All followers of Jesus Christ are called to become people transformed by the Holy Spirit so we can live out Gods heart for the world in terms of Christs great commission. To do that often requires Christians to move against cultural sameness, familial expectations, secular norms, religious boundaries, and even personal emotional issues. Obedience to God in todays world requires the lifestyle of a Salmon Swimmera Christian equipped to overcome whatever obstacles keep them from fulfilling Gods global agenda. Such commitment has intriguing parallels to the journey of Atlantic salmon in their effort to swim upstream to spawn the next generation of salmon.

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.

This thrilling story of the Chinook salmon beautifully illustrates nature's circle and the cycle of life. The story of the Chinook salmon is nothing less than a miracle of nature. She hatches from a tiny pearl-colored egg and begins her adventure - a 10,000-mile journey from the gravel bed of Caribou Creek to the Pacific and back. This book is part of the PAWS IV Publishing series and was originally published in 1995. Special thanks to biologists Bill Bushur, Henry Yuen, Suzi Lozo and Richard Barnes and elder Elena Charles and all the kids and parents from Newtok, Atmautlauk, Napaskiak and Kwethluk who helped me understand yaaruiq.

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.

Animals have evolved remarkable biomechanical and physiological systems that enable their rich repertoire of motion. Animal Locomotion offers a fundamental understanding of animal movement through a broad comparative and integrative approach, including basic mathematics and physics, examination of new and enduring literature, consideration of classic and cutting-edge methods, and a strong emphasis on the core concepts that consistently ground the dizzying array of animal movements. Across scales and environments, this book integrates the biomechanics of animal movement with the physiology of animal energetics and the neural control of locomotion. This second edition has been thoroughly revised, incorporating new content on non-vertebrate animal locomotor systems, studies of animal locomotion that have inspired robotic designs, and a new chapter on the use of evolutionary approaches to locomotor mechanisms and performance.

In recent years, progress in fish biology has advanced at an unprecedented rate and has led to many breakthroughs in the field. This book provides a wealth of information on the strategies that fish adopt with respect to waters with markedly different physical and chemical characteristics. It shows how their physiology, behaviour and lifestyles are adapted to exploit particular niches and gives comprehensive insight into fish life under extreme conditions. The readers are introduced to the ways in which fish exemplify many phenomena of general biological interest - the existence of competitors, chaos, and predator-prey interaction. Fish pathology as well as the components of the immune system are addressed. In this book, original and at times controversial views are presented, areas which have so far received inadequate attention are highlighted and avenues for further research are suggested.
