“…One of the two studies identified in our review (S18 Table) showed no change in ALT/AST levels of Gadus morhua and a mixed response in Platichthys flesus when exposed to the same sediment in the field [97]. The other laboratory study reported a significant increase in ALT/AST levels following dietary exposure to Cd in Rachycentro canadum [142]. The lower number of studies, combined with their inconsistent results, means that these biomarker are not recommended for assessing fish health in Gladstone Harbour.…”

“…Haematocrit results in two field studies were inconsistent though, with one study reporting no response to metal exposure and the other a significant increase [97, 108]. Following dietary exposure in the laboratory, a significant change was observed when fish were fed Cd but not for Se [142, 145]. Erythrocyte counts did not change following exposure to sediment or water contaminated with metals [97, 127, 142].…”

BackgroundBiomarkers have been used extensively to provide the connection between external levels of contaminant exposure, internal levels of tissue contamination, and early adverse effects in organisms.ObjectivesTo present a three-step protocol for identifying suitable biomarkers to assess fish health in coastal and marine ecosystems, using Gladstone Harbour (Australia) as a case study.MethodsPrior to applying our protocol, clear working definitions for biomarkers were developed to ensure consistency with the global literature on fish health assessment. First, contaminants of concern were identified based on the presence of point and diffuse sources of pollution and available monitoring data for the ecosystem of interest. Second, suitable fish species were identified using fisheries dependent and independent data, and prioritised based on potential pathways of exposure to the contaminants of concern. Finally, a systematic and critical literature review was conducted on the use of biomarkers to assess the health of fish exposed to the contaminants of concern.Results/DiscussionWe present clear working definitions for bioaccumulation markers, biomarkers of exposure, biomarkers of effect and biomarkers of susceptibility. Based on emission and concentration information, seven metals were identified as contaminants of concern for Gladstone Harbour. Twenty out of 232 fish species were abundant enough to be potentially suitable for biomarker studies; five of these were prioritised based on potential pathways of exposure and susceptibility to metals. The literature search on biomarkers yielded 5,035 articles, of which 151met the inclusion criteria. Based on our review, the most suitable biomarkers include bioaccumulation markers, biomarkers of exposure (CYP1A, EROD, SOD, LPOX, HSP, MT, DNA strand breaks, micronuclei, apoptosis), and biomarkers of effect (histopathology, TAG:ST).ConclusionOur protocol outlines a clear pathway to identify suitable biomarkers to assess fish health in coastal and marine ecosystems, which can be applied to biomarker studies in aquatic ecosystems around the world.

“…Krissanakriangkrai et al (2009) also reported that sediment and swamp eels in the Mae Tao River contain Cd that exceeds the maximum level allowed in sediment and fish. When fish are consumed by humans with high concentrations of Cd, around 3-7% of the ingested Cd is absorbed (Liu et al, 2015). Therefore, the level of cadmium in aquatic organisms such as fish must be given attention.…”

ABSTRACT. Cadmium (Cd) is produced mainly as a by-product of zinc mining. In Thailand, the largest zinc mine is located in the Mae Sot district, Tak Province. Samples of Monopterus albus were collected from paddy fields in 4 sites, three downstream and one upstream from the zinc mine. The upstream site was considered to be uncontaminated while the three downstream sites were considered to be contaminated with Cd. Studies on the accumulation level of cadmium were conducted on the liver of the fish using the atomic absorption spectrophotometer technique. The metallothionein (MT) gene expression level in the liver, as a potential biomarker for long-term Cd exposure in their natural habitat, was also assessed. The level of hepatic MT gene expression was performed by quantitative real-time PCR. The result showed that Cd accumulation in the liver was much higher in swamp eels collected from the downstream sites when compared to those collected from the upstream site. The hepatic MT level in the upstream site was 0.75-fold, 2 M. Wahid et al. Genetics and Molecular Research 16 (3): gmr16039748 while the other three downstream sites were 0.36-, 4.44-and 0.94-fold. There is no parallel correlation between hepatic cadmium levels and hepatic MT gene expression. This study then suggests that MT gene expression biomarkers might be not suitable for swamp eels with prolonged exposure to Cd.
