Tutkimuksessa selvitettiin merimetson (Phalacrocorax carbo (L.)) ravintokohteita ja niiden suhteita sek\u00e4 arvioitiin kalankulutusta. Merimetson ravintoa analysoitiin oksennuspallojen avulla. Tutkimus k\u00e4sitti kaikki rannikkoalueet Per\u00e4merelt\u00e4 Suomenlahdelle. Koko maan tasolla merkitt\u00e4vimm\u00e4t merimetson ravintokohteet olivat ahven (Perca fluviatilis L.), kiiski (Gymnocephalus cernuus (L.)), s\u00e4rki (Rutilus rutilus (L.)) ja silakka (Clupea harengus membras L.). N\u00e4m\u00e4 lajit muodostivat yhteens\u00e4 81 % merimetson ravinnosta massana ja 66 % kappaleina.
