“…In this study, THg in lionfish muscle was significantly higher than in other tissues. This finding is in agreement with earlier work [90][91][92] which supports a general pattern of higher THg in muscle relative to internal organs in fish from lightly contaminated localities which is likely the case with our fish collected in offshore marine waters (>20 km from land). A key limitation of the current study was that methylmercury was not quantified.…”

Invasive lionfish (Pterois volitans/miles) pose a serious threat to marine ecosystems throughout the western Atlantic Ocean and Caribbean Sea. The development of a fishery for lionfish has been proposed as a strategy for controlling populations; however, there is concern about consumption of this species by humans due to its high trophic position and potential for bioaccumulation of mercury. We analyzed total mercury (THg) in tissues of lionfish from two locations on the east coast of Florida. THg in lionfish increased with size and differed by location and sex. THg was highest in muscle tissue and was strongly positively correlated among tissues. THg in lionfish was lower than other commonly consumed marine fishes, and falls into Florida’s least restrictive advisory level. Consumption of lionfish poses a low risk and concerns over mercury bioaccumulation should not present a significant barrier to lionfish harvest.

“…The fact that Hg concentration in muscle of fish captured from lightly contaminated localities is usually higher than that found in their internal organs (liver, kidney) has been reported in studies of common carp ( Cyprinus carpio ) [12], seven species of fish from the Skalka reservoir [24], pike-perch ( Stizostedion lucioperca L.) and bream ( Abramis brama ) from Lake Balaton in Hungary [14], tusks ( Brosme brosme ) captured off the coastline (a lightly contaminated locality) [13], and Odontotesthes microlepidotus from lightly contaminated localities [25]. Mercury distribution in lightly contaminated localities seems to take the following pattern: muscle > kidney > liver > gonads [26, 27].…”

“…Some authors believe that Hg distribution in fish tissues from heavily contaminated and lightly contaminated localities is different [10, 12, 13-16]. This was not corroborated by Wang et al (2005) [17] in their study on frogs ( Rana chensinensis ), or by Honda et al (1983) [9] or Chen et al (2004) [18].…”

Tissue samples from 1,117 fish of 25 species were collected from 1991 through 1996 at 13 locations along the River Elbe. The principal indicator species were perch (Perca fluviatilis) (n=118), chub (Leuciscus cephalus L.) (n=113) and roach (Rutilus rutilus) (n=138). Mercury (Hg) concentrations in muscle and liver were determined by atomic absorption spectrometry. The liver/muscle index in three indicator species from heavily contaminated and lightly contaminated localities were significantly different. In fish from heavily contaminated localities, Hg was deposited preferentially in the liver (the depository for inorganic and organic forms of Hg), while in lightly contaminated areas, it was deposited preferentially in muscle.

“…The Sørfjord is an arm in the innermost part of the Hardangerfjord, and the high level of mercury found in tusk captured further out in the Hardangerfjord was less expected as it was believed that this fjord was less affected by the contamination of mercury than the Sørfjord. Also in fjord systems such as the Nordfjord further north with no known sources of mercury, tusk muscle has been found with elevated mercury concentrations compared with ocean samples [25]. This could indicate that there is more bioavailable methyl mercury in the food web pathways in the fjords versus in the open ocean areas.…”

The tusk (Brosme brosme) is a popular gadoid fish for human consumption, which also is susceptible to mercury accumulation. However, few data of mercury levels in tusk exist, and it is difficult to compare tusk fished from assumed contaminated areas with background levels. The aim of this study was to increase the information of mercury levels observed in tusk from the Northeast Atlantic Ocean. Samples of tusk were collected from seven different localities in open ocean areas, nine along the Norwegian coastal current (NCC), and from two fjord stations. Determinations of mercury in muscle and liver were carried out using inductive coupled plasma mass spectrometry (ICPMS) after microwave-assisted wet digestion. The highest concentrations of mercury in muscle were found in tusk captured from the fjords Hardangerfjord and Sørfjord, and had mean concentrations of mercury at 1.5 and 1.7 mg kg-1 wet weight (ww), respectively, where all of the tusk exceeded EU's upper limit of 0.5 mg kg-1 ww. The lowest concentrations of mercury were observed in tusk captured from the open ocean areas, and the concentrations ranged from 0.08 to 0.30 mg kg-1 ww. Mercury concentrations of tusk captured along the NCC ranged from 0.21 to 0.49 mg kg-1 ww. Mercury concentrations increased with the weight of the tusk, and variance analysis (ANOVA) of weight normalized mercury concentrations showed that there were significant differences in mercury concentrations between tusk collected from the open ocean, NCC and fjords, which indicates that differences in mercury concentration between different areas arecaused by other factors.
