About 4,800 European eel fry were released into a lagoon in the province of Cádiz as part of the Eel Management Plan being implemented by the Local Administration.
In the medium term, the local authority expects that the Plan facilitates the restoration of habitats and of populations for 40 per cent of adult eels to be able to escape into the Sargasso Sea, in the Atlantic Ocean.
The Andalusian Administration seeks to ensure that the species completes its life cycle from the moment they enter the rivers as elvers until their escape as an adult eel to the sea and their reproduction in an area of the central Atlantic.
The Minister of Environment of the local authority of Andalucía, José Juan Díaz Trillo, who participated in the release of the eel fry indicated that this Plan includes the restocking with specimens of up to 12 centimetres in size in those places where they have no access to due to the fragmentation of courses and habitats in general.
The released eels are between 11 and 12 centimetres long and weigh approximately 12 kilograms.
Díaz Trillo noted that the wetlands in Cádiz are suitable for their location, conditions and monitoring. He explained that the eels will remain in the lagoon until they reach the migration age, that is to say, until they are about seven years old.
As as soon as they reach their maturity, they will be captured again and they will be moved to the estuary of the Guadalquivir River. There they will be released so that they can begin their journey to the Sargasso Sea, where they will reproduce.
The specimens that have just been released were provided by the Centre for Native Species Breeding in Los Villares (Córdoba), belonging to the Ministry of Environment.
