Techniques d'élevage en masse d'un Rotifère (Brachionus plicatilis Müller) et d'un Crustacé Branchiopode (Artemia salina L.)

This work deals with the influence of the diet (qualitative and quantitative aspect) on the daily production of a population of Brachionus plicatilis and on the growth an survival of the brine shrimp Artemia salina. It was tried to reduce the manipulation to a minimum and to use the available volume most adequately. For B. plicatilis the best results were obtained with fresh Tetraselmis suecica as food. Nevertheless it is possible to maintain the population at a satisfactory level of production with preserved food. For A. salina the use of algae powder gave the best growth and survival. It is demonstrated that it is worth using low cost, easy to store dried food, which permits mechanical feeding. [NOT CONTROLLED OCR]
