Available in PDF, EPUB and Kindle. Book excerpt: Tradicionaly recreational fishery management has focused on dynamics of individual fish populations. Attempts to improve fish populations center on manipulations of harvest or the population itself. However, outcomes of fishery management actions have been difficult to forecast. Ecological processes within fish communities and angler responses can produce unanticipated effects. This thesis documents my research on these processes in Lake Mendota to make fishery management a more holistic, predictive science. A food web manipulation began in 1987. This project used several fishery management tools to increase the biomass of piscivorus gamefish to evaluate food web manipulation as a water quality management tool. Forecasting and measuring direct and indirect effects of the manipulation were important objetives. To forecast how management would affect piscivore populations, and their consumption of prey, I combined two computer models: an age-structured population model and a bioenergetics model. This technique predicted how size, abundance, and consumption of piscivores changed with stocking rates and sire limits. A walleye stocking program that yielded 8,000 yearling/year doubled consumption demand; adding a 381-mm minimum size limit achieved another 50% increase. To predict consequences of piscivore management for prey populations, I studied predador and prey fish populations. Highley variable prey recuitment made forecasting impacts of piscivory difficult. Based on historic recruitment patterns, enhanced walleye populations could consume 65-100% of young-of-year perch biomass produced in low recruitment years. When recruitment was high walleyes consumed less than 5% of the biomass. Translating predicted piscivore consumption into perch dynamics was accomplished by incorporating prey recruitment uncertainty. Angler response to piscivore enhancements was intense. Angler effort increased four-fold and harvest rates doubled to 60% per year. As a result, forescasts of piscivore consumption demand and the effectiveness of food web manipulation dependend heavily on responses of sport anglers to piscivore populations. Hence, a better understanding of angler dynamics was required before ecological effects of fishery management actions could be predicted. I developed a predatory-prey model to study angler-piscivore interactions. This approach linked angler and fish dynamics, and provided the means to incorporate fish, anglers, and management actions within one framework.

Book excerpt: There is increasing recognition of the sociocultural, economic, and ecological significance of recreational fishing as a fundamental element of the global wild capture fisheries. In New Zealand, recreational fishing is a very popular activity that many New Zealanders identify with, and that provides a variety of social, cultural and economic benefits for New Zealanders. Despite the significance of the recreational fishing sector as a resource user and contributor to fisheries impacts, it has gained little attention within fisheries management in New Zealand. Using the Hauraki Gulf as a case study, this research investigates the efforts to manage the New Zealand recreational fisheries sector within the current centralised management regime. To ensure the future sustainability of the fisheries resources and the health of the marine ecosystem, this research argues the importance of integrating the recreational fisheries sector into fisheries management. This involves examining current fisheries management in New Zealand, specifically the Quota Management System (QMS), and factors affecting the integration of the recreational sector. This research also considers the potential of Ecosystem Based Management (EBM) as a holistic approach to provide for the interests, needs and values of all stakeholders while also maintaining the health and function of the marine ecosystem. To achieve the research objectives, a qualitative methodology was adopted. In addition to the case study, key methods employed for this research were semi-structured interviews with recreational fishers and other stakeholders, and questionnaires with recreational fishers. The key findings highlight the importance of understanding the complex and dynamic nature of the sector so as to improve management of the sector. The research also indicates that participation and involvement of the recreational sector in fisheries management would remain limited if the legislative rights of the recreational sector under the Fisheries Act were not addressed and the distrust recreational fishers have towards the commercial sector and government was not resolved. Finally, the successful integration of the recreational sector also depends on the ability of recreational fishers to organise themselves and resolve their internal issues. The failure to do so would most likely see the continuation of current centralised fisheries management regime, where recreational fishers remain reliant on the voting booths to make their voices heard, and their direct influence on decision making remains limited.

Download or read book Holistic Approach to Ecosystem Based Fisheries Management written by Francisco Arreguín-Sánchez and published by Springer Nature. This book was released on 2022-03-30 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides cutting-edge scientific idea and novel concepts on the ecosystem-based approach to fisheries management. It begins by reviewing the scientific fundamentals and problems currently faced by conventional fisheries science, based on population dynamics. In turn, it reviews the theoretical basis of ecosystem dynamics, including selected ecosystem indicators. Surplus production and balanced harvests are discussed in the ecosystem dynamics context. Several ecosystem-holistic indicators are described, but particular emphasis is placed on two: the noxicline (gain in entropy due to loss of biomass) and resilience, which are expressed as ecosystem (holistic) points of reference for defining allowable harvest rates. Both biological (population) and ecosystem (holistic) points of reference are subsequently analyzed in the context of fisheries management and conservation. An adaptability concept is also discussed as a management policy for facing climate change. In closing, the concepts presented are applied to six study cases involving a range of different ecosystems and fisheries.

Download or read book Evolving Approaches to Managing Marine Recreational Fisheries written by Vishwanie Maharaj and published by Lexington Books. This book was released on 1955-01-01 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each year, thirteen million anglers enjoy the sport of saltwater angling in the United States, generating an estimated $30 billion in sales and supporting nearly 350,000 jobs. Recreational saltwater fishing, however, can significantly impact species of concern-species overfished or experiencing overfishing. Traditional angling controls—bag and size limits and restricted seasons—have fallen short in controlling fishing impacts and reducing conflicts among fishing and non-fishing interests. Evolving Approaches to Managing Marine Recreational Fisheries offers ways of overcoming such problems while providing anglers and the recreational service industry greater regulatory flexibility to enjoy the fruits of sportfishing. It features fourteen internationally recognized fishery experts presenting the pros and cons of using individual fishing quotas (IFQs), game tags, and angler management organizations (AMOs) in managing marine recreational fisheries, presenting both theoretical and practical solutions to help move recreational fisheries management to a new and improved level.

This book was released on 2022-04-21 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine recreational fishing is a popular activity enjoyed by more than 9 million Americans annually and is a driver of the American ocean-or blue-economy. To ensure that fish populations are not overexploited, the NOAA Fisheries' Marine Recreational Information Program (MRIP) monitors recreational catch through a variety of in-person, telephone, mail-in, and other surveys. NOAA Fisheries' management of recreational catch also must take into account annual catch limits (ACLs) established to prevent overfishing for all managed species in federal waters. While MRIP has worked to improve recreational catch surveys over the past decade, the surveys were never designed to meet the demands of in-season management of ACLs. In some cases, estimates of harvest have triggered accountability measures such as early season closures and reductions in future recreational ACLs, which have been a source of contention with the recreational fishing community. This report presents approaches for optimizing MRIP data and complementary data for in-season management and considers alternatives for managing recreational fisheries with ACLs to better serve both social and economic management objectives.
