Effect of Eyestalk Ablation and Eyestalk Extract Injection on Oxygen Consumption in the Crab, Ocypode macrocera (H. Milne-Edwards 1852)

摘要

The effects of eyestalk ablation and eyestalk extract injection on oxygen consumption of Ocypode macrocera were studied on 30 specimens over a period of 10-days. Statistical analysis of the results show significant differences between stalked and destalked animals as well as stalked and eyestalk extract injected ones. Oxygen consumed in destalked animals was higher than in stalked ones, whereas oxygen consumed by eyestalk extract injected animals was lesser than stalked ones. The differences were discussed on the hormonal basis.
