The effect of algal and artificial diets on the growth and fatty acid composition of<i>Crassostrea gigas</i>Spat

Abstract

Crassostrea gigas spat were fed diets of Pavlova lutheri, Dunaliella tertiolecta or Tetraselmis suecica . The D. tertiolecta diet contained no fatty acid longer or more unsaturated than linolenic acid (18:3ω3) and the T. suecica diet was deficient in decosahexaenoic acid (22:6ω3). The algal diets were supplemented with micro-encapsulated triolein, oyster lipid extract or 22:6ω3. Spat were also starved or fed carbohydrate diets.
