Title

Study of changes in metallothionein concentration of ghost crab (Ocypode saratan) in Gwater and Chabahar mangrove forests in two periods of pre-monsoon and post-monsoon

Pages

  257-270

Abstract

 The aim of this study was to compare the accumulation of Heavy Metals copper, zinc and cadmium and to investigate the changes of Metallothionein as a biomarker of contamination in the gill tissue of the Ghost Crab Ocypode saratan in the two time periods before Monsoon (May) and after Monsoon (November) in mongrove forests. Chabahar and Gwater Bay was done in 2019. The results of the study showed that in both pre-Monsoon and post-Monsoon seasons the pattern of metal accumulation in the gill tissue of the Ghost Crab is zinc> copper> cadmium. The mean concentrations of copper, zinc and cadmium were obtained in the pre-Monsoon and post-Monsoon seasons at Chabahar station, 173. 6 ± 3. 83, 186. 43 ± 3. 1, 0. 095 ± 0. 008, respectively and 156. 7± 4. 15, 175. 13 ± 2. 8, 0. 026 ± 0. 003 and in Gwater station the average concentrations of copper, zinc, cadmium in the two pre-Monsoon and post-Monsoon seasons were respectively 237. 03 ± 6. 4, 231. 8 ± 1. 8, 0. 048 ± 0. 003 and 205. 9 ± 6. 34, 253. 2 ± 2. 13, 0. 037 ± 0. 015 μ g/g dry weight. The mean levels of Metallothionein in pre-Monsoon and post-Monsoon season in Chabahar station were 2. 02 ± 0. 01 and 0. 1 ± 0. 06, respectively, and in goiter station were 2 ± 0. 02 and 0. 12 ± 0. 02, respectively. Comparison of Metallothionein levels between Chabahar and Gwater stations was not significant (P<0. 05). But in both stations separately between the two pre-Monsoon and post-Monsoon seasons, there was a significant difference (P<0. 05). Correlation between Metallothionein and metals showed that there was no correlation between Metallothionein and the studied metals. Therefore, according to the observations, changes in the concentration of Metallothionein in this species are not affected by Heavy Metals and can be due to changes in the environmental conditions of the seasons.
