Host Defence Reactions of the Shore Crab, Carcinus Maenas (L.), in Vitro

The Crustacea play an important economic role in the marine and aquatic environments not only as a food source but also in the productivity of the fisheries. Exploitation of these resources has led to a need for intensive culture methods which impose physiological stress on the animals and consequently increase the incidence of disease. The need to reduce the lethal and debilitating effects of pathogens has stimulated a renewed interest in the defence mechanisms of the Crustacea.
