Sea lice remain one of the main problems in salmon farming, with estimated costs of treatment and losses of fish running to several million pounds each year in Scotland alone. The use of chemical methods by the industry has brought adverse publicity and wrasse (cleaner fish) present an alternative, environmentally friendly means of biological control. As a result, the demand for wrasse has spawned a new inshore fishery, and this has led to calls for more information on the population dynamics and size of stocks. Attempts are also being made to rear wrasse for stocking. As a consequence there is considerable interest in cleaner fish technology from fish farmers and research workers. This book draws together the latest information on the biology and culture of wrasse, and the use of wrasse in controlling sea lice.
Cleaner fish are increasingly being deployed in aquaculture as a means of biological control of parasitic sea lice, and, consequently, the farming of wrasse and lumpfish, the main cleaner fish species in current use in salmon farming, is now one of the fastest expanding aquaculture sectors with over 40 hatcheries in Norway alone. Cleaner Fish Biology and Aquaculture Applications reviews and presents new knowledge on the biology of the utilised cleaner fish species, and provides protocols in cleaner fish rearing, deployment, health, and welfare. The latest knowledge is presented on specialist technical areas, such as: cleaner fish nutrition; genetics; health; immunology and vaccinology; welfare; transport; and fisheries. Specific chapters detail cleaner fish developments in the main salmon-producing countries. Contributions from over 60 leading researchers and producers give an exciting mix of information and debate. The book comprehensively addresses the questions of sustainability of cleaner fish use in aquaculture, bottlenecks to the optimum production of cleaner fish, and improvements and best practice in on-farm deployment methods, for optimum survival and enhanced welfare of cleaner fish. Some of the key features of this important book includes: a comprehensive review of the latest globally-available information on the use of cleaner fish; discussion of the main issues in the farming of cleaner fish; guidance on how to improve growth and survival; and details on how to address issues in the farm application of cleaner fish. Written by a team of internationally-recognised experts in cleaner fish biology, culture, and deployment this book will be an essential purchase for hatchery managers, salmonid producers, fish farm operatives, researchers, regulators, students, and enthusiasts working with, and interested in, cleaner fish.

This landmark volume considers the biology underlying fish culture, focusing on developments over the last decade. The approach is ordered according to life-stage or discipline, rather than according to species. The chapters, written by biologists who have made outstanding contributions to the international research literature, draw on examples from a range of species around the world.
There are currently 3-5 million cases of leishmaniasis in the world and the prevalence is rising. The first chapter in this volume reviews the cell biology of the parasite and its transmission and survival. The second review addresses the apicomplexan protozoan parasites Theileria anulaga, T. parva and T. sergenti which globally cost agriculture over one billion US dollars annually. Current research in this area aims to produce effective, stable and cheap subunit viruses requiring only a single application and the authors predict that success will eventually be achieved with 'naked DNA' vaccines containing cytokine genes as immunopotentiators. The next review is the first in over 30 years to discuss the larva of the class Monogenea.The authors cover morphology, behaviour and structure of many examples providing a detailed reference for researchers. The penultimate chapter discusses the distribution of Schistosoma bovis and considers the reported interactions occurring between parasites and snails. The final chapter reviews one of the most serious parasitic diseases in salmonid aquaculture - sealice. In 1998 the costs due to sealice damage in Scotland alone were estimated at 15-30 million pounds. Discussion of biology and control of these ectoparasites emphasizes the need to understand the basic biology of the parasite. This volume will be essential reading for parasitologists in many branches of the subject.
With wild stocks declining due to over-fishing, aquaculture will have a more significant role to play in meeting future demand for fresh fish. Developments in research continue to lead to improvements in aquaculture production systems, resulting in increased production efficiency, higher product quality for consumers and a more sustainable industry. New technologies in aquaculture reviews essential advances in these areas. Part one focuses on the genetic improvement of farmed species and control of reproduction, with chapters on genome-based technologies in aquaculture research, selective breeding and the production of single sex and sterile populations, among other topics. Parts two and three review key issues in health, diet and husbandry, such as the control of viral and parasitic diseases, diet and husbandry techniques to improve disease resistance, advances in diets for particular fish species and the impact of harmful algal bloom on shellfisheries aquaculture. Chapters in Parts three and four then examine the design of different aquaculture production systems, including offshore technologies, tank-based recirculating systems and ponds, and key environmental issues, such as the prediction and assessment of the impact of aquaculture. Concluding chapters focus on farming new species. With its well-known editors and distinguished international team of contributors, New technologies in aquaculture is an essential purchase for professionals and researchers in the aquaculture industry. Reviews recent advances in improvements in aquaculture production Focuses on the genetic improvement and reproduction of farmed species, including genome-based technologies Discusses key health issues, including advances in disease diagnosis, vaccine development and other emerging methods to control pathogens in aquaculture

Over the past few years, it has become more and more obvious that fish farming will become increasingly important in the future. As fish farming moves into its industrial phase, technology will be an important factor in determining its successful development. It is therefore important for scientists & representatives from the aquaculture industry to meet to define state of the art and explore future development of fish farming technology for different fish species. 81 papers and abstracts were presented at the conference. The proceedings reflect the different sections of the conference: the plenum sessions and three parallel sessions: Juvenile marine fish, open production plants, closed production plants and poster sessions.
Sea lice are serious pests of commercially farmed fish and this book provides the first detailed overview of their biology and existing methods of control. It deals comprehensively with both the pure and applied aspects of sea lice biology and covers a wide range of topics to make it invaluable to practitioners and researchers alike.
