Provides information about crayfish including where they live and how they reproduce.

Explores the development of the beetle, where they can be found, and their benefits to humans.

For ages 6-12. The life cycle of a wolf revolves around the complex family structure of the pack. In this book, children will learn about the intricacies of pack life and the ways in which each stage of a wolf pup's development determines its future in the family group. Photographs and illustrations of these majestic animals illuminate topics such as: different types of wolves; the preparation of a birthing den; a pup's introduction to the hunt; challenges to pack structure; dangers to wolves in the wild.

Freshwater Crayfish Aquaculture in North America, Europe, and Australia is the first text to summarize the methods of culture for the eight most important crayfish species in the world. Methods developed to culture crayfishes around the world differ significantly, and this book enables readers to develop workable strategies for cultivating different crayfish species in specific environments. Huner and associate authors cover the following topics in detail: methods of crayfish culture crayfish diseases crayfish processing economics of crayfish culture Each of the the three major crayfish industries are well-represented in this new book and special attention is given to the specific needs and accomplishments of each area, which is beneficial to producers in other countries. For example, while hatching technology has been important in Australia and Europe, it hasn?t yet been applied to any degree in North America. At the same time, North America has developed a major crayfish processing industry. Disease problems have resulted in more emphasis on that subject in Europe and yet it is vital to all involved in crayfish aquaculture. Businessmen, farmers, scientists, laymen, or students need to be exposed to the methods and problems associated with crayfish production in different parts of the world if they are to be successful in any crayfish project, whether it be research- or profit-oriented. Freshwater Crayfish Aquaculture in North America, Europe, and Australia is intended to provide all readers with one source of information on the subject of freshwater crayfish aquaculture. Professional staff, advanced students, and extension personnel will find the entire text beneficial. Those in corporate organizations and the agriculture field, especially decisionmakersin operations, will find the methods, markets, and financial considerations in this book a helpful guide.

Long ago, the Crab and the Crawfish used to be best friends. But one sweltering day, Crawfish is feeling lazy and decides to take advantage of Crab's generosity. Young readers will enjoy the colorful collage art while they learn a lesson about the consequences of tricking other people.

Written by world experts in astacology, this book covers a range of aspects of the biology and ecology of freshwater crayfish. With a strong focus on wild crayfish, the book studies the taxonomy and genetics of this interesting group of animals. Under examination also are crayfish growth and reproduction, with detailed illustrations; behavior and c

Sumerged aquatic plants limit the suitability for trout management of many shallow lakes in the Southwest. Control of these weeds has been achieved by the introduced crayfish Orconectes causeyi. The life history, ecology, and weed-control activities of the crayfish are discussed. Abundant crayfish populations occur over a wide range of elevations in permanent well-oxygenated ponds, lakes and streams where predaceous warm-water fishes are scarce. Weed control is proportional to the crayfish population and proximity of a rocky substrate which is preferred habitat. This crayfish is a tertiary burrower establishing relatively shallow burrows for hibernation and egg hatching periods. It has not damaged dams or irrigation ditches and has been compatible with local agriculture.

From the third international workshop on the subject (U. of Florence, 1997), come 18 papers reviewing the issue of alien crayfish decimating the relatively few native species in European freshwater environments. In a historical and taxonomic context, the initial paper explains why such homogenizatio

"The third edition of Ecology and Classification of North American Freshwater Invertebrates continues the tradition of in-depth coverage of the biology, ecology, phylogeny, and identification of freshwater invertebrates from the USA and Canada. This text serves as an authoritative single source for a broad coverage of the anatomy, physiology, ecology, and phylogeny of all major groups of invertebrates in inland waters of North America, north of Mexico." --Book Jacket.
