Freshwater planarian are emerging as a valuable in vivo model for (eco) toxicological studies, but the lack of harmonization of procedures between laboratories remains a challenge. This study aimed to optimize, automate and select the best behavioural tests and analyse the potential of different planarian species as models for toxicological assessment. We implemented four tests: exploration, photomotor response, Tapping and Planarian Light Dark Test, on different planaria species using the DanioVision system.

Article Synopsis
- Meiobenthic nematodes are increasingly recognized as important models for biomonitoring and ecotoxicology, yet their sensitivity to oxidative stress has not been explored until this study.
- The research successfully cultured Metoncholaimus pristiurus as a single species by manipulating sediment grain size with a biosubstrate derived from Sepia officinalis.
- The study established new protocols for assessing oxidative stress through enzyme activity, showing clear responses to stressors like zinc and permethrin, suggesting that M. pristiurus may serve as an early indicator of environmental stress.
