“…Bioaccumulation factors for sediment (BAF sed ) and water (BAF water ) were mostly determined for Cd, Cu and Zn, with BAF sed values for Cd ranging from 0 in Cathorops spixii [76] to 521 in Liza microlepis [79], for Cu from 0.13 for Stromateoides argenteus [81] to 304 for Liza saliens [80], and for Zn from 0.21 in Johnius belengeri [78] to 447 in L . saliens [80].…”

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.

“…This is largely due to the fact that tiger prawns have the ability to detoxify and remove some metals from the body by granule formation and excretion and to prevent other metals from entering major soft tissues (Vogt and Quinitio, 1994). High level of biological essential metals like Cu, Fe, and Zn is also due to the fact that these elements are easier to accumulate in tissues than the non essential meals such as Cd and Pb (Qiu, 2015). Results also showed that prawns from Site 7 (Lindi) contained highest levels of Cd, Cu, Mn and V, while those from Site 4 (Dar es Salaam) contained highest levels of Hg, Ni, and Zn.…”

“…Branchiomma are annelids that are widely distributed globally, particularly in coastal lagoons, rocky shores, marinas, piers, and harbors (Bastida‐Zavala, Buelna, De Leon‐Gonzalez, Camacho‐Cruz, & Carmona, ). Species of Ulva, which are chlorophyte green algae, are also common benthic organisms in Daya Bay (Qiu, ). Both Branchiomma and Ulva are readily obtained by predators and herbivores.…”

A knowledge of fish diets can contribute to revealing the trophic role and ecological function of species in aquatic ecosystems. At present, however, there are no efficient or comprehensive methods for analyzing fish diets. In this study, we investigated the diets of juvenile Scatophagus argus collected near a wharf in Daya Bay, China, by dissection and high‐throughput sequencing (HTS) using the 18S rDNA V4 region. Microscopy disclosed large amounts of bryozoans and unrecognizable detritus. In contrast, HTS analysis indicated that the fish diets were considerably more diverse than visual inspection suggested. After eliminating fish sequences, approximately 17,000 sequences from taxa in nine phyla (Ciliophora, Bryozoa, Annelida, Bacillariophyta, Chlorophyta, Arthropoda, Dinoflagellata, Tunicata, and Phaeophyta) were identified from the analysis of stomach contents. Twenty‐one food categories were identified, most of which (95.2%) were benthic fouling organisms that could easily be collected around wharfs. These consisted of bryozoans (31.9%), ciliates (45.7%), polychaetes (14.6%), and green algae (3.0%). Therefore, to adapt to anthropogenic habitat modification, the fish had probably shifted from planktonic to benthic feeding. The prevalence of fouling organisms in the stomachs of juvenile S. argus indicates that the fish have responded to habitat changes by widening their food spectrum. This adaptation may have increased their chances of survival. The fouling organisms that inhabit highly perturbed coastal ecosystems could represent a food source for animals at higher trophic levels. Our results accordingly suggest that human activity might significantly influence fish feeding behavior and material transfer along the food chain.
