| the effect of foraging and ontogeny on the prevalence and intensity of the invasive parasite anguillicola crassus in the european eel anguilla anguilla. | infection patterns of the invasive anguillicola crassus nematode were investigated in a population of the european eel anguilla anguilla where parasite invasion is very recent, loch lomond, scotland. intensity levels of the parasite were associated with differences in fish ontogeny and trophic ecology. although eels foraged on both fish and invertebrates, individuals which were smaller and fed on invertebrates (>70% contribution to diet) were found to contain a greater number of swim bladder par ... | 2017 | 28084623 |
| lipid increases in european eel (anguilla anguilla) in scotland 1986-2008: an assessment of physical parameters and the influence of organic pollutants. | recruitment of the european eel (anguilla anguilla) has fallen steadily in recent decades, with current levels understood to be at around 5% of those in the 1970s, and the species is now widely recognised as being endangered. changes in ocean currents, climate shifts, habitat loss, overfishing, barriers to migration, increased predation, plastic litter and exposure to chemicals have all been postulated as potential causative factors. several studies have shown a general decline in eel quality (l ... | 2015 | 25651809 |
| persistent organic pollutants (pcb, ddt, hch, hcb & bde) in eels (anguilla anguilla) in scotland: current levels and temporal trends. | eels are an ideal biomonitor for persistent organic pollutants (pops) because of their high lipid content, longevity and tendency to remain within a defined range during their freshwater life phase. this study investigated concentrations of pops in eels (anguilla anguilla) from 30 sites across scotland, including polychlorinated biphenyls (pcbs), polybrominated diphenyl ethers (bdes), ddt (and metabolites), hexachlorocyclohexanes (alpha, beta, gamma-hch), hexachlorobenzene (hcb), hexachlorobutad ... | 2010 | 20471146 |
