Abstract

1. 1. Postprandial effects on serum lipoprotein distribution were determined in juvenile steelhead trout (Salmo gairdnerii). 2. 2. As many as eight lipoproteins were detected, including proteins of α, α2, and β mobility, as well as up to three discrete proteins with albumin-like mobility. 3. 3. Two and 4 hr after feeding, large electrophoretically-immobile lipoproteins, corresponding to chylomicra, were detected. 4. 4. Isolated d = 0.96 lipoproteins were 80% triacylglycerol; thus confirming the chylomicra-nature of these particles. 5. 5. The presence of triacylglycerol-rich chylomicra in the serum of trout suggests that exogenous lipid is, in part, transported to the body tissues of these animals in a manner similar to mammals.
