“…In contrast, both the AK and reference populations of mummichogs accumulated a substantial amount of Zn. Compared to other metals including Cu, a large amount of Zn in mummichogs is usually deposited in calcified structures such as scales (Sauer and Watabe, 1989), suggesting that the temporary deposition of excess Zn in calcified structures may be a detoxification strategy for fish.…”

Intracellular partitioning of trace metals is critical to metal tolerance in aquatic organisms and may also influence metal trophic transfer in ecosystems. In this study, we tested the relevance of metal (Cd, Cu, Pb, and Zn) intracellular partitioning in prey as an indicator of metal trophic availability to benthic forage fish, mummichogs (Fundulus heteroclitus), in chronically metal-polluted salt marshes in New York, USA. Two common prey of mummichogs in the study area, Palaemonetes pugio and Nereis acuminata, generally stored increasingly higher proportions of non-essential metals (particularly Pb) in insoluble (less trophically available) cellular components, as the whole body burdens increased. In contrast, intracellular partitioning of essential metals (Cu and Zn) in invertebrate prey varied relatively little among sites. Differential Cd and Pb intracellular partitioning patterns within P. pugio among sites were significantly associated with Cd and Pb whole body burdens in mummichogs, respectively (i.e., prey-driven bioreduction of metals), while bioaccumulation of Cu and Zn in mummichogs was similar among populations. The findings in this study suggest that metal intracellular partitioning within prey may be partially responsible for metal trophic availability to a predator in metal-polluted habitats, while there was also evidence that some predator-dependent processes may offset differential trophic availabilities from prey.

“…Rashed suggested that scales (and also gills) exhibited highest levels of Pb as they were in direct contact with contaminated water and sediment. Furthermore, Sauer and Watabe (1989) noted the tendency of Pb (and also Zn and Mn) to accumulate in scales of mummichog Fundulus heteroclitus more readily and at higher levels than other heavy metals (Cd and Cu), which showed little or no accumulation.…”

Scales, in particular, are convenient as they can be taken repeatedly from the same fish and are chemically stable for a long time, allowing analysis of archived material.…”

We examined the relationship between muscle and scale mercury (Hg) and lead (Pb) concentrations in chub Squalius cephalus L. from six riverine sites in the Czech Republic in order to determine whether scale analysis alone could provide a nonlethal and convenient method for prediction of heavy metal concentration in muscle tissue. Our results confirm tissue-specific heavy metal accumulation in chub, with Hg tending to accumulate primarily in muscle tissue and Pb in scales. We found no significant relationship, however, for concentrations of either Pb or Hg between muscle tissue and scales of chub. Our results indicate that scales cannot be used for predicting heavy metal contamination in muscle of chub and we recommend, therefore, that muscle biopsy methods continue as the preferred method of analysis.

“…The hard body structures of animals such as the otolith, scales or spines are widely considered as bio-indicators of the water quality (Campana, 1999;Sauer and Watabe, 1989;Trueman and Moore, 2007), and in contrast to soft tissues, they are routinely sampled in many countries for stock assessment and catalogued for future reference. Therefore, microchemistry provides a novel technique to investigate different aspects of fishing mortality as well as determining the origin of fish (both wild and artificiallyreared) in historical samples.…”
