Book excerpt: Analysis of the geographical distribution of herring spawning in B.C. from 1937-86. The analysis was based on 20,000 records of spawning made annually for different regions of the B.C. coast. For each of 90 geographical subdivisions, tables are presented to show the annual frequency of spawns in 1 km segments, along with histograms showing the intensity of spawning in specific areas. Separate tables present a statistical summary of spawn records, including mean spawning dates and tables summarizing roe fishery activity from 1972-86 are shown for each location. A descriptive summary, including a classification of the ecological importance of herring spawning habitat, is presented for each area.

Available in PDF, EPUB and Kindle. Book excerpt: Pacific herring (Clupea pallasii) play a foundational role in human-ocean systems. While once abundant, herring have experienced declines and intermittent fisheries closures in British Columbia (BC) during the last century. I interviewed members of the Heiltsuk First Nation, and mapped their traditional ecological knowledge of the spatial distribution of observed herring spawns along the central coast of BC from the 1940s to the 2000s. The results show a marked contraction and aggregation in the distribution of spawns over time, with the total length of coastline with observed spawns declining at an average rate of 7.6% per decade. The concentration of spawns also shifted in space, with substantial declines on the exposed outer shores in the west of the region and the majority of recent spawns observed further inland to the east. In order to support resilient populations, fisheries management should account for such spatial characteristics and variation through time.

Download or read book Review of the 1989 90 British Columbia Herring Fishery and Spawn Abundance written by and published by . This book was released on 1991 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pacific herring migrate to inshore areas from offshore feeding grounds in the early fall and winter and then hold in sheltered bays and inlets in preparation for spawning in late winter and early spring. The food and bait fishery is conducted in November/December when the herring first move inshore and the fat content is high, and the sac-roe and spawn-on-kelp fisheries occur in March/April during the spawning season when gonad development is near or at maximum. When the herring have finished spawning, measurements of individual spawns are made to obtain estimates of abundance. This information is combined with data on catch and age composition to estimate the overall herring abundance and age class strength and to forecast the amount of herring that will return to spawn during the next year. This report presents information on the 1989/90 herring fishery and spawn abundance by district.

Download or read book Review of the 1991 92 British Columbia Herring Fishery and Spawn Abundance written by and published by . This book was released on 1993 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pacific herring (Clupea harengus pallasii) migrate to in-shore areas from offshore feeding grounds in the early fall and winter and then hold in sheltered bays and inlets in preparation for spawning in late winter and early spring. During this time, three major commercial herring fisheries occur; a food and bait fishery, a sac-roe fishery and a spawn-on-kelp fishery. The food and bait fishery takes place in November/December when the herring first move inshore and the fat content is high, while the sac-roe and spawn-on-kelp fisheries occur in March/April during the spawning season when gonad development is near or at maximum. This report presents the results of these fisheries over the past year. Methodology is included.
