Effect of food concentration on protein and carbohydrate production during larval development of the sea urchin Lytechinus variegatus.(Report)

Journal of Shellfish Research | December 1, 2007| | Copyright

ABSTRACT Changes in protein and carbohydrate content during larval development of Lytechinus variegatus were measured under two diet conditions, low concentration (600 algal cells [ml.sup.-1] [day.sup.-1]) and high concentration (6,000 algal cells [ml.sup.-1] [day.sup.-1]) to determine the larval stage at which these proximate constituents showed significant changes under different conditions of food availability. In terms of morphology, larvae under the high concentration diet developed fully and metamorphosed after 30 days, whereas under the low concentration diet, some ...
