Available in PDF, EPUB and Kindle. Book excerpt: Harvest of Fish and Wildlife: New Paradigms for Sustainable Management unites experts in wildlife and fishery sciences for an interdisciplinary overview of harvest management. This book presents unique insights for embracing the complete social-ecological system to ensure a sustainable future. It educates users on evolutionary and population dynamics; social and political influences; hunter and angler behavior; decision processes; impacts of regulations; and stakeholder involvement. Features: Written by twenty-four teams of leading scientists and managers. Promotes transparent justification for fishing and hunting regulations. Provides examples for integrating decision making into management. Emphasizes creativity in management by integrating art and science. This book appeals to population biologists, evolutionary biologists and social scientists. It is a key resource for on-the-ground managers and research scientists developing harvesting applications. As the book’s contributors explain: “Making decisions that are robust to uncertainty...is a paradigm shift with a lot of potential to improve outcomes for fish and wildlife populations.” –Andrew Tyre and Brigitte Tenhumberg “Temporal shifts in system states...must somehow be anticipated and dealt with to derive harvest policies that remain optimal in the long term.” –Michael Conroy “Proactive, effective management of sportspersons...will be essential in the new paradigm of harvest management.” –Matthew Gruntorad and Christopher Chizinski

This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of offspring production (recruitment) is fundamental to understanding and forecasting the dynamics of a population. In this thesis, I focus on two demographic characteristics of fish stocks that are important to recruitment: population density and age structure. First, populations produce more recruits at low density, but quantifying this response has proven difficult. Using data from hundreds of populations of walleye (Sander vitreus), an economically important freshwater fish, I demonstrate that the growing-degree-day metric (a temperature index) is better than age at explaining variation in density-dependent growth and maturity both within and among populations. I then incorporate multi-lake measures of density-dependent life history change into a temperature-based biphasic model of growth and reproduction to predict sustainable rates of mortality for walleye throughout most of their range. Second, the age (or size) structure of a population may also affect recruitment because of positive effects of maternal age on offspring production and survival; however, evidence for these 'maternal influences' on recruitment is limited. Using both an analytical model and a meta-analysis of stock-recruitment data from 25 species of exploited marine fish, I show that (i) maximum reproductive rate increased with the mean age of adults in a population, and (ii) the importance of age structure increased with a species' longevity. I then demonstrate a similar effect of maternal influences on reproductive rate in a detailed study of Lake Erie walleye. By highlighting the importance of fisheries-induced demographic change to recruitment, this thesis provides insight into past and present failures. However, it also demonstrates clearly the benefits of proactive management strategies that (i) identify and respect the limits of exploitation, (ii) protect from exploitation reproductively valuable individuals---principles that apply generally to any freshwater, marine, or terrestrial species that is of recreational, commercial, or conservation value.

Download or read book Estimating Movement with a Spatially-explicit Stock Assessment Model of Eastern Bering Sea Walleye Pollock, Theragra Chalcogramma written by Sara Elizabeth Miller and published by . This book was released on 2007 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The standard Eastern Bering Sea (EBS) walleye pollock (Theragra chalcogramma) stock assessment model has no spatial dimension. To advance the understanding of EBS walleye pollock movements and spatial structure on finer temporal and spatial scales, a spatially explicit migration model of EBS walleye pollock was developed. However, there are no estimates of movement rates for this population. Using standard sample size formulae in a Petersen-type experiment, we showed that only a moderate mark-recapture program [minimum number of tags for ages-1 + was 9,475 (all sectors included) and 20,924 (only catcher-vessel shoreside sector included)] is needed to estimate abundance. Given these sample size requirements determined for abundance estimation, the Darroch method was used to estimate movement parameters between two regions, the northwest (NW) and southeast (SE) EBS in a simple compartment model. Directed movement could be reasonably estimated with Monte Carlo simulation. To develop the EBS walleye pollock age-structured movement model, the standard stock assessment model was extended into a two-region (NW and SE EBS), two-season, age-specific movement model. Movement could be estimated from disaggregated data without mark-recapture information, but with low precision. However, the uncertainty indicates that a mark-recapture study is needed before such a model could be applied for management applications"--Leaf iii.
