Bathymetric relationships of principal groundfish shelf cohabitants off West Vancouver Island and in Queen Charlotte Sound, based on demersal-trawl landing records by S. J Westrheim( Book )

2 editions published in 2005 in English and held by 40 WorldCat member libraries worldwide

This report examines the bathymetric relationships of lingcod (Ophiodon elongatus), Pacific cod (Gadus macrocephalus), and rock sole (Lepidopsetta bilineata), based on investigation of data for 1960-95 from the British Columbia groundfish trawl fishery in Queen Charlotte Sound and the west coast of Vancouver Island. The analysis was initially based on five-fathom depth intervals which were selected on the basis of the quantity & consistency of the landings of the principal species. Conventional statistical tests are used to explore the significance of mean-depth differences among species and for individual species among multiple-species combinations
Species trends in relative biomass, occupied area and depth distribution for Hecate Strait assemblage surveys from 1984-2003 by Alison Sinclair( Book )

1 edition published in 2007 in English and held by 39 WorldCat member libraries worldwide

The Hecate Strait Assemblage Survey (HSAS) was initiated in 1984. The original intent was to describe groundfish species distributions in the area and to identify stable resident assemblages that would be amenable to multispecies production analysis and management. The survey was conducted approximately every two years with bottom trawl. This report summarizes the results from 11 bottom trawl surveys in Hecate Strait in terms of species relative biomass, area occupied, depth and spatial distribution. The utility of these indices for stock assessment and species at risk purposes is discussed.--Document
Final results of the September 1979 Dover sole tagging experiment in northern Hecate Strait, 1979-1999 by J Fargo( Book )

2 editions published in 2007 in English and held by 37 WorldCat member libraries worldwide

During September 21-26, 1979, 5146 Dover sole were tagged and released at two locations in Area 5D (Figure 1). Recovery results through 1984 were published in Fargo et al. (1985). We analyzed the final recovery information for the tagging through 1999. Time at liberty was 20 years for the last recovery, and 15 recoveries were at liberty at least 10 years. During 1979-99 recovery rates were not significantly different for the two tagging grounds. Incidence of recovered tags (nos/100t) was substantially larger in Area 5D than in Area 5E. Recovery rates generally varied directly with length at tagging. The sex ratio was similar for tagged fish recovered from the commercial fishery in the two Areas, but not so in samples taken from commercial landings. There was a differential bathymetric migration of the sexes, also demonstrated in earlier studies in U.S. waters. Namely, female Dover sole tagged in "shallow" water in Hecate Strait migrated during winter into "deep" water off the west coast of the Queen Charlotte Islands for spawning. The migration of males to deepwater spawning areas preceded that of females
A comparison of catch between research and commercial vessels during a trawl survey of Hecate Strait, May 30-June 13, 1996 by Jeff J Fargo( Book )

7 editions published between 1909 and 1997 in English and held by 35 WorldCat member libraries worldwide

In May-June 1996, bottom trawl surveys were conducted in Hecate Strait, British Columbia, using a research vessel and a commercial vessel chartered to replicated the hauls made by the research vessel. The surveys were performed to compare the catch rate and biological data for a typical commercial vessel with that for the research vessel to assess: how appropriate the research-vessel catch per unit effort indices are for stock assessment work; and the length-specific selectivity of commercial groundfish species under the current minimum mesh regulation in the Strait. This report presents the results of analysis comparing catch rate and biological data between the research vessel and the commercial vessel
English sole tagging in Hecate Strait, R/V G.B. Reed, June 6-24, 1983 by J Fargo( Book )

4 editions published in 1984 in English and held by 31 WorldCat member libraries worldwide

English sole (Parophrys vetulus) were tagged aboard the research vessel G.B. REED in Hecate Strait during June 1983. The primary purpose of the tagging experiment was to validate age determination methods for the species. Tagging took place on 3 major fishing grounds in International Areas 5C and 5D. A total of 5376 fish were tagged, injected with oxytetracycline (intramuscular) for age validation, and released. Immediate post-tagging mortality for the experiment was estimated at 0.01. Secondary activities included collecting length-weight data for English sole, collecting data on Pacific cod (Gadus macrocephalus) size and age composition, vertical water temperature profiles, vertical and surface plankton tows and sampling bottom sediment types
Groundfish stock assessments for the west coast of Canada in 1994 and recommended yield options for 1995 by Margarita Stocker( Book )

10 editions published between 1991 and 1995 in English and held by 18 WorldCat member libraries worldwide

Stock assessments and yield options are developed for the Pacific coast of Canada for lingcod, Pacific cod, petrale sole, Dover sole, rock sole, English sole, arrowtooth flounder, sablefish, Pacific hake, spiny dogfish, walleye pollock, Pacific ocean perch, yellowmouth rockfish, rougheye rockfish, redstripe rockfish, silvergray rockfish, yellowtail rockfish, canary rockfish, quillback rockfish, copper rockfish, yelloweye rockfish, hagfish, and Pacific halibut. A number of analytical methods have been employed in these assessments, like surplus production analysis, virtual population analysis, several variants of sequential age-structured analyses, dynamic pool models and depletion estimators. Biological objectives are the only consideration for these assessments and yield options. Yield options and recommendations on catch limitations and other management measures to achieve biological objectives are made to the fishery managers of Offshore Division of Fisheries Branch (Pacific Region). Alternative options allow managers to consider high risk and low risk yields in relation to a stock's potential productivity

Turbot stock assessment for 2001 and recommendations for management in 2002 by Jeff Fargo( Book )

5 editions published in 2001 in English and held by 5 WorldCat member libraries worldwide

This paper summarizes results of analysis of biological data, research survey data, and observer data for turbot (Atheresthes stomias), an important component of the British Columbia trawl fishery. It includes basic information on turbot biology and an overview of the data sources. Results discuss biological statistics (length/weight & length/age relationships, maturity, natural mortality, size & age composition, total mortality), catch per unit effort, catch by region, annual landing & discard catches, trends in catch rates as investigated using four general linear models, and biomass. The final section makes recommendations regarding fishery management
Flatfish stock assessments for the west coast of Canada for 1998 and recommended yield options for 1999 by J Fargo( Book )

3 editions published in 1999 in English and held by 4 WorldCat member libraries worldwide

Presents interim fishery assessments for various sole species off the west coast of Canada for 1997. Discussion is included regarding landing statistics and stock status. Yield options and recommendations are given for the west coast of Vancouver Island (Areas 3C and 3D), Queen Charlotte Sound (Areas 5A and 5B), and Hecate Strait (Areas 5C-E). For Hecate Strait, catch-age analyses and fishing rate reference points are also discussed
Stock assessment of rock sole and English sole in Hecate Strait for 2000/2001 by J Fargo( Book )

5 editions published in 2000 in English and held by 2 WorldCat member libraries worldwide

In this document, biological information is summarized and the results of catch-age analysis for stocks of rock sole and English sole in Hecate Strait are presented. A state space catch-age model is used to reconstruct stock history for both species. The results of the catch-age analysis are compared to those obtained using swept-area expansions of commercial and research survey catch rate data. Yield recommendations are estimated by applying target fishing mortality reference points to the most current estimates of biomass. This information is synthesized to provide advice to managers on harvest levels for the 2001/2002 fishing year
