The fresh water Clam (Anodontites trapesialis), is a typical species of the forest, reproducing in form accelerated in all the lagoons or mirrors of water dedicated to the culture and investigation of other species, introducing itself in the form of larva soon to follow its development until arriving at its state of adult. The development is uncontrollable, reasOn why the unique form to control the presence of these clams is realising its advantage by means of industrialization, which will allow to generate added value, to create new power supplies and sources of work. In this project of lnvestigation one looked for to determine technological parameters as far as the selection of the clams considering parameters like: weight, charts, you enter other characteristics of such form to obtain majors pulp yields or meat with respect to the gross weight, also determinad the most suitable parame...
