This volume provides a selection of the most significant papers presented at the Fourth Conference on Fish Telemetry in Europe, in Trondheim, Norway, in 2001. Papers are focused on migratory patterns and habitat utilisation, social behaviour, physiological ecology, fisheries management, effects of human impact on fish populations, aquaculture and methodology, and new technology.

This book is aimed at scientists and engineers actively involved in aquatic telemetry projects, aquatic biologists (marine and freshwater), fisheries biologists and managers.

The billfish is fixed at the apex of the oceanic food chain. Composed of sailfish, marlin, spearfish, and swordfish, they roam the pelagic waters of the Atlantic and are easily recognized by their long, spear-like beaks. Noted for their speed, size, and acrobatic jumps, billfish have for centuries inspired a broad spectrum of society. Even in antiquity, Aristotle, who assiduously studied the swordfish, named this gladiator of the sea xiphias--the sword.

"The Billfish Story" tells the saga of this unique group of fish and those who have formed bonds with them--relationships forged by...

A Field Guide to Coastal Fishes is a comprehensive, current, and accurate identification guide to the more than 1,000 nearshore and offshore fishes that live in brackish and marine waters from Maine to Texas.

Val Kells and Kent Carpenter bring decades of experience to this project. With Kells' detailed, vivid illustrations and Carpenter's deep knowledge of biology, taxonomy, and nomenclature, this book captures the stunning diversity of species along America's eastern shores. Key features of the book include:

- more than 1,000 full-color illustrations, set...

Sturgeons are considered living fossils, sharing many morphological and biological features with ancestral fish. Furthermore, sturgeons are of the utmost interest from an economic perspective, not only for the caviar but for the flesh. However, the wild populations of the majority of the species are at serious risk of extinction all over the world. So, it is urgent to develop strategies for both farming culture and conservation and recovery in natural habitats.

This book provides a comprehensive view of the biology and sustainable development of sturgeons putting emphasis on the...

Organotin compounds, used as antifouling biocides since 1960, are chemical compounds that act as endocrine disrupters. It is not known how organotin compounds cause hormone disturbance, however, and many questions remain about their effect on aquatic organisms. Studies on organotin compounds have recently evolved, with many new findings reported. Following a worldwide ban on organotin compounds in 2008, alternative compounds will mainly be used, with the potential for coastal areas to become contaminated, causing, among other effects, cholinesterase inhibition in aquatic organisms. Use of...
