Abstract
The influence of sinus and mandibular glands on the metabolism of the Ocypode macrocerawas studied. Carbohydrate content of heart, hepatopancreas, muscles and hemolymph of eyestalk extract injected crabs was significantly higher than that of control, ablated and cheliped injected crabs (P<0.05). Protein content of heart, gill, muscles and hemolymph of ablated crabs was also significantly higher than that of control, eyestalk extracted injected and cheliped injected crabs (P<0.05). The result showed that the lipid content in the hepotopancreas (2.46 mg/g) and ovary (3.24 mg/g) of ablated animals was significantly higher when compared to control, eyestalk extract injected and cheliped injected crabs. Similarly carbohydrate content of gill, hepatopancreas and muscles of mandibular injected crabs was significantly higher than that of control and cheliped injected crabs (P<0.05). Protein content of heart, gill, hepatopancreas, muscles and hemolymph of mandibular injected crabs was significantly higher than that of control and cheliped injected crabs. The result showed that mandibular extract injection decreased the lipid content of hepatopancreas and muscles.
