Available in PDF, EPUB and Kindle. Book excerpt: Developing accurate methods to survey fish is of vital importance to the monitoring of our marine ecosystems and establishing a basis for evaluating environmental anthropogenic change. Underwater video is a popular survey method that can avoid several limitations associated with underwater visual censuses (UVC), most notably, variable response to divers. Baited underwater video (BUV) is a commonly used survey method that avoids diver influence and yields statistically powerful results. However, the obtrusive nature of some BUV systems may cause similar behavioural responses to those reported for UVC methods. This study compares the relative densities of snapper Pagrus auratus inside and outside a marine reserve as measured using BUV, baited ‘stealth’ video (BSV), and an inconspicuous unbaited underwater video (UUV) to determine the most appropriate method for estimating abundances. An unbaited BUV frame (UBF) was used to test whether BUV underestimates densities of larger snapper in fished areas due to the presence of an obtrusive BUV frame. This study also presents a method for generating absolute density estimates using footage from a stationary video camera. Underwater video surveys were conducted inside and outside the Cape Rodney to Okakari Point Marine Reserve in north-eastern New Zealand from May to September 2016. Relative densities (expressed as reserve:non-reserve ratios) for legal (≥ 300mm) snapper were much higher for BUV and UBF compared to UUV and BSV. Proportions of larger fish sampled by the different methods were similar inside the reserve, but differed markedly outside the reserve, confirming the notion that BUV undersamples larger fish in non-reserve areas due to their wariness of the BUV structure, and therefore overestimates the “reserve effect”. A hump-shaped distribution of abundance shown by UUV and BSV suggests a higher reserve abundance is due to a “reserve effect” rather than a behavioural bias associated with BUV. A lack of a plateau suggests a larger reserve is needed to fully protect snapper populations. Using the new method developed for stationary video analysis, this study provides the first estimates of snapper absolute density and biomass per unit area on a temperate reef system inside and outside a marine reserve.

Book excerpt: This book gives a start-to-finish overview of the whole Fish4Knowledge project, in 18 short chapters, each describing one aspect of the project. The Fish4Knowledge project explored the possibilities of big video data, in this case from undersea video. Recording and analyzing 90 thousand hours of video from ten camera locations, the project gives a 3 year view of fish abundance in several tropical coral reefs off the coast of Taiwan. The research system built a remote recording network, over 100 Tb of storage, supercomputer processing, video target detection and tracking, fish species recognition and analysis, a large SQL database to record the results and an efficient retrieval mechanism. Novel user interface mechanisms were developed to provide easy access for marine ecologists, who wanted to explore the dataset. The book is a useful resource for system builders, as it gives an overview of the many new methods that were created to build the Fish4Knowledge system in a manner that also allows readers to see how all the components fit together.

Available in PDF, EPUB and Kindle. Book excerpt: Deep learning (DL), mainly composed of deep and complex neural networks such as recurrent network and convolutional network, is an emerging research branch in the field of artificial intelligence and machine learning. DL revolution has a far-reaching impact on all scientific disciplines and every corner of our lives. With continuing technological advances, marine science is entering into the big data era with the exponential growth of information. DL is an effective means of harnessing the power of big data. Combined with unprecedented data from cameras, acoustic recorders, satellite remote sensing, and large model outputs, DL enables scientists to solve complex problems in biology, ecosystems, climate, energy, as well as physical and chemical interactions. Although DL has made great strides, it is still only beginning to emerge in many fields of marine science, especially towards representative applications and best practices for the automatic analysis of marine organisms and marine environments. DL in nowadays' marine science mainly leverages cutting-edge techniques of deep neural networks and massive data which collected by in-situ optical or acoustic imaging sensors for underwater applications, such as plankton classification and coral reef detection. This research topic aims to expand the applications of marine science to cover all aspects of detection, classification, segmentation, localization, and density estimation of marine objects, organisms, and phenomena.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents key conclusions about the controversial killing of thousands of dolphins each year during tuna fishing in the eastern tropical Pacific. Dolphins drown in nets that are set to catch yellowfin tuna, which tend to swim beneath dolphin herds. After 20 years of intense debate among environmentalists, the tuna industry, and policymakers, this fatal by-product of tuna fishing remains a high-profile public issue. Dolphins and the Tuna Industry provides a neutral examination of the scientific and technical questions at the core of the problem. Recommendations for solutions are offered in two areas: developing new techniques that promise to reduce dolphin mortality with the existing purse-seine method of tuna fishing, and developing entirely new methods of finding tuna that are not swimming with dolphins. Dolphins and the Tuna Industry provides a comprehensive, highly readable overview of the dolphin-tuna controversy, useful to experts and newcomers to the issue. It explores the processes of tuna fishing and dolphin mortality, the status of the tuna industry, and the significant progress made in reducing dolphin mortality through modifications in fishing practice. The volume includes: An overview of U.S. laws and policies relating to tuna and dolphins. An illustrated look at how tuna fishing crews use their equipment, focusing on the purse seine, which is the method most economical to the industry but most deadly to the dolphins. An overview of what is known about tuna and dolphin populations and the remarkable bond between them. A step-by-step description of the fishing process and efforts to let dolphins escape from the nets. An analysis of possible approaches to reducing dolphin kill, including more stringent regulatory approaches and incentives for the tuna industry. This book will be indispensible to environmental and animal protection groups, tuna fishing crews and processors, companies that market tuna products, policymakers, regulators, and concerned individuals.

Available in PDF, EPUB and Kindle. Book excerpt: Quantitative modeling methods have become a central tool in the management of harvested fish populations. This book examines how these modeling methods work, why they sometimes fail, and how they might be improved by incorporating larger ecological interactions. Fisheries Ecology and Management provides a broad introduction to the concepts and quantitative models needed to successfully manage fisheries. Walters and Martell develop models that account for key ecological dynamics such as trophic interactions, food webs, multi-species dynamics, risk-avoidance behavior, habitat selection and density-dependence. They treat fisheries policy development as a two-stage process, first identifying strategies for varying harvest in relation to changes in abundance, then finding ways to implement such strategies in terms of monitoring and regulatory procedures. This book provides a general framework for developing assessment models in terms of state-observation dynamics hypotheses, and points out that most fisheries assessment failures have been due to inappropriate observation model hypotheses rather than faulty models for ecological dynamics. Intended as a text in upper division and graduate classes on fisheries assessment and management, this useful guide will also be widely read by ecologists and fisheries scientists.

Available in PDF, EPUB and Kindle. Book excerpt: This book explores how we can solve the urgent problem of optimizing the use of variable, uncertain but finite fisheries resources while maintaining sustainability from a marine-ecosystem conservation perspective. It offers readers a broad understanding of the current methods and theory for sustainable exploitation of fisheries resources, and introduces recent findings and technological developments. The book is divided into three parts: Part I discusses fish stock dynamics, and illustrates how ecological processes affecting life cycles and biological interactions in marine environments lead to fish stock variability in space and time in major fish groups; small pelagic fish, demersal fish and large predatory fish. These insights shed light on the mechanisms underlying the variability in fish stocks and form the essential biological basis for fisheries management. Part II addresses the technologies and systems that monitor changes in fisheries resources and marine ecosystems using two approaches: fishery-dependent and fishery-independent data. It also describes acoustic surveys and biological sampling, as well as stock assessment methods. Part III examines management models for effectively assessing the natural variability in fisheries resources. The authors explore ways of determining the allowable catch in response to changes in stock abundance and how to incorporate ecological processes and monitoring procedures into management models. This book offers readers a broad understanding of sustainable exploitation as well as insights into fisheries management for the next generation.

Book excerpt: During the last decade, there has been a shift in the governance and management of fisheries to a broaderapproach that recognizes the participation of fishers, local stewardship, and shared decision-making.Through this process, fishers are empowered to become active members of the management team,balancing rights and responsibilities, and working in partnership with government. This approach iscalled co-management.This handbook describes the process of community-based co-management from its beginning, throughimplementation, to turnover to the community. It provides ideas, methods, techniques, activities, checklists,examples, questions and indicators for the planning and implementing of a process of community-basedco-management. It focuses on small-scale fisheries (freshwater, floodplain, estuarine, or marine) indeveloping countries, but is also relevant to small-scale fisheries in developed countries and to themanagement of other coastal resources (such as coral reefs, mangroves, sea grass, and wetlands). Thishandbook will be of significant interest to resource managers, practitioners, academics and students ofsmall-scale fisheries.

Book excerpt: This technical reference applies to monitoring situations involving a single plant species, such as an indicator species, key species, or weed. It was originally developed for monitoring special status plants, which have some recognized status at the Federal, State, or agency level because of their rarity or vulnerability. Most examples and discussions in this technical reference focus on these special status species, but the methods described are also applicable to any single-species monitoring and even some community monitoring situations.We thus hope wildlife biologists, range conservationists, botanists, and ecologists will all find this technical reference helpful.

Book excerpt: Over the last decade, the study of shark biology has benefited from the development, refinement, and rapid expansion of novel techniques and advances in technology. These have given new insight into the fields of shark genetics, feeding, foraging, bioenergetics, imaging, age and growth, movement, migration, habitat preference, and habitat use. This pioneering book, written by experts in shark biology, examines technologies such as autonomous vehicle tracking, underwater video approaches, molecular genetics techniques, and accelerometry, among many others. Each detailed chapter offers new insights and promises for future studies of elasmobranch biology, provides an overview of appropriate uses of each technique, and can be readily extended to other aquatic fish and marine mammals and reptiles. Including chapter authors who were pioneers in developing some of the technologies discussed in the book, this book serves as the first single-source reference with in-depth coverage of techniques appropriate for the laboratory and field study of sharks, skates, and rays. It concludes with a unique section on Citizen Science and its application to studies of shark biology. This is a must-read for any marine biologist or scientist working in the field of shark biology, as well as marine biology students and graduates.
