While there has been increasing interest in recent years in the welfare of farm animals, fish are frequently thought to be different. In many people’s perception, fish, with their lack of facial expressions or recognisable communication, are not seen to count when it comes to welfare. Angling is a major sport, and fishing a big industry. Millions of fish are caught on barbed hooks, or left to die by suffocation on the decks of fishing boats. Here, biologist Victoria Braithwaite explores the question of fish pain and fish suffering, explaining what we now understand about fish behaviour, and examining the related ethical questions about how we should treat these animals.
Scots like to smoke or salt them. The Dutch love them raw. Swedes look on with relish as they open bulging, foul-smelling cans to find them curdling within. Jamaicans prefer them with a dash of chili pepper. Germans and the English enjoy their taste best when accompanied by pickle’s bite and brine.The herring has done much to shape both human taste and history. Men cooperated and came into conflict over its shoals, setting out on boats to catch them and straying to bring full nets to shore. Women gutted and salted the catch during the annual harvest and knitted the garments fishermen wore to protect them from the ocean’s chill.F
Spiny lobsters are among the world′s most valuable and highly prized seafoods, captured and marketed in over 90 countries. Demand for spiny lobsters has escalated in the past two decades, spurring the need both for better management and for research on which to base that management.
Some 300 species of amphibians inhabit North America. The past two decades have seen an enormous growth in interest about amphibians and an increased intensity of scientific research into their fascinating biology and continent-wide distribution.This atlas presents the spectacular diversity of North American amphibians in a geographic context. It covers all formally recognized amphibian species found in the United States and Canada, many of which are endangered or threatened with extinction. Illustrated with maps and photos, the species accounts provide current information about distribution, habitat, and conservation.R
In the sixteen years since the last edition of Von Brant s classic work was published, fishing and fisheries have undergone vast changes. Not only has there been great progress in the development of new tools, materials and techniques, but the industry has seen an increasing need to address controversial issues such as declining fish stocks, enormous quantities of bycatch and discard and the impact of towed fishing gear on the environment.
Frogs from the genus Xenopus have long been used as model organisms in basic and biomedical research. These frogs have helped unlock key fundamental developmental and cellular processes that have led to important scientific breakthroughs and have had practical application in embryology, cancer research and regenerative medicine. Xenopus Development is a vital resource on the biology and development of these key model organisms, and will be a great tool to researchers using these frogs in various disciplines of biological science.
Throughout much of the world, frog populations are declining and some species are disappearing totally. In Australia, several species have become extinct in the past 25 years.This revised and updated guide provides concise accounts of all the known frogs of Australia. There are 230 species within the five native frog families: Hylidae, Limnodynastidae, Microhylidae, Myobatrachidae and Ranidae. Also included are the introduced Cane Toad and nine stowaway species that have arrived in Australia.The text for each species includes details of size, status, distribution, habitat, behavior and advertisement call.
One fish, two fish, red fish, nearly thirty thousand species of fish―or fishes, as they are properly called when speaking of multiple species. This is but one of many things the authors of this fascinatingly informative book reveal in answering common and not-so-common questions about this ubiquitous group of animals.Fishes range in size from tiny gobies to the massive Ocean Sunfish, which weighs thousands of pounds. They live in just about every body of water on the planet. Ichthyologists Gene Helfman and Bruce Collette provide accurate, entertaining, and sometimes surprising answers to over 100 questions about these water dwellers, such as "How many kinds of fishes are there?" "Can fishes breathe air?" "How smart are fishes?" and "Do fishes feel pain?" They explain how bony fishes evolved, the relationship between them and sharks, and why there is so much color variation among species.
