Abstract
Significant reductions in vitellogenin (VTG) and vitellin (VTN) contents were observed in the hepatopancreas, haemolymph, and ovary of the estuarine crab Scylla serrata exposed to naphthalene.
- Naphthalene exposure is associated with decreased levels of vitellogenin in the haemolymph and vitellin in the ovary of crabs.
- The gonadosomatic index (GSI) showed a decreasing trend in crabs exposed to naphthalene, indicating potential reproductive disturbances.
- Alterations in vitellogenic proteins and GSI may serve as biomarkers for assessing reproductive impacts of environmental pollutants.
