“…Thus, it seems possible that this specialised hematophagous parasite is able to excrete the mercury in detoxication processes. The same trends and results were published by Sures et al (1994) in relation to lead concentrations in A. crassus (mean 0.02 ± 0.01; range 0.01 -0.03 in µg g -1 wet matter), and in liver of naturally infected (n = 8) eels (0.18 ± 0.05; range 0.12 -0.28) from the river Weser (Germany). The size (age groups) of adult worms did not differ in this aspect.…”

“…Values of the ratio (R) vary according to Tenora et al (1999) for males of A. crassus vs. eel muscle in the range of 7.8 -15.1, for females of A. crassus vs. muscle between 2.3 -4.9, only. For the mercury, according to our results the efficacy of accumulation and the values of concentrations in A. crassus are comparably low as for the lead (Sures et al 1994). According to Tenora et al (2000) the only species of the nematode, Philometra ovata Zeder, 1803, infecting the body cavity of cyprinid fishes is known to accumulate more heavy metals than the muscle of the host, i.e., the bream (Abramis brama L.).…”

Palíková M., V. Baru‰: Mercury Content in Anguillicola crassus (Nematoda) and its Host Anguilla anguilla. Acta Vet. Brno 2003, 72: 289-294. Mercury content in parasite-host system (Anguillicola crassus and Anguilla anguilla) was studied in the Koryãany Reservoir (Czech Republic). The swimbladder nematode contained the lowest mercury levels (0.050 -0.183mg kg -1 wet weight), (p < 0.05), compared to muscles (0.162 -0.827) and the liver (0.175 -1.430) of the fish definitive host. The mercury concentrations in the definitive host were higher in the liver, but not significantly different from muscle concentrations. Regression analysis indicated a positive ratio between mercury concentrations in the liver and the total body length of the fish. In eels from the reservoir under study the mercury content in fish muscles exceeded the hygienic limit in one fish specimen only. Muscle, liver, parasite-host system

“…Lower accumulations were seen in cestode larvae in the body cavity of fish intermediate hosts (Gabrishanska and Nedeva 1996;Pascoe and Cram 1977). In contrast, nematode parasites, Anguillicola crassus, accumulated less Pb than their host, the eel Anguilla anguilla (Sures et al 1994). However, other studies of nematodes (Tenora et al 1999(Tenora et al , 2000 indicate greater concentrations of metals in the nematode than in the fish host.…”

The sea bream's nematode and Sparus aurata, sampled from the Iskenderun Bay, Mediterranean, in March 2008 were analyzed by inductively coupled plasma-atomic emission spectrometry for their some heavy metal (Cd, Cr, Cu, Fe, Hg, Mn, Mg, Pb, and Zn) levels. The metal concentrations of the parasites were compared to different organs (liver, muscle, gill, intestine, and skin) of the fish hosts. There were significant differences in Cd, Cr, Cu, Fe, Mn, Zn, Hg, Mg, and Pb concentrations in tissues of fish and its parasite. The parasite Cd, Cu, and Pb concentration was higher than the other tissues. Furthermore, significant differences were detected in the heavy metal accumulations between the parasitized and unparasitized fish tissues in Cd, Cu, Hg, and Pb concentrations. The Cd, Hg, and Pb concentrations were found in fish muscle at mean concentrations over the permissible limits proposed by the Food and Agriculture Organization.

“…Furthermore, as eels are able to withstand environmental pollution and tend to accumulate heavy metals to a very high degree (e.g. Mason and Barak 1990;Sures et al 1994), it seems likely that this species is not sensitive enough to show alterations in its immune response at low levels of Cd pollution. The toxicity of PCB 126 seems to be related to a structural similarity to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), the most toxic of all halogenated aromatic hydrocarbons (HAH) (Regala et al 2001).…”

The effects of contaminants in European eel: a review

2009

View full text Add to dashboard Cite

European eel (Anguilla anguilla (L.)) stocks are in decline in most of their geographical distribution and their status is considered below safe biological limits. Recently, there is an increasing awareness that spawner quality might be an essential element in the decline of the species since pollution by bioaccumulating chemical substances may have a large impact on the reproduction success of the eel. This review gives an overview of the literature on the effects of contaminants on the European eel and on the consequences on the biology and fitness of the eel in order to document the role of pollution in its decline. A variety of contaminants have been found to affect the eel. These contaminants may cause disturbance of the immune system, the reproduction system, the nervous system and the endocrine system and effects were reported on several levels of biological organization, from subcellular, organ, individual up to even population level. More extensive research is needed in order to evaluate how pollutants are detrimental to eel populations. Getting a comprehensive overview of the quality (including contamination levels, biomarker responses, lipid content and condition) of the silver eel population all over Europe seems to be an essential and urgent objective for the European eel management.
