Among others, the introduced parasite Anguillicola crassus is thought to play an important role in the decline of eel populations. These nematodes have been shown to negatively affect many fitness-related traits in eels, e.

- Analysis of fish otoliths from the Taiaro lagoon and nearby ocean reveals that larval nuclei show isotopic equilibrium (delta 18O), indicating that lagoon fish have completed their life cycles in a closed environment.
- The outer parts of otoliths present slight isotopic disequilibrium (< 0.2@1000) due to vital effects, suggesting some influence of biological processes.
- All delta 13C values indicate significant isotopic disequilibrium, which is linked to metabolic activity in the fish.
