American eel (Anguilla rostrata) and European eel (Anguilla anguilla) populations have declined since the 1980s prompting concern about their status and the causes of decline, but stock assessment approaches to estimate effects of fishing on these populations are lacking. Since 1964, 16% of United States commercial American eel harvest came from the Potomac River, yet American eel abundance, pr...

Eels use the swimbladder for buoyancy control. The ductus pneumaticus connecting esophagus with is closed soon after initial opening of in glass eel stage, so that eels are functionally physoclist. Subsequent filling achieved by activity gas gland cells epithelium and countercurrent concentration rete mirabile. Gas produce release lactic acid CO2. In blood, acidification induces a oxygen from h...

This article contains data related to the two research articles titled Transcriptomic and iTRAQ proteomic approaches reveal novel short-term hyperosmotic stress responsive proteins in the gill of the Japanese eel (Anguilla japonica) (Tse et al. [1]) and iTRAQ-based quantitative proteomic analysis reveals acute hypo-osmotic responsive proteins in the gills of the Japanese eel (Anguilla japonica)...

The European eel Anguilla anguilla is a critically endangered catadromous species. There an urgent need for close surveillance of the populations that are still viable in rivers. species difficult to observe freshwater because its bottom-dwelling behavior; currently employed methods monitoring Europe based on physical capture individuals stressful and may cause mortality. Here, we present new h...

Some physicochemical properties of the L-fucose-binding lectin from the serum of the European eel (Anguilla anguilla) were determined. The lectin is a dimer composed of identical subunits of Mr approx. 40000. In agreement with previous results [Horejsí & Kocourek (1978) Biochim. Biophys. Acta 538, 299-315], the subunit was shown to comprise two non-glycosylated polypeptides of Mr approx. 20000 ...

Unlike the whole body oxygen affinity, which adapts readily to environmental oxygen tensions, haemoglobins, prepared from normoxic- and hypoxic-accimated eels (Anguilla anguilla) show no adaptive changes in oxygenation properties or in multiplicity. Hypoxic acclimation is, howeveer, accompanied by a strong decrease in red cell nucleoside triphosphates, particularly guanosine triphospphate (GTP)...

Probably half of all animal species exhibit a parasitic lifestyle and numerous parasites have recently expanded their distribution and host ranges due to anthropogenic activities. Here, we report on the population genetic structure of the invasive nematode Anguillicola crassus, a parasite in freshwater eels, which recently spread from Asia to Europe and North America. Samples were collected fro...

An unexploited mixed species eel stock (Anguilla australis and A. dieffenbachii) in a Waikato pastoral stream, and its modification by fishing pressure.

In a study of the parasite fauna of the European eel (Anguilla anguilla L.) in northwest Spain, we found frequent mixed infection of branchial tissues by the myxosporidian Myxidium giardi (prevalence 95%) and by two monogeneans (Pseudodactylogyrus anguillae and P. bini; joint prevalence 56%). All three species are common parasites in this host. In one of the 323 eels examined, hyperparasitism o...
