Abstract: | Nonylphenol (NP), a xenoestrogen ubiquitously found in aquatic ecosystems, is of high environmental concern. The present workassessed the e ects of exposure to NP on locomotor activity and social behavior in male and female zebrafish (Danio rerio), to evaluatethe possible hazard of NP to fish behavior and to pursue a potential biomarker of NP contamination. Fish were randomly divided into sixgroups. Five groups were receiving 0.1, 1, 10, 50 and 100 g/L nominal concentrations of NP for 60 days, respectively. A sixth controlgroup was given the same treatment as the other five groups, but no NP. Locomotor activity, aggressive behavior, group preference andleaving shoal were examined. NP exposure showed marked influence on locomotor activity of the male zebrafish, whereas that of thefemale was not significantly a ected by NP. Aggressive behavior and group preference were significantly a ected by NP exposure inboth male and female groups. Locomotor activity and aggressive behavior of the male and group preference of both male and femalezebrafish were clearly inhibited at 100 g/L NP. No significant alteration in leaving shoal was observed under NP exposure. The resultssuggested that changes in locomotor activity and aggressive behavior of the male and group preference of both male and female maybe used as an ecologically relevant integrative biomarker of NP contamination. |
