Mercury concentration in the freshwater bonefish Cyphocharax gilbert (Curimatidae) and its parasite the crustacean Riggia paranensis (Cymothoidae)
Fish parasites can accumulate heavy metals reaching higher concentrations than the host and may affect the host's bioaccumulation. The present study compared total mercury concentration in the liver and muscle of Cyphocharax gilbert and in the parasite Riggia paranensis sampled in the middle It...

| description | Fish parasites can accumulate heavy metals reaching higher concentrations than the host and may affect the host's bioaccumulation. The present study compared total mercury concentration in the liver and muscle of Cyphocharax gilbert and in the parasite Riggia paranensis sampled in the middle Itabapoana River, Brazil, also considering the reproductive stages of both fish and parasite. Mean concentrations of mercury in muscle of fish varied from 20.8 ng.g-1 in mature females to 38.1 ng.g-1 in post-spawning females. The mean concentrations in fish liver varied from 60.9 ng/g in post-spawning females to 110.4 ng.g-1 in infested males. The mean concentration of mercury in parasites varied from 26.2 ng.g-1 in specimens carrying early embryo to 39.5 ng.g-1 in specimens with eggs. Positive and significant associations (P<0.05) were found between the total mercury concentrations in parasites and muscle of host (both females and males), and between concentrations in parasites and in the liver of male hosts. These results suggest that R. paranensis can be used to indicate mercury levels in edible parts of C. gilbert. |
