This book synthesizes existing knowledge of the process of domestication and how captive
breeding and management of wild and domestic animals have affected their behaviour and …

Why do captive‐reared fishes generally have lower fitness in natural environments than wild
conspecifics, even when the hatchery fishes are derived from wild parents from the local …

The world's fish species are under threat from habitat degradation and over‐exploitation. In
many instances, attempts to bolster stocks have been made by rearing fish in hatcheries and …

Competition between hatchery-reared and wild salmonids in streams has frequently been
described as an important negative ecological interaction, but differences in behavior …

Summary 1 Although it is not clear to what extent density dependence acts on the survival,
emigration or growth of organisms, experiments testing alternative explanations are rare. A …

State and federal agencies in the United States annually release millions of hatchery salmon
and steelhead into public waters. Many of the hatchery programs are located in areas where …

Summary 1 Interactions between captive‐reared and wild salmonids are frequent because
hatcheries annually rear millions of fish for release in conservation programmes while many …

It is our goal in this text to use evolutionary principles as a unifying theme for exposing
students to a number of approaches to the field of animal behavior and to demonstrate that …

Hatcheries often produce bold fish that are maladapted to survive in the wild, as absence of
predators and selection for fast growth tend to favour risk-taking behaviors. Not surprisingly …

Hatchery-reared aquatic animals tend to perform worse in natural environments than wild
conspecifics. This was pointed out over a century ago and while there are many possible …
