This book was released on 2009 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing frequencies of cataracts (i.e., opacities in eye lens) have been diagnosed in farmed salmonids during past years. Cataracts have proven a pronounced problem in fish farming because it leads to reduced eyesight and even total blindness of the fish. Norway has been leading research on cataracts because of the economic significance of Atlantic salmon farming. Other issues in respect of stocking and animal welfare have been considered. There are still knowledge gaps on the causes of cataract as well as on its consequences. Furthermore, quantitative information on the severity of the problem is still largely lacking. The report presents results from a number of case studies that have been conducted by the project group and collaborators. The project has shown cataracts to be relatively common in all the six salmonid species included in surveys from Finland and Sweden. The prevalence and severity (coverage of eye lens) were however variable often related to an exposure to Diplostomum spp. parasites that use fish as their intermediate hosts. The result contrasts with findings from Norway about the importance of nutritional imbalance and environmental (abiotic) factors in predisposing fish to cataract development.

For the 22nd edition much new and updated information has been included, reflecting the numerous developments that have taken place in animal care and husbandry, and welfare. There is greatly expanded coverage of topics relating to popular breeds of dog and cat, and the inheritable conditions that might affect their health. Advances in medicine, surgery and diagnostic techniques; descriptions of newly identified diseases such as Schmallenberg virus; the resurgence of old scourges such as TB in cattle, and ongoing enzootic infections such as bird flu are included in this new edition. The growing risk of exotic diseases such as heartworm being imported following the relaxation of travel arrangements for dogs and cats is reflected in new entries. Notes on many new species being farmed or kept as companion animals are among the thousands of topics covered. Whether your interest is in cats or cattle, horses or hamsters, puppies or pigeons, the A-Z of veterinary matters is covered in Black's Veterinary Dictionary.
Book Synopsis Towards a sustainable fishery and use of cleaner fish in salmonid aquaculture: Challenges and oportunities by : Tallaksen Halvorsen, Kim
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.
Book Synopsis Fish Parasites by : Patrick T. K. Woo
Download or read book Fish Parasites written by Patrick T. K. Woo and published by CABI. This book was released on 2012 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: Focusing on pathobiology and protective strategies against protozoan and metazoan parasites of fish, this book reviews the latest research on important parasites: those that cause financial hardships to the aquaculture industry, have been introduced to new geographical regions through transportation of infected fish, are pathogenic to groups of finfish and detrimental to production, are highly adaptable and not host-specific with worldwide distributions, and that may serve as disease models for studies on other pathogens. It also highlights gaps in the knowledge to help direct future research.

Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive and authoritative synthesis on the successful production of fish larvae Success Factors for Fish Larval Production is a vital resource that includes the most current understanding of larval biology, in the context of larval production. The text covers topics such as how external (environmental and nutritional) and internal (molecular/ developmental/ physiological/ behavioral/ genetic) factors interact in defining the phenotype and quality of fish larvae and juveniles. The expert contributors review broodstock genetics and husbandry, water quality, larval nutrition and feeding, growth physiology, health, metamorphosis, underlying molecular mechanisms, including epigenetics, for development, larval behavior and environmental conditions. Compiled by members of a European Union-funded consortium of top researchers, Success Factors for Fish Larval Production provides a wide-range of authoritative information for the aquaculture industry and academia. In addition to a wealth of information, the authors review research and commercially applicable larval quality indicators and predictors. The successful production of good-quality fish larvae is of vital importance for fish farming and stock enhancement of wild fisheries: Includes contributions from a consortium of noted researchers and experts in the field Deals with on how to improve egg quality and larval production via broodstock management and nutrition Suggests ways to control the phenotype of juveniles and table-size fish via manipulations of the conditions of larval rearing (e.g., epigenetics) Includes ideas for optimizing diet composition, formulation, and technology Integrates knowledge and practical experience in order to help advancing excellence in aquaculture Success Factors for Fish Larval Production offers fish biologists, developmental biologists, physiologists and zoologists the most current and reliable information on the topic.

Book Synopsis Policy recommendations and smallholder guidelines in improved fish smoking systems by : Food and Agriculture Organization of the United Nations
Download or read book Policy recommendations and smallholder guidelines in improved fish smoking systems written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-07-17 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smoked fish is an important animal protein source in Ghana. However, the traditional method by which the commodity is produced leads to high levels of polycyclic aromatic hydrocarbons (PAH, a food safety hazard) in the commodity. This predisposes consumers to potential health challenges linked to PAH exposure in food. The extent to which that is the case in Ghana was evaluated by screening smoked fish on informal markets in the country for the hazard. Since the FAO-Thiaroye fish processing technique (FTT) has been demonstrated to address the PAH problem, it was further evaluated against traditional kilns in that respect. Consumer acceptance of smoked products from the FTT versus the traditional kilns was also evaluated. The findings demonstrated the high PAH levels associated with traditional kilns, and the efficacy of the FTT in that regard. Consequently, a risk assessment showed that should FTT be used instead of traditional kilns to smoke fish in the Ghana, consumers will be protected from PAH public health risks related to smoked fish consumption. It was also found that overall, consumers are likely to accept products from the new kiln since they did not show a significant preference for traditional kiln products.
