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.

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

Biofouling (the colonisation of an interface by a diverse array oforganisms) is almost always a problem where it occurs, as itnegatively affects surfaces, the materials that they are made fromand the structures that they form, and can evendestroy them. This comprehensive book covers in detail in its first section theprocesses involved in marine , freshwater and medical biofoulingincluding coverage of settlement by larvae and spores, biofoulingcommunity processes, epibiosis (biofouling on livingorganisms) and microbial fouling, including biofilms deleterious tohuman health. The book's second section, encompassing biofoulingprocesses with industrial implications, includes coverage ofbiofouling on artificial substrata, paints and coatings technologyfor the control of marine biofouling, biofouling and antifouling inthe maritime industries, such as shipping, offshore oil , andaquaculture, and in power stations and other industries. Theimpacts of both biofouling and biofouling control and details ofcurrent legislation of relevance to biofouling issues are fullycovered. The book's final section looks at methods for themeasurement of biofouling, and future prospects for biofouling,including in-depth coverage of the changes anticipated inbiofouling worldwide due to global climate change, and likelyfuture directions in antifouling research, technology andlegislation. Biofouling, which includes contributions from manyinternational experts, is an essential reference for all thoseworking in the antifouling industry including those involved informulation of antifouling products such as paints and othercoatings. Aquatic biologists, ecologists, environmental scientistsand lawyers, marine engineers, aquaculture personnel, chemists, andmedical researchers will all find much of interest within thisbook. All universities and research establishments where thesesubjects are studied and taught should have copies of thisimportant work on their shelves.

This comprehensive, authoritative and up-to-date work provides the definitive overview of marine parasites worldwide. It is an invaluable reference for students and researchers in parasitology and marine biology and will also be of interest to ecologists, aquaculturists and invertebrate biologists. Initial chapters review the diversity and basic biology of the different groups of marine parasites, discussing their morphology, life cycles, infection mechanisms and effects on hosts. The ecology and importance of marine parasites are discussed in the second part of the book, where contributions investigate behavioural and ecological aspects of parasitism and discuss the evolution and zoogeography of marine parasites. In addition, the economic, environmental and medical significance of these organisms is outlined, particularly their importance in aquaculture and their effects on marine mammals and birds. Written by an international team of contributors, the emphasis is on a thorough grounding in marine parasitology combined with reviews of novel concepts and cutting-edge research.

Traditional fish stocks are in decline, yet fish products are continuously in demand, making fish culture the predominant means of supply. This dramatic expansion in fish farming has followed an intense and exciting period of research into the biology of farmed species. Biology of Farmed Fish considers the biology underlying fish culture, focusing on developments over the last decade. The chapters, written by fish biologists who have made a significant contribution to the primary research literature, are broad in nature, covering aspects of the subject with reference to a range of species from around the world. By focusing more on the biology rather than the technologies of fish farming, this book provides a unique resource for researchers, postgraduate students, and professionals interested in aquaculture.
