Download or read book Towards a sustainable fishery and use of cleaner fish in salmonid aquaculture Challenges and oportunities written by Tallaksen Halvorsen, Kim and published by Nordic Council of Ministers. This book was released on 2021-12-03 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Sea Lice Biology and Control written by Jim Treasurer and published by 5m Books Ltd. This book was released on 2022-10-31 with total page 857 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea lice are one of the most important and costly health issues for Atlantic salmon aquaculture and for culture of many other marine fish species. In addition, the extent and causes of impacts of sea lice upon wild salmonids has proven a hotly debated issue and one that continues to affect public perceptions of aquaculture. It is 29 years since the last dedicated book on sea lice biology and management, Pathogens of Wild and Farmed Fish: Sea Lice (Boxshall and Defaye, 1993), and a volume of current perspectives is overdue. The current book updates knowledge concerning the biology and management of sea lice, authored by over 60 world-leading researchers, practitioners and industry experts, written in an accessible and engaging style. New topics include genomics, vaccinology, physiology and epidemiology, and aspects of interactions with wild fisheries are thoroughly reviewed. Sea Lice Biology and Control is of interest to and provides an invaluable reference for sea lice researchers, parasitologists, students, fish farmers, veterinarians and other fish health professionals, wild fish biologists and managers, regulators, government, fish certification professionals and NGOs. The book provides an authoritative overview of sea lice and their interactions and gives a clear illustration of the application of the principles of integrated pest management in an aquaculture context. 5m Books

Download or read book Ongoing Research in Jawed Fish Immunity Structural and Functional Studies at the Protein and Cellular Levels written by Monica Imarai and published by Frontiers Media SA. This book was released on 2020-06-04 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of jawed fish immune systems obtained in the last 15 years has been mostly obtained through the sequencing of genomes of different fish species and from the use of high-throughput techniques such as transcriptomic analysis and RNA sequencing, which has allowed characterization of immune gene responses at the transcriptomic level. Although these have been important tools for exploring the complexities of the immune responses of fish species, the next generation of knowledge requires the use of new tools and methods capable of unveiling the diversity of immune cells and molecules in jawed fish, the network of interactions and responses, and the mechanisms leading to immune protection against pathogens. For more than 10 years, many laboratories have been engaged in developing antibodies against key molecules of jawed fish immune systems in several different species because the lack of sequence conservation of most immune genes makes it impossible to use the large panel of antibodies against mammalian molecules for recognition of fish molecules. The numerous genes encoding cytokines and receptors have now been used to make recombinant proteins available, allowing studies of the complex network of cytokine and receptor functions central to fish immune responses. From many laboratories, new and interesting knowledge about immune cells, their functions and interactions can be studied with the availability of new tools and methods have begun to provide a clear understanding fish immunity at the protein and cellular levels. This Research Topic gives a comprehensive overview of the current knowledge of jawed fish immune responses with a particular emphasis on structural and functional studies at the protein and cellular levels.
Download or read book Rocky Shores written by John Archer-Thomson and published by Bloomsbury Publishing. This book was released on 2019-02-21 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rocky Shores explores the species, communities and landscape of the narrow strip of land along our coastline. Limited in extent it may be, but no other habitat in Britain is as extreme and dynamic. As the tide ebbs and flows, physical and chemical conditions can alter dramatically in a matter of minutes, yet an impressive number of life forms have adapted and even thrive in these challenging conditions. Rock pools dotted across the shore contain unique pockets of diversity, while the strandline at the high-tide mark supports a curious community of microbes and invertebrates that in turn attract birds and mammals. John Archer-Thomson and Julian Cremona gently guide the reader through the patterns of marine biodiversity that might be encountered on sheltered and exposed shores: from the inhospitable 'splash zone' to the repeatedly submerged lower shore, and everything in between. In addition to the ecology, there is also much to be said about our cultural and historical links with the shore, and the authors also reflect on what the future may hold for this beautiful but vulnerable coastal ecosystem. Filled with stunning photographs of rocky shores and their extraordinary inhabitants, this book will appeal to anyone with a love of the shore – from the occasional 'rockpooler' through to enthusiastic naturalist.
