Abstract The object of the proposed research is to understand the digestive physiology and the nutritional requirements of Sea Bream (Sparus aurata) larvae, in order to limit the high mortality observed at the start of the exotrophic stage, to increase their growth rate and to help avoid certain developmental anomalies such as osseous teratogenesis. Having obtained some experimental results we now propose to raise these larvae with various controlled diets, consisting of phytoplancton (monoalgal chlorella cultures) or food solutes in sea water (mainly carbohydrates). We also propose to control both the quantitative aspects and the frequency/rhythm of the administration of these diets. A study of survival and growth rates will accompany the analysis of functional anomalies and pathological states brought about by qualitative nutrient insufficiencies and/or of nutrient administration regimes (quantity, frequency). The study of the functional morphology of the digestive system will consist of an examination of the anterior intestine (lipid absorption), the posterior intestine (protein absorption), the pancreas (enzyme secretion) and the liver (lipid and glycogen dynamics, biliary secretion).
