APPLICATION OF MICROCALORIMETRY FOR ARTEMIA ENERGY CONTENT EVALUATION

摘要

Artemia is used in aquaculture as a live start prey in any of its ontogenic stages, but the new hatched nauplia are the most preferable food for crustacean and fish larvae. It's connected with the small size and higher energy contents (Navarro et al.,1991). At the same time it's well known that the different Artemia strains contain different energetic value which is very important to know for their commercial availability. Energetic content of aquatic animals are determined by various analytical techniques, including biochemical and physiological analysis. Direct calorimetry is preferable in this case because it permits to study metabolic rate of the animals in vivo and the changes of its dynamics during development. Thus the goal of the present study was to determine the metabolic rate of two geographical Artemia strains in various developmental stages by microcalorimetry method.
