✦ Synopsis

Effects of Starvation on the Principal Biochemical Constituents of the Sea Urchin Arbacia lixula. I. Resting Stage

The effects of starvation on the levels of protein, carbohydrates and lipids of three principal reserve compartments -the gonads, digestive tract, and testhave been studied in the resting stage of the sea urchin Arbacia lixula. Variations of these levels were observed during 1 month's starvation. Analysis of covariance revealed the following significant changes: (a) a decrease in carbohydrates of the test and digestive tract; (b) a decrease in lipids of the test and gonads; (c) an increase in proteins of the gonads. A decrease in the carbohydrates and lipids of the test during the first week of starvation emphasizes the importance of the test as a storage organ.
