The population numbers of Baltic seals have recently increased. Along with the growing seal populations, seal induced damages to fisheries, i.e. both fish catch loss and damage to the gear, have increased. On the other hand, unknown numbers of seals face unintended by-catch mortality. This has caused a conflict between seals and coastal fisheries.
ECOSEAL studies the spatio-temporal variation of the diet of grey seals in the Central Baltic region in Finland, Sweden and Estonia. During the project diet composition obtained from different methods will be synthesized and compared. Thus the ecological role of grey seals in the Baltic Sea can be clarified.
