| Abstract | This study investigated the effects of prolonged starvation on oxygen consumption, ammonia-N excretion, and bloodchemistry of the horseshoe crab, Carcinoscorpius rotundicauda. Starvation over a period of 7 weeks showed no significantdifference of body weight between the starved and fed groups. The oxygen consumption rate decreased during weeks 1-4 andthen significantly increased after week 6 of starvation. Starvation also resulted in a significant increase in ammonia-N rate fromweek 3 to 7. The O:N ratios were significantly reduced in the starved group from week 3 to 7. Starving induced the reduction ofhemolymph osmolality from week 5. Hemolymph Na+and Cl? of the starved group decreased from week 4 for Na+and fromweek 3 to 7 for Cl?, while hemolymph K+increased from week 4 to 7. Hemolymph K+of both groups was hyperionic during theexperiment. Thus, horseshoe crab can survive starvation for more than 7 weeks. |
