Conventia de la Washington (CITES) www.cites.org va avea cea de 14-a Conferinta a Partilor la Haga (Olanda), intre 3 si 15 iunie 2007. Germania propune o restrictionare a comertului international cu anghile, in incercarea de a contribui la suprimarea factorilor care duc la scaderea sanselor de supravietuire a anghilei in Europa.

Peter The eel {Anguilla anguilla (LINNAEUS, 1758)} the only representative of the family Anguillidae living in the country has faced serious difficulties in the recent decades, therefore it is strongly recommended to introduce more rigorous regulation in order to improve its ecological conditions. Eels spawn in the Western part of the Atlantic Ocean, in the Sargasso Sea, in a depth of about 100-200 meters. The hatching larvae (leptocephalus larvae) are 5 mm long, shaped like a willow-leaf. They arrive to the European shores in about two years drifting with the ocean streams. In the meanwhile they change to the so-called glass eel state, with a transparent, cylindrical body. Their pigmentation develops gradually: it takes another year to turn into bronze eels, while traveling upstream on the rivers. Their inland water life phase begins. This bronze eel state lasts for 1-2 decades, until becoming sexually mature, when their seeward migration starts. Thanks to their good adaptability and strong migration aptitude, they could be found in larger and smaller rivers as well, and also in various lakes, river arms and larger channels eels were common in all kinds of inland waters. Originally this species is common in the European shores of the Atlantic Ocean and the Mediterranean Sea; it is rare in the Black Sea and its rivers, but it is definitely autochthonous. The regional eel population has come close to become extinct as a result of the regulation of rivers, the Iron Gate on the Danube and massive dieing of the last decade. Due to the specific development cycle of the eel (catadromous species), it has become more and more difficult for the progeniture to return to its natural habitats, partly because of the regulation, dams and other interventions in the catchment area, and partly because of the higher pollution levels. Similar to sturgeons (Acipenseridae), the self-sustaining populations of eels are a victim of river management practices. On the Western European market there is a significant demand for eels. Considering its economic profitability, commercial and recreational fisheries tried to counteract this tendency with artificial populations. As a result, eels were caught by anglers in a higher proportion for a short period. Nevertheless, currently natural populations are in decline, as overfishing is also posing a threat to eel populations, beside the changes in the integrity of river systems. As a result of these complex factors, the species become endangered. For the preservation of the species, the introduction of effective restrictive, control and conservation measures are recommended. In the long term the only solution is the restoration of rivers acting as an ecological corridor, in accordance with the approach of the Water Framework Directive of the European Union. Recommendation: Support the proposal of Germany on behalf of the European Community to include the eel in Appendix II of CITES, in order to restrict its trade. This measure would contribute to the preservation of the remaining endangered populations.
