Using the latest research in fish nutrition, this volume revises and combines the 1981 edition on coldwater fish and the 1983 edition on warmwater fish and shellfish. In addition to updating requirements for energy, protein, minerals, and vitamins, this book provides, for the first time, summary tables on nutrient requirements of a variety of fish species, including channel catfish, rainbow trout, Pacific salmon, carp, and tilapia. Tabular data on amino acid requirements of 11 species are also included. Shellfish have been deleted from this edition due to the lack of scientific information. Index.

How much do animals eat? Why do eating patterns change? How do physiological, dietary, and environmental factors affect feed intake? This volume, a comprehensive overview of the latest animal feed intake research, answers these questions with detailed information about the feeding patterns of fishes, pigs, poultry, dairy cows, beef cattle, and sheep. Equations for calculating predicted feed intake are presented for each animal and are accompanied by charts, graphs, and tables.
The physical demands of tactical professions such as military, law enforcement, and fire and rescue require those workers to be in top physical condition to perform their jobs well and decrease the risk of injury. NSCA’s Essentials of Tactical Strength and Conditioning contains scientific information to assist in implementing or restructuring strength and conditioning programs at commercial or government fitness centers that work with these tactical athletes to achieve those goals. Designed primarily as a preparatory resource for the National Strength and Conditioning Association (NSCA) Tactical Strength and Conditioning Facilitator (TSAC-F) certification, the text is also useful as a manual for government agencies or a daily reference for strength and conditioning professionals. Editors Brent A. Alvar, Katie Sell, and Patricia A. Deuster have extensive experience as scholars and practitioners in their respective fields. They have assembled a team of distinguished contributors who bring to light current trends in strength and conditioning through their combined experiences as professionals in the fields of academia, athletic training, firefighting, law enforcement, military, nutrition, physical therapy, and strength and conditioning. The contributors not only provide foundational knowledge of exercise physiology and biomechanical movement patterns, but they also comprehensively review all of the components necessary for TSAC Facilitators to design and operate successful training programs for tactical athletes. Separate chapters focus on the specific physiological issues related to military, law enforcement, and fire and rescue personnel, including how a strength and conditioning program should directly correlate to their critical job tasks and the specific environmental, occupational, and exposure concerns for each population. Topics such as nutrition, supplements, injury treatment and rehabilitation, wellness interventions, and assessments and evaluations are discussed for professionals who work with tactical populations. Additionally, exercises, drills, and techniques targeting the specific needs of tactical athletes in areas such as flexibility, mobility, speed, agility, power, and aerobic endurance are described in great detail and accompanied by full-color photos. Each chapter of NSCA’s Essentials of Tactical Strength and Conditioning begins with learning objectives and incorporates key terms, diagrams, detailed photographs, and key points throughout the text to help guide readers and facilitate comprehension of concepts. Sidebars and sample programs are included in some chapters to help readers apply theoretical concepts in their professional practice. Additionally, for instructors using the book, or the TSAC-F exam prep symposia, a presentation package plus image bank with more than 300 photos and illustrations is available, making preparation easier with the use of predeveloped materials that correspond with the book’s content. Ultimately, the goal of NSCA’s Essentials of Tactical Strength and Conditioning is to help prepare those seeking TSAC-F certification and to serve as a resource for professionals so that they can implement an optimal strength and conditioning program targeted for tactical athletes that will decrease their risk of injury and optimize performance.
The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.
Aquaculture now supplies half of the seafood and fisheries products consumed worldwide and is gaining international significance as a source of food and income. Future demands for seafood and fisheries products can only be met by expanded aquaculture production. Such production will likely become more intensive and will depend increasingly on nutritious and efficient aquaculture feeds containing ingredients from sustainable sources. To meet this challenge, Nutrient Requirements of Fish and Shrimp provides a comprehensive summary of current knowledge about nutrient requirements of fish and shrimp and supporting nutritional science. This edition incorporates new material and significant updates to information in the 1993 edition. It also examines the practical aspects of feeding of fish and shrimp. Nutrient Requirements of Fish and Shrimp will be a key resource for everyone involved in aquaculture and for others responsible for the feeding and care of fish and shrimp. It will also aid scientists in developing new and improved approaches to satisfy the demands of the growing aquaculture industry.
Since its introduction in 1943 Recommended Dietary Allowances has become the accepted source of nutrient allowances for healthy people. These Recommended Dietary Allowances (RDAs) are used throughout the food and health fields. Additionally, RDAs serve as the basis for the U.S. Recommended Daily Allowances, the Food and Drug Administration's standards for nutrition labeling of foods. The 10th Edition includes research results and expert interpretations from years of progress in nutrition research since the previous edition and provides not only RDAs but also "Estimated Safe and Adequate Daily Dietary Intakes"â€"provisional values for nutrients where data were insufficient to set an RDA. Organized by nutrient for ready reference, the volume reviews the function of each nutrient in the human body, sources of supply, effects of deficiencies and excessive intakes, relevant study results, and more. The volume concludes with the invaluable "Summary Table of Recommended Dietary Allowances," a convenient and practical summary of the recommendations.
