Fish Swimming

Among the fishes, a remarkably wide range of biological adaptations to diverse habitats has evolved. As well as living in the conventional habitats of lakes, ponds, rivers, rock pools and the open sea, fish have solved the problems of life in deserts, in the deep sea, in the cold antarctic, and in warm waters of high alkalinity or of low oxygen. Along with these adaptations, we find the most impressive specializations of morphology, physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins, sailfish and warm-blooded tunas, air-breathing in catfish and lung fish, parental care in the mouth-brooding cichlids and viviparity in many sharks and toothcarps. Moreover, fish are of considerable importance to the survival of the human species in the form of nutritious, delicious and diverse food. Rational exploitation and management of our global stocks of fishes must rely upon a detailed and precise insight of their biology. The Chapman & Hall Fish and Fisheries Series aims to present timely volumes reviewing important aspects of fish biology. Most volumes will be of interest to research workers in biology, zoology, ecology and physiology but an additional aim is for the books to be accessible to a wide spectrum of non-specialist readers ranging from undergraduates and postgraduates to those with an intrerest in industrial and commercial aspects of fish and fisheries.

Set in Tokyo over the course of one night, Aki and Hiro have decided to be together one last time in their shared flat before parting. Their relationship has broken down after a mountain trek during which their guide died inexplicably. Now each believes the other to be a murderer and is determined to extract a confession before the night is over. Who is the murderer and what really happened on the mountain? In the battle of wills between them, the chain of events leading up to this night are gradually revealed in a gripping psychological thriller that keeps the reader in suspense to the very end.

Low-level river crossings, including culverts, are important for delivering a range of valuable socioeconomic services, including transportation and hydrological control. These structures are also known to have negative impacts on freshwater river system morphology and ecology, including the blockage of upstream fish passage, particularly small-body-mass fish species. Given the enormous environmental problems created by road crossings, new hydraulic engineering guidelines are proposed for fish-friendly multi-cell box culvert designs. The focus of these guidelines is on smooth box culverts without appurtenance, with a novel approach based upon three basic concepts: (I) the culvert design is optimized for fish passage for small to medium water discharges, and for flood capacity for larger discharges, (II) low-velocity zones are provided along the wetted perimeter in the culvert barrel, and quantified in terms of a fraction of the wetted flow area where the local longitudinal velocity is less than a characteristic fish speed linked to swimming performances of targeted fish species, and (III) the culvert barrel is smooth, without any other form of boundary treatment and appurtenance. The present monograph develops a number of practical considerations, in particular relevant to box culvert operations for less-than-design discharges. It is argued that upstream fish passage capabilities would imply a revised approach to maintenance, in part linked to the targeted fish species. This reference work is authored for civil and environmental engineers, as well as biology and ecology scientists interested in culvert design. While the book is aimed to professionals, the material is also lectured in postgraduate courses and in professional short courses.

This book examines the global, local, and specific environmental factors that facilitate illegal fishing and proposes effective ways to reduce the opportunities and incentives that threaten the existence of the world's fish. Humans are deeply dependent on fishing—globally, fish comprise 15 percent of the protein intake for approximately 3 billion people, and 8 percent of the global population depends on the fishing industry as their livelihood. The global fishing industry is plagued by illegal fishing, however, and many highly commercial species, such as cod, tuna, orange roughy, and swordfish, are extremely vulnerable. Through criminological analysis, The Last Fish Swimming emphasizes the importance of looking at specific environmental factors that make illegal fishing possible. It examines such factors as proximity to known ports where illegally caught fish can be landed without inspection (i.e., ports of convenience), fisheries monitoring, control and surveillance efforts, formal surveillance, and resource attractiveness in 53 countries that altogether represent 96 percent of the world's fish catch. The book calls upon the global community to address the illegal depletion of the world's fish stock and other similar threats to the world's food supply and natural environment in order to ensure the sustainability of the planet's fish and continuation of the legal fishing industry for generations to come.

In light of mounting fishing pressures, increased aquaculture production and a growing concern for fish well-being, improved knowledge on the swimming physiology of fish and its application to fisheries science and aquaculture is needed. This book presents recent investigations into some of the most extreme examples of swimming migrations in salmons, eels and tunas, integrating knowledge on their performance in the laboratory with that in their natural environment. For the first time, the application of swimming in aquaculture is explored by assessing the potential impacts and beneficial effects. The modified nutritional requirements of “athletic” fish are reviewed as well as the effects of exercise on muscle composition and meat quality using state-of-the-art techniques in genomics and proteomics. The last chapters introduce zebrafish as a novel exercise model and present the latest technologies for studying fish swimming and aquaculture applications.

Swimming is an integral part of the life history of many fish species as is intimately linked with their ability to express feeding and predator avoidance behaviors, habitat selection and environmental preferences, social and reproductive behaviors as well as migratory behaviors. Therefore, swimming is an important determinant factor of fitness in a true Darwinian sense and, not surprisingly, swimming performance has been often used as a measure of physiological fitness in fish. The main aim of this Research Topic is to showcase some of the current studies designed to improve our understanding of the physiological energetic and metabolic requirements of swimming and of the adaptive responses to swimming in fish.

A fish wiggles its tail to push through the water. Science explains how fish glide underwater. How Fish Swim explains how a fish's body lets it slice through the water, and the forces at work to keep them swimming along. Easy-to-read text, vivid images, and helpful back matter give readers a clear look at this subject. Features include a table of contents, infographics, a glossary, additional resources, and an index.
