Book Description
Aquaculture, Resource Use, and the Environment places aquaculture within the larger context of global population growth, increased demand for sustainable, reliable sources of food, and the responsible use of natural resources. Aquaculture production has grown rapidly in recent decades as over-exploitation and environmental degradation have drastically reduced wild fish stocks. As fish production has increased, questions have persisted about the environmental sustainability of current aquaculture practices. Aquaculture, Resource Use, and the Environment is a timely synthesis and analysis of critical issues facing the continued growth and acceptance of aquaculture practices and products. Chapters look at the past, present, and future demands for food, aquaculture production, and tackle key issues ranging from environmental impacts of aquaculture to practical best management practices in aquaculture production. Providing broad coverage of issues that are essential to the continued development of aquaculture production, Aquaculture, Resource Use, and the Environment will be vital resource for anyone involved in the field of aquaculture.

Book Description
Abstract: Fish from Nordic fish farms have been criticized for containing "too high" concentrations of persistent organic pollutants (POPs) among others dioxin and PCB. These allegations have caused debate and may have a negative effect on the sale of products from Nordic fish farms in addition to giving a generally bad reputation that affects more or less all Nordic fish farms. It is generally agreed that the relatively high concentrations of POPs detected in fish from Nordic fish farms are caused by the high concentrations of POPs in the fish feed produced and used in the Nordic countries. Beside potential health effects caused by high POP contents in the fish fillet, the surrounding environment may be impacted as well, not only by excreted POPs but also by veterinary medicines used in the fish farms. In Nordic fish farms, veterinary medicines are mainly used therapeutically against different infectious diseases. The amount of veterinary medicines used varies from year to year and in some years, considerable amounts have been used. The major environmental concern in relation to the use of veterinary medicines is the potential occurrence of antibiotic resistance in the naturally occurring micro flora

Book Description
The aim of the book is to present for non-specialist researchers as well as for experts a comprehensive overview of the background, key ideas, basic methods, implementation details and a selection of solutions offered by a novel technology for the optimisation of the location of dangerous offshore activities in terms of environmental criteria, as developed in the course of the BalticWay project. The book consists of two parts. The first part introduces the basic principles of ocean modeling and depicts the long way from the generic principles to the practical modeling of oil spills and of the propagation of other adverse impacts. The second part focuses on the techniques for solving the inverse problem of the quantification of offshore areas with respect to their potential to serve as a source of environmental danger to vulnerable regions (such as spawning, nursing or also tourist areas). The chapters are written in a tutorial style; they are mostly self-contained and understandable for non-specialist researchers and students. They are carefully peer-reviewed by international experts. The goal was to produce a book that highlights all key steps, methods, models and data sets it is necessary to combine in order to produce a practically usable technology and/or decision support system for a particular sea region. Thus the book is useful not only as a description and a manual of this particular technology but also as a roadmap highlighting the complicated technical issues of ocean modeling for practical purposes. It describes the approaches taken by the authors in an understandable way and thus is useful for educational purposes, such as a course in industrially and environmentally relevant applications of ocean modeling. ​

Book Description
Chemicals used within the aquaculture industry are identified and for each chemical a brief summary is provided on the intended purpose, the scale of its application, the aquacultural sectors and geographic locations of its principal use and its potential impact on the environment and human health. Environmental issues arising from the properties of aquacultural chemicals are discussed. The use of most chemicals in aquaculture, if carried out properly, can be regarded as wholly beneficial with no attendant adverse environmental effects or increased risks to the health of aquacultural workers. Concerns appear warranted, however, regarding the overuse and misuse of certain chemicals for which proper risk assessments with respect to the marine environment have not been conducted. A further legitimate concern and a barrier to the conduct of an exhaustive review of chemical use practices is the unavailability of quantitative data on contemporary chemical use in the aquaculture industry. The viability of contemporary aquaculture is contingent on the use of chemicals. Accordingly, with the overriding consideration should be minimizing the quantities of chemicals applied, most current uses of chemicals are essential. This study, recognizing that chemotherapeutants and pesticides in current use are of verying effectiveness and hazard, provides recommendations to promote the safe and effective use of chemicals in coastal aquaculture. Government authorities, the scientific community and the aquacultural and pharmaceutical industries all have an important to play in ensuring that chemical use is consistent with protection of environmental quality and human health.

Book Description
Chemicals used within the aquaculture industry are identified and, for each chemical, a brief summary of information is provided, when available, on its intended purpose, scale of application, the aquacultural sectors and geographic locations of principal use and potential impacts on the environment and human health. Environmental issues arising from the properties of aquacultural chemicals are discussed. The use of most chemicals in aquaculture, if carried out properly, can be regarded as wholly beneficial with no attendant adverse environmental effects or increased risks to the health of aquacultural workers. Concerns appear warranted, however, regarding the over-use and misuse of certain chemicals for which proper risk assessments with respect to the marine environment have not been conducted. A further legitimate concern and a barrier to conducting an exhaustive review of these practices is the lack of availability of quantitative data on contemporary chemical use in the aquaculture industry. The viability of contemporary aquaculture is contingent on the use of chemicals. Accordingly, while the overriding consideration should be minimizing the quantities of chemicals applied, most current uses of chemicals are essential. Recognising that chemotherapeutants and pesticides in current use are of varying effectiveness and hazard, recommendations are provided to promote the safe and effective use of chemicals in coastal aquaculture. Governmental authorities, the scientific community and the aquacultural and pharmaceutical industries all have important roles to play to ensure that chemical use is consistent with protection of environmental quality and human health. In particular, mechanisms need to be put in place and enforced for the registration and control of aquacultural chemicals to protect the environment and human health and to ensure the sustainable growth of the aquaculture industry.
