This book was released on 2019 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Fisheries and Oceans Canada (DFO) has committed to renewing the current management framework to address a range of challenges facing Pacific Herring stocks and fisheries in British Columbia. Renewal of the management framework includes conducting a Management Strategy Evaluation (MSE) process to evaluate the performance of candidate management procedures against a range of hypotheses about uncertain stock and fishery dynamics. The purpose of the evaluation is to identify management procedures that provide acceptable outcomes related to conservation and fishery management objectives. Selection of a preferred management procedure for each DFO fisheries management area is an iterative process conducted with the participation of First Nations, the fishing industry, government and non-government organizations"--Context, pages [1]-2.

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.

This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pacific herring (Clupea pallasi) play a fundamental ecological and socio-economic role in marine ecosystems and have exhibited declining trends in British Columbia, Canada, over the past decade. The rate of herring egg loss following spawning events is a key parameter used to estimate population productivity, however, it is highly uncertain. We quantified the magnitude, spatial variation and mechanisms driving egg loss along BC's Central Coast using observational surveys and an experiment. Depending on the modeling approach, we estimated regional egg loss rates (Z) ranging from 0.152 ± 0.022 to 0.177 ± 0.027, the equivalent of 59-75% eggs loss over 6.8 days, the average lag between spawn deposition and survey. Loss rates varied by 4.5 orders of magnitude among sites. Spawn area was found to positively influence egg loss rates based on our observational study, while evidence from our experiment suggests that predation and habitat type were strong drivers of loss. Modeling approach, parameter uncertainty, and site-level variability in egg loss rates need to be accounted for when estimating Pacific herring abundance and its associated uncertainty.
