The design and development of a life supporting system for experimenting on salmonids

Abstract This study concerns the development and the testing of a system which permits intensive rearing of aquatic animals. The system offers practical opportunities for various experimental situations, sufficient carrying capacity to allow statistical analysis, ease of operation, and insures the stability necessary for experimental interpretation. It has the advantages of being constructed at a low cost and of offering great flexibility. Experiments have been conducted for testing the system with the brook trout Salvelinus fontinalis , which have demonstrated its reliability. It is shown that structural and functional characteristics of this culturing system permit the underlining of aspects of growth and health which are difficult to analyze in similar studies.
