Odeh (Conte Anadromous Fish Research Center) presents 13 contributions which explore the technical possibilities of constructing effective fish bypass systems for hydroelectric dams, especially those that are due for relicensing in the context of new regulations. The articles consist of case studies in the effectiveness of such techniques as surface bypass systems, modular inclined screens, hydroacoustic evaluation of fish entrainment patterns, surface collection, surface spill gates, and radio-tagging and radar tracking behavior evaluation strategies.

The high market demand based on consumers’ trust in fish as a healthy and nutritious food resource made fish processing a very dynamic industry, spurring many innovations in processing and packaging methods. Trends in Fish Processing Technologies not only reflects what is currently new in fish processing but also points out where things are heading in this area. This book provides an overview of the modern technologies employed by the industry. It details the advances in fish processing, including high pressure processing (HPP), pulsed electric field (PEF) treatment and minimally heat processing combined with microwave (MW) and radio-frequency (RF). It provides references to food safety management systems and food safety & quality indicators for processed fish in order to achieve an adequate level of protection. Quality aspects and molecular methods for the assessment of fish and fish products integrity are introduced. Fish products reformulation trends based on sustainability principles that tackles the reduction of salt content and the use of natural antimicrobials are presented. Innovative packaging solutions for fish products are explored, detailing intelligent packaging with freshness and time-temperature indicators, applications of modified packaging atmosphere, antimicrobial bio-nanocomposite packaging materials and biodegradable edible films used as primary fish packaging. In addition to covering the current advancements in fish processing the book discusses fraud, adulteration, fair trade practices, traceability and the need for added value, clean and sustainable processing in the fish chain.
As with the first edition this book includes chapters on established fish processes and new processes and allied issues. The first five chapters cover fish biochemistry affecting processing, curing, surimi and fish mince, chilling and freezing and canning. These established processes can still show innovations and improved theory although their mature status precludes major leaps in knowledge and technology. The four chapters concerned with new areas relevant to fish processing are directed at the increasing globalisation of the fish processing industry and the demands, from legislation and the consumer, for better quality, safer products. One chapter reviews the methods available to identify fish species in raw and processed products. The increased demand for fish products and the reduced catch of commercially-important species has lead to adulteration or substitu tion of these species with cheaper species. The ability to detect these practices has been based on some elegant analytical techniques in electrophoresis.
