Carp and Catfish [PDF ebook] 
Biology, Behavior and Conservation Strategies

In general, aquaculture and fish farming cause negative impacts on the environment and wild fish populations. One of the major problems is the escape of farmed fish, especially exotic species, which can alter the population dynamics and ecology of wild stocks. Therefore, the reduction or even extinction of natural stocks may occur through predation and/or competition for resources. This book discusses the biology, behavior and conservation strategies of both carp and catfish.
