ACTION D.1: Monitoring the pilot project of sturgeon restocking

Development of studies to determine Migration behavior in the Ebre River and estuary system, Location of suitable habitats and Movement along migration barriers.

Execution dates: from 01-03-2016 to 31-12-2017

European sturgeon returns to Ebre river

Months and months of international coordination, preparations and preliminary work to bring 4 European sturgeon specimens (Acipenser sturio) to Ebre territory.  Specifically to the facilities that IRTA has in Sant Carles de La Ràpita, where they will be in an adapted tank and will serve, above all, for public awareness and dissemination. With two underwater cameras […]

Eel marking at Ebre river

After data gathering and with anew location for the new river data receivers, this Autumn 2018, PNDE, IRTA and CERM technical experts have been working together in electrical fishing to capture, measure and mark adult eels and free them to track their movements in Ebre river. In addition, the effectiveness of the new fish passes […]

Sea lampreys at Ebro Delta?

LIFE Migratoebre experts are working during this month of September together with a research team from Santiago de Compostela University, leaded by Fernando Cobo, to check if there still are lamprey (fry) populations at the lower Ebre slope. A pilot project about reintroduction of this species at river Ebre will be written up with these results, […]

New radio transmitters and receivers at Ebre river

With the purchase of new ultrasound transmitters and receivers, LIFE Migratoebre team will mark more migratory fish specimen at Ebre river. With these receivers the reading will be easier as it can be connected with the transmitter device from the surface and to compilate data from marked specimen who have passed by upriver or downriver. […]

Monitoring of river receivers

From the 28th to 30th August 2018 specialised divers are working to recover all ultrasound receivers which were placed along the river and at Delta. With this job all receivers will be recovered and replaced by new ones which will allow data reading from the river surface with no need to handle them. With these […]

Eels radio tracking in Ebre river

Last 2017 November some electric fishing was done to catch and tag with radiotransmitters migratory fish, and in particular adult eels. About 60 specimen from this species have been caught and tagged, and will be used to track their movements along Ebre river and also to check how do they use all fish passes created […]

Migratory fish marking and monitoring

During the month of May 2017 electric fishing has taken place in Ebre river to capture migratory fish, mark them with radio trasmitters and release them up-river. At the same time radio receivers have been strategically placed in the river, from Ascó to the mouth. These radio receivers will allow monitoring on these marked fishes […]
