Fisheries Acoustics
Living resources of the sea and fresh water have long been an important source of food and economic activity. With fish stocks continuing to be over-exploited, there is a clear focus on fisheries management, to which acoustic methods can and do make an important contribution. The second edition of this widely used book covers the many technological developments which have occurred since the first edition; highly sophisticated sonar and computer processing equipment offer great new opportunities and Fisheries Acoustic, 2e provides the reader with a better understanding of how to interpret acoustic observations and put them to practical use. Well known and respected authors Emphasis on practical acoustic methods Detailed coverage of a commercially and environmentally important subject A vital tool for fisheries scientists, fisheries oceanographers, environmental biologists, ecologists, population biologists, fish biologists, and marine biologists. All those involved with design and use of acoustic equipment. Libraries in research establishments, government stations and universities where fisheries science is studied or taught will find this a welcome addition to their shelves.
Cultural Mapping as Cultural Inquiry
This edited collection provides an introduction to the emerging interdisciplinary field of cultural mapping, offering a range of perspectives that are international in scope. Cultural mapping is a mode of inquiry and a methodological tool in urban planning, cultural sustainability, and community development that makes visible the ways local stories, practices, relationships, memories, and rituals constitute places as meaningful locations. The chapters address themes, processes, approaches, and research methodologies drawn from examples in Australia, Canada, Estonia, the United Kingdom, Egypt, Italy, Malaysia, Malta, Palestine, Portugal, Singapore, Sweden, Syria, the United Arab Emirates, the...

Fish Swimming
Among the fishes, a remarkably wide range of biological adaptations to diverse habitats has evolved. As well as living in the conventional habitats of lakes, ponds, rivers, rock pools and the open sea, fish have solved the problems of life in deserts, in the deep sea, in the cold antarctic, and in warm waters of high alkalinity or of low oxygen. Along with these adaptations, we find the most impressive specializations of morphology, physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins, sailfish and warm-blooded tunas, air-breathing in catfish and lung fish, parental care in the mouth-brooding cichlids and viviparity in many sharks and toothcarps.
