The Feasibility of Electrotaxis and Phototaxis in American Crayfish

American crayfish Procambarus clarkii (Girard 1852) has been supporting in one way the aquaculture industry with remarkable commercial success in USA and other countries because of its rapid growth and ecological tolerance. The other side many countries have been regulating the introduction of this invasive species due to their adverse impacts on the native species and the ecosystems including interference with fishing operations and consumption of eggs of other fishes. In order to remove this exotic species an effective low-cost harvesting method is needed. This book therefore provides new ideas and synthesizes novel concepts which improved experimental designs in ascertaining the feasibility of either electrotaxis or phototaxis of American crayfish. The detailed behavioral responses and possible applications of the novel luring method are further discussed. This would be especially useful to the farmers and/or professionals in addressing the essential requirements for commercializing the culture or developing environmental control measures of the species.
