This book was released on 2021 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atlantic Menhaden (Brevoortia tyrannus) is an abundant forage fish species whose management has recently shifted from using single species reference points to ecological reference points. This type of management allows for the ecological role (e.g., supporting predators) of the species to be considered when making management decisions, and is part of a growing global movement towards ecosystem-based fisheries management. One model that aided in this transition from single species to ecological reference points was the Northwest Atlantic Continental Shelf (NWACS13) model created using Ecopath with Ecosim (Buchheister et al. 2017). Here, I updated and expanded the NWACS13 model with four years of additional data and used it to address three main objectives. First, I evaluated the effects of different Menhaden fishing mortality rates on the relative biomasses of modeled species groups using 50-year projections. Second, I examined whether single species biomass target reference points would be achieved for five focal species of management interest (Striped Bass, Bluefish, Weakfish, Spiny Dogfish, Atlantic Herring) under different fishing rates for Menhaden and the focal species. Third, I implemented bottom-up, primary production forcing in the ecosystem model to explore the long-term consequences on biomass and catch of a 3.5% and 6% decrease in phytoplankton biomass that represents a range of climate-change effects from the literature. Results indicate that ecological reference points behaved as they were designed, to push Striped Bass biomass toward its target. Nearshore piscivorous birds and pelagic sharks were identified as species of concern and were not included in less complex models. The inclusion of a primary production forcing function strengthened the relationship between Atlantic Menhaden and Striped Bass biomass in model projections, a key interaction evaluated in setting ecological reference points for Atlantic Menhaden. The inclusion of climate change projections identified disproportionate negative impacts on the biomass and catch of several species groups including Weakfish, Atlantic Cod, Striped Bass, Bluefish, and Spiny Dogfish. This model and study can contribute to fisheries management by identifying species or interactions of concern that are sensitive to Menhaden fishing mortality rates. This work contributes to Menhaden management by providing insight into the benefits of adding further complexity to models currently used for management decision making. More broadly, this work contributes to the ecosystem-based management movement and shows how climate impacts can be considered in making management decisions.

Available in PDF, EPUB and Kindle. Book excerpt: Ecosystem-based fishery management (EBFM) is rapidly becoming the default approach in global fisheries management. The clarity of what EBFM means is sharpening each year and there is now a real need to evaluate progress and assess the effectiveness and impacts. By examining a suite of over 90 indicators (including socioeconomic, governance, environmental forcing, major pressures, systems ecology, and fisheries criteria) for 9 major US fishery ecosystem jurisdictions, the authors systematically track the progress the country has made towards advancing EBFM and making it an operational reality. The assessment covers a wide range of data in both time (multiple decades) and space (from the tropics to the poles, representing over 10% of the world's ocean surface area). The authors view progress towards the implementation of EBFM as synonymous with improved management of living marine resources in general, and highlight the findings from a national perspective. Although US-centric, the lessons learned are directly applicable for all parts of the global ocean. Much work remains, but significant progress has already been made to better address many of the challenges facing the sustainable management of our living marine resources. This is an essential and accessible reference for all fisheries professionals who are currently practicing, or progressing towards, ecosystem-based fisheries management. It will also be of relevance and use to researchers, teachers, managers, and graduate students in marine ecology, fisheries biology, biological oceanography, global change biology, conservation biology, and marine resource management.

Book excerpt: Predicting Future Oceans: Sustainability of Ocean and Human Systems Amidst Global Environmental Change provides a synthesis of our knowledge of the future state of the oceans. The editors undertake the challenge of integrating diverse perspectives—from oceanography to anthropology—to exhibit the changes in ecological conditions and their socioeconomic implications. Each contributing author provides a novel perspective, with the book as a whole collating scholarly understandings of future oceans and coastal communities across the world. The diverse perspectives, syntheses and state-of-the-art natural and social sciences contributions are led by past and current research fellows and principal investigators of the Nereus Program network. This includes members at 17 leading research institutes, addressing themes such as oceanography, biodiversity, fisheries, mariculture production, economics, pollution, public health and marine policy. This book is a comprehensive resource for senior undergraduate and postgraduate readers studying social and natural science, as well as practitioners working in the field of natural resources management and marine conservation. Provides a synthesis of our knowledge on the future state of the oceans Includes recommendations on how to move forwards Highlights key social aspects linked to ocean ecosystems, including health, equity and sovereignty
