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.

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.

Download or read book Considerations for Implementing an Adaptive Management Herring Rebuilding Strategy Using Local Interventions in BC written by Wanli Ou and published by . This book was released on 2014 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite widespread fisheries efforts to rebuild fisheries, the recovery of depleted stocks is still poorly understood. In British Columbia, researchers have been attempting to understand the factors limiting the recovery of Pacific herring (Clupea pallasii) stocks, which have experienced declines to below harvestable levels in the past decade. Adaptive management is a policy innovation, invented to address problems in natural resource management by treating management interventions as experiments and monitoring the system's feedbacks. I examine the institutional, social, and ecological considerations for implementing an adaptive management experimental program to rebuild herring stocks, through the use of two ongoing and proposed local management interventions. I highlight opportunities to overcome barriers to program implementation, and provide experimental design recommendations to evaluate the success of these interventions, given existing uncertainties about herring stock structure and variability. Implementing such a program could facilitate learning about how to rebuild Pacific herring populations and fisheries.
