Taschenbuch. Zustand: Neu. Neuware - Modern aquaculture developed rapidly during the late twentieth century as global demand for seafood increased beyond what wild fisheries could sustainably provide. Among all aquaculture sectors, salmon farming emerged as one of the most technologically advanced and economically valuable industries. Atlantic salmon farming expanded aggressively across Norway, Scotland, Iceland, the Faroe Islands, Canada, and other cold-water coastal regions where environmental conditions favored high-volume marine cage production. However, as production intensified, the industry encountered one of the most destructive biological obstacles in marine aquaculture history: sea lice infestations.Sea lice are parasitic copepods that attach themselves to the skin, fins, and mucus layers of salmon. These parasites feed on host tissues, creating lesions, physiological stress, secondary infections, reduced growth rates, and in severe outbreaks, large-scale mortality. In densely stocked salmon farms, sea lice populations could reproduce rapidly because thousands of hosts were confined within relatively small marine environments. The industrialization of salmon farming therefore created ideal conditions for parasite amplification.Initially, salmon producers relied heavily on chemical treatments to control sea lice populations. Anti-parasitic compounds, bath treatments, medicated feeds, and pesticides became standard management tools throughout the industry. While these chemicals initially provided effective control, repeated usage eventually created serious problems. Sea lice began developing resistance to many treatment compounds, making chemical management increasingly ineffective and expensive. Environmental concerns also emerged because chemical discharge into surrounding marine ecosystems raised fears about ecological damage, impacts on non-target organisms, and contamination of coastal habitats.…

Neuware - Discover How to Keep Healthy, Active, and Thriving Guppies From Day OneGuppies are among the most fascinating and rewarding freshwater aquarium fish, but successful guppy keeping involves much more than simply adding colorful fish to a tank.Guppy Fish Owner's Handbook provides a practical, comprehensive guide for beginners and experienced aquarium keepers who want to understand guppy care from aquarium setup through long-term husbandry, breeding, and population management.Inside, you'll learn how to create a stable aquarium environment, choose healthy guppies, provide appropriate nutrition, recognize normal behavior, prevent common problems, and build a sustainable care routine.You'll discover how to: - Choose and set up the right aquarium for your guppies- Understand filtration, cycling, water quality, temperature, and maintenance- Select healthy guppies and introduce them safely- Establish practical feeding routines for adults, juveniles, breeding fish, and fry- Understand guppy behavior, social interactions, courtship, and stress signals- Recognize common health problems and approach symptoms responsibly- Quarantine new fish and reduce the risk of introducing disease- Identify pregnant females and prepare for live birth- Raise guppy fry through their earliest stages of development- Manage breeding colonies and prevent uncontrolled population growth- Understand basic genetics, selective breeding, color, patterns, and fin characteristics- Keep useful breeding and maintenance records- Troubleshoot problems such as poor growth, fin deterioration, abnormal swimming, aggression, cloudy water, and unstable water conditions- Develop long-term habits that support healthier fish and a more stable aquariumWhether you're preparing your first guppy aquarium, improving an established community tank, or learning how to manage a breeding program, this handbook focuses on practical decisions that can make everyday guppy care easier and more successful.Rather than treating guppies as completely maintenance-free pets, this book explains what they actually need to thrive-and how consistent observation, responsible feeding, appropriate stocking, stable water conditions, quarantine, and thoughtful breeding management work together.From your first aquarium setup to raising fry and managing future generations, Guppy Fish Owner's Handbook gives you a practical framework for becoming a more confident and responsible guppy keeper.Build the right environment. Understand your fish. Prevent problems early. Manage breeding responsibly. And enjoy the fascinating world of guppies for years to come.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - The book, entitled 'Welfare of farmed fish in present and future production systems', summarises the view of more than 80 experts in the field of fish welfare, collected over a period of more than five years in an international network entitled 'Welfare of Fish in European Aquaculture' (Cost action 867), which was sponsored by the COST Office. COST is the acronym for European Cooperation in Science and Technology. During the time of the action a shift became evident in the general perception of fish welfare. It now not only includes variables with very direct effects on growth, and thereby the economy of the farmer, such as disease, water and feed quality, but the term also includes fish preferences and biology-based stimulation measures. This Cost action has contributed to the notion that welfare sets biological criteria for a sustainable production system. We present the reader with an overview of the results obtained, which can help to guide the way towards welfare of farmed fish in present and future production systems. The first chapter gives an overview of the scientific papers that follow. All scientific papers and the first chapter were previously published in Fish Physiology and Biochemistry, vol. 38, number 1, 2012. Given the accruing interest in fish welfare in society, each of these scientific papers should be accessible for stakeholders that are not part of the research community. For that reason each of the scientific papers is preceded by a summary for non-experts. Previously published in Fish Physiology and Biochemistry, vol. 38, number 1, 2012.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book investigates how fish experience their lives, their amazing senses and abilities, and how human actions impact their quality of life. The authors examine the concept of fish welfare and the scientific knowledge behind the inclusion of fish within the moral circle, and how this knowledge can change the way we treat fish in the future. In many countries fish are already protected by animal welfare legislation in the same way as mammals, but in practice there is still a major gap between how we ethically view these groups and how we actually treat them. The poor treatment of fish represents a massive animal welfare problem in aquaculture and fisheries, both in terms of the number of animals affected and the severity of the welfare issues.Thanks to its interdisciplinary scope, this thought-provoking book appeals to professionals, academics and students in the fields of animal welfare, cognition and physiology, as well as fisheries and aquaculture management.…
