2021 - National Academies of Sciences, Engineering, and Medicine - Data and Management Strategies for Recreational Fisheries with Annual Catch Limits

 


"The collection of catch data on marine recreational fisheries is difficult, complex, and different from data collection for commercial fisheries. The complexity of recreational fisheries comes from the vast number of species, fishers, entry locations, fishing seasons, and recreational fishers’ objectives⎯from enjoying a day in nature to catching dinner. 

As the magnitude and relevance of recreational fisheries increase, so does the demand for better data collection systems.  In 2017, the National Marine Fisheries Service of the National Oceanic and Atmospheric Administration (NOAA), also known as NOAA Fisheries, requested that the National Academies of Sciences, Engineering, and Medicine, or “The National Academies,” review the Marine Recreational Information Program (MRIP). This national program provides recreational catch data to support the needs of fisheries scientists and managers who are responsible for conducting assessments of fish stocks and establishing fishing regulations to ensure the sustainable management and use of U.S. fisheries resources. The National Academies convened an ad hoc committee that assessed progress in updating marine recreational fisheries data collection through MRIP over the previous decade, and identified potential areas for improvements or modifications to the program that would increase data quality for sustainable fisheries management. That committee released the report Review of the Marine Recreational Information Program, which concluded that the difficulties of estimating recreational catches in an accurate, precise, and timely manner with sufficient spatio-temporal resolution to inform in-season monitoring and management against annual catch limits (ACLs) may result in management problems for recreational and mixed-use fisheries. These difficulties may also lead to an erosion of trust in the management system among recreational fisheries stakeholders. 

While NOAA Fisheries has made improvements to the MRIP program since 2017, questions remain regarding outstanding challenges limiting the extent to which current survey methods in each region meet the needs of the defined in-season management of recreational fisheries with ACLs. In some cases, adherence to ACLs requires short recreational fishing seasons, which complicates data collection, monitoring, and management. This observation is not new, and warrants the consideration of alternate approaches to optimize MRIP data and complementary data for in-season management.  In 2018, the Modernizing Recreational Fisheries Management Act underscored the many differences between commercial and recreational fisheries management, and called for a new National Academies study on how well the MRIP meets the needs of in-season management of fisheries with ACLs as well as how survey methods or management strategies might be modified to better meet those needs. The National Academies convened the Committee on Data and Management Strategies for Recreational Fisheries with Annual Catch Limits in 2020 to conduct this study. This report is a result of that effort. 

This report captures the collective wisdom of some of the nation’s leading experts in survey sampling and recreational fisheries data and management. I want to express my deep appreciation to every member of the committee for his or her attention, thoughtfulness, and hard work, as well as their wonderful collegiality. 

The committee is grateful to NOAA Fisheries for their responsiveness to the many questions and requests for information while developing this report. In particular, we thank the MRIP staff and Gordon Colvin for his guidance throughout the study process. The committee is also grateful to the many individuals who played a role in completing this study. The committee met seven times throughout the course of the study, and would like to extend its thanks to all the individuals from regional councils, NOAA Fisheries, state fisheries agencies, recreational and commercial fisheries organizations, environmental conservation organizations, and others who appeared before the full committee, or provided background information and discussed relevant issues. 

Lastly, the committee extends its sincere appreciation to our superb National Academies’ staff for their valuable support and many contributions to the project. Study Director Stacee Karras, Assistant Study Director Alexandra Skrivanek, and Senior Program Assistant Trent Cummings were instrumental in keeping the project on course and ensuring the timely completion of the report without compromising quality. Working with this team has been a pleasure and a privilege." (Luiz Barbieri, Committee Chair, Committee on Data and Management Strategies for Recreational Fisheries with Annual Catch Limits)

2018 - Gasol & Kirchman (Eds.) - Microbial ecology of the oceans 3ª Edição



"The first edition of Microbial Ecology of the Oceans was published almost 20 years ago, and the second edition reached the bookstores nearly 10 years ago. It is about time for a third edition. This one, like the second edition, is not a revision but really a new book. In addition to having new topics, the book has subjects that had been dealt with in previous versions but have been approached from a different point of view, usually by different authors. This third edition, however, has the same audience as the other two editions: advanced undergraduates, beginning graduate students, and colleagues from other fields wishing to learn about microbes and the processes they mediate in marine systems. As we discuss in Chapter 1, aquatic microbial ecology has become a well‐established discipline that is still growing in size and attracting practitioners from other disciplines. This book is for students and colleagues looking for an updated view of some aspects of the field, written at an accessible level. Although a multi‐authored book of limited size can never be a proper textbook, the various editions of the book—combined, can be used as one—with the additional advantage that together they reflect the evolution of the field (or so we hope). This edition does not replace the two previous ones even if some subjects have advanced more than others since 2000. Although some chapters of the previous editions might now seem old, most are still useful for a basic course in marine microbial ecology or microbial oceanography.

In the introductory chapter to the first edition, Kirchman and Williams argued that it probably would take much less than 20 years of work to fill another book titled Microbial Ecology of the Oceans. Well, two further editions have appeared in nearly 20 years, yet by far not all relevant issues are touched on by the three books, as we discuss in Chapter 1. A new edition is necessarily incomplete. Because only a few chapters can fit in a book like this one, we must necessarily select subjects that we believe relevant, that have clearly changed significantly in the last 10 years or that reflect new ways in which we see our science. We would be rewarded if the different views taken by the authors stimulate further innovative research. One disclaimer: This book is planktocentric. This probably reflects our training and interests and also the setting in which we work, surrounded by oceanographers and biogeochemists. We considered having chapters on the benthic habitat (there was one in the second edition), as well as special habitats like sea ice, polluted environments, hydrothermal vents, or the microbiomes of large eukaryotic plants and animals. But this would have increased the size of the book in unaffordable ways or would have been a partial view of a growing field (e.g., microbiomes).

In addition to presenting the science, we would like to contribute to how it is executed. We think the field is still very much compartmentalized. Often researchers focused on phytoplankton do not deal with bacteria or archaea, or those that have viruses as their target do not care much about what protist people do. In the same way, sponge microbiome people interact little with plankton ecologists, except when they have new methods in common. Some of the chapters in this third edition have a focus on bacteria or phytoplankton or viruses, but several are cross‐cutting and include both prokaryotes and eukaryotes, or because they are more biogeochemical, deal with several groups of organisms. We hope to contribute to breaking down the barriers between topics in marine microbial ecology.

Are textbooks still needed? Both editors of this book recently had to clean out their offices for renovation. We threw away whole collections of journals and hundreds of reprints. To (maybe) the despair of science historians, we threw away letters and preprints and submitted (and rejected!) versions of manuscripts, but neither of us threw out any relevant books, even textbooks from the last century. We hope the previous editions of Microbial Ecology of the Oceans, and this new one, will stand in libraries and remain in your office for years in the future even when renovation comes along.

We thank everyone that has been involved in this third edition, especially the authors that contributed manuscripts and the reviewers of the book syllabus and of the various chapters. In some cases, authors of this edition or of chapters in previous editions served as reviewers. In particular, we would like to thank Claudia Benitez‐Nelson, Alison Buchan, Craig Carlson, Matt Church, Byron Crump, Paul del Giorgio, Virgina Edgcomb, Kyle Edwards, Zoe Finkel, Hans‐Peter Grossart, Åke Hagström, Thomas Kiørboe, Emilio Marañón, Ramon Massana, Mark Moore, Mary Ann Moran, Mark Saito, Ruth‐Anne Sandaa, Marta Sebastián, Evelyn and Barry Sherr, Meinhard Simon, Osvaldo Ulloa, Daniel Vaulot, and Erik Wommack. We especially thank Clara Ruiz‐González for the figures in Chapter 1, and our students and colleagues (some contributed to compiling Table 1.1) for discussion about many aspects of the book."

2001 - Gibson et al. (Eds.) - Oceanography and Marine Biology - An Annual Review Volume 39



The thirty-ninth volume of this series contains eight reviews written by an international array of authors. As usual, the reviews range widely in subject and taxonomic and geographic coverage. The majority of articles were solicited but the editors always welcome suggestions from  potential  authors  for  topics  they  consider  could  form  the  basis  of  appropriate contributions. Because an annual publication schedule necessarily places constraints on the timetable for submission, evaluation and acceptance of manuscripts, potential contributors are advised to make contact at an early stage of preparation so that the delay between submission and publication is minimised. 

The editors again gratefully acknowledge the willingness and speed with which authors complied with the editors’ suggestions, requests and questions and the efficiency of the copy editor and publishers in ensuring the regular annual appearance of each volume. This year has seen a further change in the editorial team and it is a pleasure to welcome Dr R.J.A. Atkinson as a co-editor for the series.
