Tumlarna i \u00d6resund och Kattegatt f\u00f6rsvinner i snabb takt och nu larmar forskarna, enligt\u00a0SVT Helsingborg<\/a>.<\/strong><\/p>\n\n\n\n

– Det g\u00e5r verkligen stupr\u00e4tt utf\u00f6r och det m\u00e5ste vidtas \u00e5tg\u00e4rder, s\u00e4ger Julia Carlstr\u00f6m, forskare vid Naturhistoriska riksmuseet.<\/p>\n\n\n\n

Enligt henne d\u00f6r 900 tumlare \u2013 som \u00e4r v\u00e4rldens minsta val \u2013 i fisken\u00e4t varje \u00e5r. Samtidigt har hon r\u00e4knat ut att max 24 tumlare kan d\u00f6 varje \u00e5r som bif\u00e5ngst om populationen ska finnas kvar p\u00e5 sikt.<\/p>\n\n\n\n

De st\u00f6rsta hoten mot tumlarna i svenska och danska vatten \u00e4r att de av misstag fastnar i fiskegarnen, enligt Johanna Stedt, doktorand vid Lunds universitet. Viktiga \u00e5tg\u00e4rder \u00e4r d\u00e4rf\u00f6r att sluta fiska med bottengarn och att ha ljudskr\u00e4mmor p\u00e5 n\u00e4ten.<\/p>\n\n\n\n

Antalet tumlare har n\u00e4stan halverats p\u00e5 20 \u00e5r. Vid millennieskiftet fanns det omkring 28 000 tumlare i Kattegatt och \u00d6resund. Den s\u00e5 kallade B\u00e4lthavspopulationen har i dag sjunkit till 14 000. I \u00d6stersj\u00f6n \u00e4r l\u00e4get v\u00e4rre: d\u00e4r finns ungef\u00e4r 500 individer kvar, enligt Johanna Stedt.<\/p>\n","protected":false},"excerpt":{"rendered":"
