Book Description
This manual contains guidance on data collection methods for developing socio-economic indicators, and it can be used to facilitate and simplify reporting under international conventions and agreements on matters relating to the sustainable fisheries development. The methodologies can be applied to fisheries at many different levels, from individual fisheries and coastal management units to a global level, and it aims to encourage consistent use of statistical methods in data collection.

Book Description
The Second Advisory Roundtable on the Assessment of Inland Fisheries was convened in partnership with United States Geological Service (USGS), from 25 to 27 November 2019. It reviewed the progress of work that had been initiated as a response to the recommendations of the “Advisory Roundtable on the Assessment of Inland Fisheries” that was convened in partnership with the United States Geological Service (USGS) and Michigan State University (MSU) in FAO Rome, from 8 to 10 May 2018. The Second Roundtable covered two aspects of the assessment of inland fisheries. As its first task, the Roundtable reviewed a threat mapping framework developed by USGS and the University of Florida, which seeks to provide a robust assessment method for inland fisheries and the associated ecosystems/basins upon which they depend. This is intended to support the management of aquatic systems and the continued delivery of ecosystem services. The status map that the analysis provides is a visual (and quantifiable) relative indication of the levels of anthropogenic and natural environmental pressures to inland fisheries at the basin or sub-basin level. Five major threats to inland fisheries (and their 21 sub-threat categories) were scored according to global studies and modeling.

Book Description
The international journal Ecohydrology & Hydrobiology (E&H) has been created to promote the concept of Ecohydrology, which is defined as the study of the functional interrelations between hydrology and biota at the catchment scale. Ecohydrology extends from the molecular level to catchment-scale processes and is based on three principles: • framework (hydrological principle) - quantification and integration of hydrological and ecological processes at a basin scale; • target (ecological principle) - necessity of enhancing ecosystem absorbing capacity and ecosystem services; and • management tool (ecological engineering) – the use of ecosystem properties for regulation the interplay between hydrology and biota. The journal encourages the submission of manuscripts which adopt an integrative approach to aquatic sciences, explaining ecological and hydrological processes at a river-basin scale or propose practical applications of this knowledge. It will also consider papers in other hydrobiological fields. Especially welcome are papers on regulatory mechanism within biocenosis and the resistance and resilience of freshwater and costal zones ecosystems. There is no page charge for published papers. All submitted papers, written exclusively in English, should be original works, unpublished and not under consideration for publication elsewhere. All papers are peer-reviewed. The following types of papers are considered for publication in E&H: • original research papers • invited or submitted review papers, • short communications

Book Description
This handbook summarises the experience gained over recent years in fishery statistical development by the Fishery Information, Data and Statistics Unit of the FAO, and provides guidance for developing and implementing cost-effective and sustainable fishery surveys. The methodological and operational concepts discussed apply equally to marine and inland capture fisheries. The emphasis is placed on the understanding and interpretation of the statistics, rather than on the computations producing them.

Book Description
Brown Trout: Biology, Ecology and Management A comprehensive guide to the most current research, history, genetics and ecology of the brown trout including challenging environmental problems The brown trout is an iconic species across its natural European distribution and has been introduced throughout the World. Brown Trout offers a comprehensive review of the scientific information and current research on this major fish species. While the brown trout is the most sought species by anglers, its introduction to various waters around the world is causing serious environmental problems. At the same time, introduction of exogenous brown trout lineages threats conservation of native gene pools of populations in many regions. The authors summarize the important aspects of the brown trout’s life history and ecology and focus on the impact caused by the species. The text explores potential management strategies in order to maintain numerous damaged populations within its natural distributional range and to ameliorate its impacts in exotic environments. The authors include information on a wide-range of topics such as recent updates in population genetics, evolutionary history, reproductive traits and early ontogeny, life history plasticity in anadromous brown trout and life history of the adfluvial brown trout and much more. This vital resource: Contains the latest research on the biology and ecology of brown trout Includes information on phylogeography, genetics, population dynamics and stock management Spotlights the brown trout’s introduction to regions around the world and the serious environmental impacts Offers a comprehensive review of conservation and management techniques Written for salmonid scientists and researchers, fishery and environmental managers, and students of population genetics, ecology and population dynamics, Brown Trout explores the most recent findings on the history, ecology and sustainability of this much-researched species.

Book Description
The first book dedicated to describing the hydrology of water flow in lake systems, geared for limnologists and students of hydrology. With fresh water becoming a critical issue around the world, lake mass balance—the hydrology or water movement in lakes—is increasingly important to environmental studies and remediation projects. Unfortunately, lake hydrology is often only briefly covered in broader texts on hydrogeology and hydrology or is confined to specialized research papers. Lake Hydrology rigorously describes the hydrology of flow into and out of lake systems. Explaining the physical parameters that influence lake behavior, as well as the mathematics that describes these systems, this in-depth book fills an important niche in the literature of watershed science. This text • describes the physical structure and nature of drainage basins and explains the origin and classification of lakes • explores the hydrology of lake mass balance and storage as it pertains to lake stage, groundwater and lake bottom interaction, hypsometry, lake hydraulics, precipitation, surface flow, evaporation, and transpiration • provides models, practical information, and solutions for lake management or remediation planning utilizing basic data, including stage fluctuation, evapotranspiration, lake-bottom seepage, precipitation, and surface flow • uses examples from real-world long-term studies, including Utah's Great Salt Lake and Florida's Lake Jackson, a karstic lake system • examines the effect of storm events including the temporal and areal distribution of rainfall, and flow paths of water in the catchment from precipitation • includes an introduction to relevant scientific principles, such as dimensional analysis, the properties of water, and the hydrologic cycle Unlike most limnology texts, which emphasize lake ecology and biology, Lake Hydrology is designed to truly elucidate the hydrology of lake systems, especially as it relates to components of the hydrologic cycle. This book will greatly benefit professionals and researchers involved in lake management, remediation, or investigation of lake systems, and can be used as is or integrated within graduate and advanced undergraduate courses in limnology.
