This volume provides essential information on the origin and evolution of Greek rivers, as well as their ecological and anthropogenic characteristics. The topics covered include geomythology, biogeography, hydrology, hydrobiology, hydrogeochemistry, geological and biogeochemical processes, anthropogenic pressures and ecological impacts, water management - both in the antiquity and today - and river restoration. The book is divided into four parts, the first of which explores the importance of rivers for ancient Greek civilization and the natural processes affecting their evolution during the Holocene. In the second part, the hydrological, hydrochemical and biological features of Greek rivers and the unique biogeographical characteristics that form the basis for their high biodiversity and endemism are highlighted, while the third part comprehensively discusses the impacts of environmental pollution on the structure and function of Greek river ecosystems. In turn, the final part describes the current socio-economic factors in Greece that are affecting established water management practices, the application of ecohydrological approaches in restoring fragmented rivers, and the lessons learned from restoring aquatic ecosystems in general as a paradigm for understanding and minimizing anthropogenic impacts on water resources, at the Mediterranean scale. Given the breadth and depth of its coverage, the book offers an invaluable source of information for researchers, students and environmental managers alike.

Seas and oceans offer a wide range of temperature, pressure, light and chemical conditions thus allowing a wide diversity of marine organisms from shallow coastal waters to the deep ocean. These resources can be used to obtain new products and develop services, and in turn help to provide solutions to the challenges that affect our planet, including offering a sustainable supply of food and energy, new industrial materials and processes, new bioactive compounds, and new health treatments. Marine compounds have been identified as having antibacterial, anticoagulant, antifungal, antimalarial, antiprotozoal, antituberculosis, and antiviral activities. The major sources of these bioactive compounds are marine sponges, coelenterates, and microorganisms, followed by algae, echinoderms, tunicates, molluscs, and bryozoans. The discovery of bioactive compounds from marine samples is a hot topic considering the current need for sustainable use of marine resources. This book is a comprehensive overview of the analytical techniques employed in the discovery and characterization of bioactive compounds isolated from (all possible) marine samples and gives future perspectives of analytical methodologies. This overview includes an assessment of the sampling and preparation of extracts, the separation and isolation of bioactive compounds, their structural characterization and the application of bioassays in the discovery of bioactive compounds.

The first text to take a truly inter-disciplinary approach to critically examining the impacts of tourism on marine environments and coastal regions, focusing on the negative environmental impacts but also looking at the social and economic context of marine tourism and coastal zone management. The book sets tourism against the background of the crisis facing our oceans due to climate change and the effects of global warming. Tourism adds another layer of challenges for our marine environment, and its rapid growth globally means that these challenges have grown dramatically in recent years. We have seen a number of trends in the relationship between tourism and our oceans which pose a threat to the future of the marine environment and coastal communities. The Impact of Tourism on the Marine Environment looks at these trends in detail and tackles issues such as: * A critical evaluation of the cruise sector in terms of its impacts on the marine environment and the coastal destinations visited by cruise ships. * Marine wildlife watching and whether it is the enemy of conservation or its ally * The overall impact of tourism on waste, litter and plastics in the oceans. * The two-way relationship between climate change and global warming and marine environments and coastal tourist destinations * The effects of leisure activities such as diving and sea angling on the marine environment including coral reefs * The consumption of marine resources to meet tourist demand for seafood and souvenirs that deplete ocean resources * Natural and man-made disasters which have their origins in the oceans but have an impact on coastal tourist destinations * The challenges involved in the planning and management of tourism in marine environments and the impacts of the construction of new resorts and tourism infrastructure. * The debate over whether there is a need for regulation to control the impacts of tourism on our oceans or whether industry self-regulation is the best approach to take The book includes nearly forty mini-case studies from around the world which illustrate issues raised in the text. There are also two important 'opinion pieces' from Professor Harold Goodwin and Professor Michael Hall. A must-have text for students, researchers and practitioners looking at issues of sustainable tourism, tourism planning, environmental management, geography, marine conservation and corporate social responsibility.

This book contributes to the current discussion on global environmental changes by discussing modifications in marine ecosystems related to global climate changes. In marine ecosystems, rising atmospheric CO2 and climate changes are associated with shifts in temperature, circulation, stratification, nutrient input, oxygen concentration and ocean acidification, which have significant biological effects on a regional and global scale. Knowing how these changes affect the distribution and abundance of plankton in the ocean currents is crucial to our understanding of how climate change impacts the marine environment. Ocean temperatures, weather and climatic changes greatly influence the amount and location of nutrients in the water column. If temperatures and currents change, the plankton production cycle may not coincide with the reproduction cycle of fish. The above changes are closely related to the changes in radiative forcing, which initiate feedback mechanisms like changes in surface temperature, circulation, and atmospheric chemistry.

Marine fungi play a major role in marine and mangrove ecosystems. Understanding how higher fungi with their spectrum of cellulolytic and ligninolytic enzymes degrade wood tissue, while labyrinthuloids and thraustochytrids further contribute to the dissolved organic matter entering the open ocean is essential to marine ecology. This work provides an overview of marine fungi including morphology and ultrastructure, phylogeny, biogeography and biodiversity. Increasingly, biotechnology is also turning to these organisms to develop new bioactive compounds and to address problems such as decomposition of materials in the ocean and bioremediation of oil spills. These potential applications of marine fungi are also treated. In the light of massive marine oil spills in the past years, the importance of understanding marine fungi and their role in the food chain cannot be underestimated.

Jellyfish', a group that includes scyphomedusae, hydromedusae, siphonophores and ctenophores, are important zooplankton predators throughout the world's estuaries and oceans. These beautiful creatures have come to public attention as featured exhibits in aquaria and in news headlines as invaders and as providers of genes used in biomedical research. Nevertheless, jellyfish are generally considered to be nuisances because they interfere with human activities by stinging swimmers, clogging power plant intakes and nets of fishermen and fish farms, and competing with fish and eating fish eggs and larvae. There is concern that environmental changes such as global warming, eutrophication, and over-fishing may result in increased jellyfish populations. The literature reviews and research papers in this volume explore the interactions between jellyfish and humans. Papers cover the medical aspects of jellyfish stings, jellyfish as human food and jellyfish fisheries, interactions of jellyfish and fish, effects of environmental changes on jellyfish, effects of introduced ctenophores on the Black Sea ecosystem, factors causing increases or concentrations of jellyfish, and others aspects of jellyfish ecology. This is an important reference for students and professional marine biologists, oceanographers, fishery scientists, and aquarists.

The need for ion and water homeostasis is common to all life. For fish, ion and water homeostasis is an especially important challenge because they live in direct contact with water and because of the large variation in the salt content of natural waters (varying by over 5 orders of magnitude). Most fish are stenohaline and are unable to move between freshwater and seawater. Remarkably, some fishes are capable of life in both freshwater and seawater. These euryhaline fishes constitute an estimated 3 to 5% of all fish species. Euryhaline fishes represent some of the most iconic and interesting of all fish species, from salmon and sturgeon that make epic migrations to intertidal mudskippers that contend with daily salinity changes. With the advent of global climate change and increasing sea levels, understanding the environmental physiology of euryhaline species is critical for environmental management and any mitigative measures. This volume will provide the first integrative review of euryhalinity in fish. There is no other book that focuses on fish that have the capacity to move between freshwater and seawater. The different challenges of salt and water balance in different habitats have led to different physiological controls and regulation, which heretofore has not been reviewed in a single volume.

The coastal and ocean ecosystem is a significant feature of our planet and provides a source of food for much of life on Earth. Millions of species have been, and are still being discovered in the world's oceans. Among these zooplankton serve as secondary producers and are significant as they form pelagic food links and act as indicators of water masses. They constitute the largest and most reliable source of protein for most of the ocean's fishes. As such, their absence or depletion often affects fishery. In many countries, the decline in fishery has been attributed to reduced plankton populations. Furthermore, trillions of tiny copepods produce countless faecal pellets contributing greatly to the marine snow and therefore accelerating the flow of nutrients and minerals from the surface waters to the seabed. They are phylogenetically highly successful groups in terms of phylogenetic age, number of living species and success of adaptive radiation. A study of the basic and applied aspects of zooplankton would provide an index of the fishery potential and applications, offering insights into ocean ecology to safeguard food supplies and livelihoods of the millions of people living in coastal areas. For this reason, we need to understand all the facets of zooplankton as well as their interactions with atmosphere and other life forms, including human. In this context, this book discusses the basic and applied aspects of zooplankton, especially taxonomy, mosquitocidal activity, culture, analysis of nutritional, pigments and enzyme profile, preservation of copepods eggs, bioenrichment of zooplankton and application of zooplankton in sustainable aquaculture production, focusing on novel biofloc-copefloc technologies, and the impact of acidification and microplastics on zooplankton. Offering a comprehensive overview of the current issues and developments in the field of environmental and commercial applications, this book is a valuable resource for researchers, aquaculturists, environmental mangers wanting to understand the importance of zooplankton and develop technologies for the sustainable production of fish and other commodities to provide food and livelihoods for mankind.

New to this edition, this lab manual has been specially designed to help students learn more about marine life and their habits.

This work examines the waters of marine ports as unique integrated aquatic ecosystems. It regards marine ports as entities comprising components of natural and anthropogenic origin, including pelagic, periphytal and benthal subsystems. Using selected Black and Azov Sea ports as examples, the book discusses the hydrodynamics and water exchange, which are weakened in ports compared with open coastal zones. It reflects consequences of the presence of hydrobionts and the accumulation of organic matter, which are promoted by the variety of hard substrata and the absence of fishery. The book is divided into five main chapters. The first chapter describes the general characteristics of the marine ports at the northern coast of the Black and Azov Seas and their shipping channels. Chapters 2 to 4 discuss the main abiotic and biotic peculiarities of the pelagial, periphytal and benthal subsystems of those marine ports, and chapter 5 deals with tropho-dynamic processes in their ecosystems. A concluding section reflects recommendations how the ecosystems of ports in non-tidal seas may be ameliorated.

This is a reprint of the first revision of this classic. Originally published in 1953 as Fishery Bulletin #74 for the US Department of the Interior, Fish and Wildlife Service. The "Gulf of Maine" is defined as an area from the Nantucket Shoals and Cape Cod in the west to Cape Sable in the east. The aim of the book was to provide a handbook for the easy identification of the fishes that occur in the Gulf of Maine, with summaries of what is known about the distribution and relative abundance together with information on the life history of each species. The authors used the 150-fathom boundary as the arbitrary offshore boundary as this will exclude almost all "deep-sea" fishes, which are numerous in the basin of the open Atlantic. Combining information gleaned from the literature as well as surveys from a large number of cruises, the volume covers the Cyclostomes, cartilaginous fishes, torpedoes, skates and rays and the bony fishes. The descriptions are as non-technical as is compatible with scientific accuracy and are limited to external features that will aid in identification in the field.

This book compiles the latest findings in the field of marine and brackishwater aquaculture. It covers significant topics such as techniques of culture of live feeds (microalgae, rotifer, Artemia, marine copepod & polychaetes), while also highlighting vital themes like the culture and applications of free and marine sponge associated microbial probiotics, controlled breeding, seed production and culture of commercially important fin and shell fishes. Moreover, the book focuses on the breeding and culture of marine ornamental fishes, sea cucumber and sea urchin and discusses seaweeds culture, aqua feed formulation and nutrition, water quality management in hatchery and grow-out culture systems, fish disease diagnosis and health management and cryopreservation of fish gametes for sustainable aquaculture practices, all from a multidimensional perspective. The global fish production was 154 million tonnes in 2011 which more or less consisted of capture and culture fisheries (FAO, 2012). Roughly 80% of this is from inland-freshwater aquaculture and the remainder from capture fisheries in the marine and brackishwater sector. However, marine and brackishwater catches have recently begun to diminish due to overexploitation, climate change and pollution. The UNEP report affirmed that if the world remains on its current course of overfishing, by 2050, the ocean fish stock could become extinct or no longer commercially viable to exploit. In these circumstances, aquaculture is considered to be a promising sector to fulfill our future protein requirement. However, brackishwater and marine fish production now face serious challenges due to e.g. lack of quality fish seeds, feeds, poor water quality management and diseases. Fisheries and aquaculture sectors play a vital role as potential sources of nutritional security and food safety around the globe. Fish food is rich in protein, vitamins, phosphorous, calcium, zinc, selenium etc. In addition, fish contains omega-3 fatty acids, which help to prevent cardiovascular diseases. Fish food can also provide several health benefits to consumers. The omega 3 fatty acids found in fish can reduce the levels of LDL cholesterol (the "bad" cholesterol) and increase the HDL levels (the "good" cholesterol). Research conducted in Australia has proved that fish consumption can be used to cure hypertension and obesity. It is also reported that people who ate more fish were less prone to asthma and were able to breathe more easily. Omega 3 fish oil or fish consumption can help to prevent three of the most common forms of cancer: breast cancer, colon and prostate cancer. The omega 3 fatty acids present in fish or fish oil induce faster hair growth and prevent hair loss. Since most varieties of fish are rich in protein, eating fish helps to keep hair healthy. Furthermore, fish or fish oil helps in improving the condition of dry skin, giving it a healthy glow. It is useful in treating various skin problems such as eczema, psoriasis, itching, redness of skin, skin lesions and rashes. It is well known that eating fish improves vision and prevents Alzheimer's and type-2 diabetes, and can combat arthritis. Further, fish oil or fish is good for pregnant women, as the DHA present in it helps in the development of the baby's eyes and brain. It helps to avoid premature births, low birth weights and miscarriages. In addition, it is widely known that fish can be a good substitute for pulses in cereal-based diets for the poor. The global fish production was roughly 154 million tonnes in 2011 (FAO, 2012). It is estimated that by 2020 global fish requirements will be over 200 million tonnes; as such, innovative technological improvements are called for in order to improve the production and productivity in fisheries. In this context, this book provides valuable information for academics, scientists, researchers, government officials and farmers on innovative technological advances for sustainable fish production using aquaculture methods. The book identifies the main issues and trends in marine and brackishwater aquaculture from a global perspective in general and in the Indian context in particular. It includes 23 chapters written by prominent researchers from various institutes and universities across India, who address the latest aquaculture technologies with distinctive approaches to support academics, researchers and graduates in the fields of Fisheries, Aquaculture, Marine Science, Marine Biology, Marine Biotechnology, Zoology and Agricultural Sciences. Our thanks go to our contributors; we are confident that all readers will immensely benefit from their valued expertise in the field of marine and brackishwater aquaculture.

Each book has two main goals
1. Determine baseline concentrations of metals and metalloids in tissues of representative field populations of estuarine coastal, and open ocean organisms (Book 1: algae and macrophytes, protists, sponges, coelenterates, molluscs, crustaceans, insects, chaetognaths, annelids, echinoderms, and tunicates) (Book 2: elasmobranchs, fishes, reptiles, birds, mammals) and their significance to organism health and to the health of their consumers.
2. Synthesize existing information on biological, chemical, and physical factors known to modify uptake, retention, and translocation of each element under field and laboratory conditions. Recognition of the importance of these modifiers and their accompanying interactions is essential to the understanding of metals kinetics in marine systems and to the interpretation of baseline residue data.
