Effects of moulting cycle and nutritional conditions on haemolymph proteins in Carcinus maenas
1.
1. By means of zone-electrophoresis on cellulose acetate, the haemolymph proteins of Carcinus maenas have been separated into three major components: haemocyanin (fraction-D) a glycoprotein (fraction-I), and a glycolipoprotein (fraction-P). No apohaemocyanin was found.
2.
2. Moulting causes a four- to five-fold decrease in haemocyanin concentration. Premoult levels are progressively restored during the intermoult period. At ecdysis fraction-I disappears completely, and reappears about 10 days later.
3.
3. Bleeding causes a marked increase of the ratio, concentration of fraction-I/concentration of haemocyanin.
4.
4. The concentration of fraction-I is highly dependent on the nutritional status. Starvation causes the complete disappearance of the glycoprotein. During a period of excessive feeding fraction-I accumulates in the blood.
