Measures against accidental trapping of seabirds in fishing gear

Seabirds feeding on fisheries discardFor hundreds of years fishermen and seabirds have been sharing the sea, as collaborators, rather than competitors. However, the introduction of modern fishing gear and practices, and their increasing use has disturbed this balance at the expense of seabirds. Seabird mortality by accidental trapping in fishing gear (seabird bycatch) is a worldwide phenomenon which has been identified to be among the major threats to seabirds together with overfishing and degradation of marine habitats.

Mediterranean ShagThe Aegean and Ionian Sea, as the rest of the Mediterranean Sea, are no exception in this matter. In Greece, all seabird species including those of conservation concern, such as the Mediterranean Shag and the Audouin’s Gull, are victims of seabird bycatch. Although the problem is well known in Greece, up until present LIFE project, no systematic assessment of bycatch has been carried out, meaning that the extent of accidental trapping of seabirds in the fishing gear, and therefore its impact on the national populations of seabirds species have not been yet determined.

The collaboration with fishermen is vital for reducing seabird bycatch Recording of seabird bycatch in the Ionian Sea

This information will be evaluated in order to determine the main factors affecting seabird bycatch and to propose, in collaboration with fishermen, alternative fishing gear and practices that reduce the risk of seabird bycatch. For this purpose, a series of meetings with fishermen and an information dissemination campaign will be carried out.
 

Results:

The collection of data for the assessment of seabird bycatch is being implemented by the TEI of Ionian islands in the Ionian Sea and by the HCMR in collaboration with HOS and MOm in the Aegean Sea.

Until the summer of 2010, 127 fishing trips with on-board observers have been carried out in all major fishing areas of the Aegean and Ionian Sea.

Additional information is being collected through questionnaires for fishermen (pdf Διαβάστε εδώ το pdf)

The project is implemented by the Hellenic Ornithological Society, in collaboration with the Hellenic Society for the Study and Protection of the Monk Seal (ΜΟm), the Hellenic Centre for Marine Research (HCMR), the Technological Institution (TEI) of Ionian Islands and the Portuguese Society for the Study of Birds (SPEA), with the financial support of the European Commission and the co-financing of the A.G. Leventis Foundation.
