Shannon entropy of a european seabass (Dicentrarchus labrax) system in response to feed polluted with different concentrations of MeHg: a machine vision approach
2017
The present work explores the capacity of a machine vision system to detect deviations in the Shannon entropy (SE) of a European seabass (Dicentrarchus labrax) biological system in response to MeHg contaminated feed. Three groups of fish were exposed for 2 weeks to 0.5, 5 and 10 ppm of methylmercury (MeHg) in the feed and compared to a group whose feed was not artificially contaminated. No mortality was observed during the 2 weeks experimental period. The SE of the experimental cases was modified by the presence of MeHg, confirming our previous works. However, no clear dosedependent responses of the systems' SE to MeHg administration were detected during the 2 weeks period, although there was a different tendency in the evolution of SE during the experimental period between the non-exposed group and the exposed ones.
