Einmalig: Schakale graben Schlangenaale bei Pelican Point aus

Swakopmund/Walvis Bay (er) • Etliche kleine Seezungen und Schlangenaale sind am Mittwoch am Strand bei Pelican Point nahe Walvis Bay an Land gespült bzw. ins flache Wasser geraten. „Schakale haben die Aale ausgegraben und gefressen. Das habe ich noch nie zuvor gesehen“, sagte Jeanne Meintjes von Eco Marine Kayak Tours gestern im Gespräch mit der AZ.

Laut einer Meeresbiologin, die anonym bleiben möchte, handelt es sich höchstwahrscheinlich um eine Algenblüte oder einen Schwefelausbruch im Atlantischen Ozean, der diese Meerestiere an Land getrieben hat. „Ein solches Phänomen ist zu dieser Jahreszeit nicht ungewöhnlich“, sagte sie und ergänzte: „Eine Angelblüte oder Schwefelausbruch ist oft mit einem Sauerstoffmangel verbunden, weshalb die Tiere im flachen Wasser zu finden sind.“

Einen Tag zuvor haben Brandungsangler hunderte junge Kap-Bastardmakrelen mit Netzen gefangen, die bei Meile 8 nördlich von Swakopmund ins flache Wasser gespült waren. Diese Fischart kommt gewöhnlich in tieferen Gewässern vor und wird mit Ringwaden oder Schleppnetzen gefangen. „Ich glaube aber nicht, dass es zwischen den beiden Vorfällen einen Zusammenhang gibt“, so die Biologin.

Diese Aussage begründete sie damit, dass die gefangenen Makrelen „sehr aktiv“ gewesen seien. „Gewöhnlich, wenn Fische wegen Sauerstoffmangel an Land gespült werden, sind sie fast tot und haben kaum noch Energie“, sagte sie. Daher: „Es kann sogar sein, dass die Makrelen von Afrikanischen Adlerfischen (Kabeljou) gejagt wurden und ins flache Wasser geflüchtet sind.“
