development in English sole
Pacific cod tagging and stock monitoring off southwest Vancouver Island, February-March, 1979 : (Pacific Eagle groundfish cruises 79-1 and 79-2) by R. P Foucher( Book )

3 editions published between 1979 and 1980 in English and held by 4 WorldCat member libraries worldwide

Cruise of the F/V NUCLEUS, January 5-17, 1987 to Hecate Strait to study reproductive biology of Pacific cod and English sole by R. P Foucher( Book )

4 editions published in 1987 in English and held by 4 WorldCat member libraries worldwide

Report summarizing results of the second cruise in a series to investigate the reproductive biology of Pacific cod and English sole in Hecate Strait. In the first cruise, ovaries were collected from both species, in months throughout the year, for histological study. Ovaries were also collected from Pacific cod for estimation of fecundity. Fecundity has been previously estimated for Pacific cod in Hecate Strait in 1961. A further 581 female Pacific cod were sampled for maturity to gain further information on size at maturity. No English sole were found that contained developing eggs
Cruise of the FRV W.E. Ricker, November 2-13, 1987 to Hecate Strait to study reproductive biology of Pacific cod and English sole by A. V Tyler( Book )

3 editions published in 1988 in English and held by 4 WorldCat member libraries worldwide

Ovaries were obtained from Pacific cod and English sole from 3 grounds in Hecate Strait for histological examination of the ovarian cycle. Ovary weight vs. fish weight, and liver weight vs. fish weight relationships were fitted and graphed for both species. English sole were also sampled for fecundity from Horseshoe. Ageing structures (otoliths) were taken from English sole with the fecundity sample
