Abstrakt

The wild population of the European eel, Anguilla anguilla, has experienced a severe decline over the past half century. This is probably due to human interference, such as overfishing and destruction of habitats. The European eel is considered critically endangered by International Union for Conservation of Nature and Natural Resources (IUCN) among others and is on the brink of extinction. Focusing on current measures in aquaculture and legislation, this literature study evaluates what can be done to recover the population. Currently, it is not possible to reproduce the European eel in captivity. As a result, the aquaculture is fully dependant on eels caught in the wild. Current conservation efforts are heavily focused on restocking programs, but these do not have a documented effect since mortality rates of the restocked individuals have not yet been accounted for. Until the European eel can be reproduced to a full life cycle in captivity, the only means of reducing the decline is, to our knowledge, stricter legislations. We therefore believe that a complete ban of catching and trading the European eel is a necessity.
