The influence of gutting on the quality of fish is discussed. The conclusion of this study is that the usefulness of evisceration depends upon many factors: duration of the voyage, fish species, size and quality of the catch season (influence of temperature), etc.In most cases however, gutting is to be recommended. As it is a very laborious operation especially when important quantities of fish are caught and as it should be carried out carefully in order to keep the quality of the fish at a high level, gutting machines represent a real progress, allowing better working conditions. In recent years, several interesting machines were proposed abroad. A brief description of the most important types is given in this article
