Towards a sustainable fishery and use of cleaner fish in salmonid aquaculture: Challenges and oportunities
Available online: https://pub.norden.org/temanord2021-545/ Salmon lice cause economic losses in salmonid aquaculture. The use of cleaner fish has become an important tool to fight lice. Lumpfish and several species of wrasses are used. There are extensive fisheries for wrasses, and aquaculture of ballan wrasse and lumpfish. Fisheries and use have evolved fast, but the development of a regulatory framework has lagged behind. Challenges linked to poor welfare, diseases and changes in the genetic structure have raised questions on the sustainability of the current practice, and The Norwegian Food Safety Authorities stated that if the welfare is not improved and the effect of cleaner fish better documented, the use can be reduced or terminated. This will have implications for the Swedish and potential future Danish fishery. This report presents the state-of-knowledge on biology, fisheries and how management have dealt with the fisheries and use.
Oceanic Anglerfishes
No environment on Earth imposes greater physical and biological constraints on life than the deep oceanic midwaters. Near-freezing temperatures, the absence of sunlight, enormous pressure, and a low food supply make habitation by any living thing almost inconceivable. Yet 160 species of anglerfishes are found there in surprising profusion. Monstrous in appearance, anglerfishes possess a host of unique and spectacular morphological, behavioral, and physiological innovations. In this fully illustrated book, the first to focus on these intriguing fish, Theodore W. Pietsch delivers a comprehensive summary of all that is known about anglerfishes—morphology, diversity, evolution, geographic distribution, bioluminescence, and reproduction.
The Physiology of Polar Fishes
Devoted to fishes of high latitudes (Arctic and Antarctic). This book includes themes such as: the uniqueness of the physiology of fishes that live in cold polar environments, an analysis of physiological patterns exemplified by fishes that live poles apart, and how fishes differ from fishes living in more temperate and tropical habitats.
The Ecology of Marine Fishes
“A masterful accomplishment—Allen, Pondella and Horn have assembled a talented team of experts who produce authoritative, up-to-date accounts. This book will be used as the primary text in many fish biology courses and as a valuable reference elsewhere. Here is a wealth of data waiting to be mined by legions of graduate students as they generate the new ideas that will motivate marine ecology for years.”—Peter Sale, Editor of Coral Reef Fishes: Dynamics and Diversity in a Complex Ecosystem "A copiously illustrated and comprehensive interpretation of the past, present, and future state of over 500 species of fishes in Californian waters. A compilation of virtually all the many important studies on the ecology of California marine fishes."—Bruce B. Collette, National Marine Fisheries Service and co-author of The Diversity of Fishes

Marine Fishes of Arctic Canada
Marine Fishes of Arctic Canada is an accessible and up-to-date study on the diverse marine fish population existing in Canadian waters.
Biology and Ecology of Bioluminescent Marine Fishes
This enlightening new volume details over 200 species of bioluminescent marine fishes along with their biotechnological and therapeutic applications. It delves into the chemistry, diversity, biology, and functions of these fishes. Bioluminescence, which is a type of chemiluminescence and is a "cold living light," is seen in a wide variety of organisms from bacteria to fish. The chemicals and circumstances of this phenomenon are used for biotechnological, commercial, and therapeutic applications. Bioluminescence imaging technology has provided valuable means for the monitoring of different biological processes for immunology, oncology, virology, and neuroscience. A new emerging biological tec...
Brown Trout
Brown Trout: Biology, Ecology and Management A comprehensive guide to the most current research, history, genetics and ecology of the brown trout including challenging environmental problems The brown trout is an iconic species across its natural European distribution and has been introduced throughout the World. Brown Trout offers a comprehensive review of the scientific information and current research on this major fish species. While the brown trout is the most sought species by anglers, its introduction to various waters around the world is causing serious environmental problems. At the same time, introduction of exogenous brown trout lineages threats conservation of native gene pools o...
My Work
From the acclaimed author of The Employees, a radical, funny, and mercilessly honest novel about motherhood. After giving birth, Anna is utterly lost. She and her family move to the unfamiliar, snowy city of Stockholm. Anxiety threatens to completely engulf Anna, who obsessively devours online news and compulsively orders clothes she can’t afford. To avoid sinking deeper into her depression, she forces herself to read and write. My Work is a novel about the unique and fundamental experience of giving birth, mixing different literary forms—fiction, essay, poetry, memoir, and letters—to explore the relationship between motherhood, work, individuality, and literature.“Olga Ravn writes dazzlingly about the work of motherhood and the work of writing. Reading Ravn’s book, you run through the whole gamut of human emotion, as though you too were a new mother: tears, laughter, anger, fear, pain, frustration. This is powerful writing that’s hard to put down.”—Politiken
