Windmolens stimuleren kabeljauw populatie

AMSTERDAM – Belgische wetenschappers denken dat windmolens een belangrijke rol kunnen spelen bij de groei van kabeljauw in de Noordzee.

De onder druk staande kabeljauwpopulatie zou hierdoor wel eens een grote stimulans kunnen krijgen.

Jonge kabeljauw komt bijna niet voor in het Belgische deel van de Noordzee, maar een onderzoeker van de Universiteit van Gent ontdekte aan de voet van een windmolen in de Thorntonbank pas geboren kabeljauw.

Kraamkamerfunctie

“Dit wijst erop dat de ‘beschermde’ omgeving van de windmolens, waar niet gevist mag worden, een kraamkamerfunctie kan vervullen”, aldus de onderzoekers.

In 2008 werd begonnen met de bouw van het windpark op de Thorntonbank. Er staan 54 windturbines op de rol die tegen de 300 megawatt opgeteld vermogen hebben.  De laatste fase, de bouw van 24 turbines, zal tussen 2012 en 2013 worden afgemaakt.

Andere vissoorten

Al na een jaar werden er al 30.000 steenbolken, een kleine kabeljauwsoort, gevonden bij de windmolens. Hierna kwamen ook andere vissoorten tevoorschijn zoals tongschar, zeebarbeel en pladijs gevonden.

De kabeljauwpopulatie staat al jaren historisch laag, maar is wel belangrijk voor de visserij. De huidige vondst kan dus een uitstekende opsteker zijn.

    These three figures — William Rick Singer, Mark Riddell and Rudolph Meredith, respectively — are at the center of the nationwide scandal in which 33 parents are accused of using their wealth and means to help their children game the college admissions system.
    But those three names do not appear anywhere in the complaint text, though the document gives enough clues to make clear who is who. Instead, they are named as Cooperating Witness 1, 2 and 3, and each agreed to plead guilty and to cooperate with the government in the hope of obtaining leniency when they are sentenced, the complaint says.

    Trump was surrounded at Friday’s event by officials from Customs and Border Protection as well as surviving family members of those who have loved ones killed by undocumented immigrants. Attorney General William Barr was also at the President’s veto event.
    While some lawmakers including some Republicans — have argued against the President’s use of national emergency powers in this instance, the Justice Department set forth a robust defense of the President’s authority to do so in a letter to Senate Majority Leader Mitch McConnell earlier this month, according to a copy obtained by CNN on Friday.
    “The President acted well within his discretion in declaring a national emergency concerning the southern border,” wrote Assistant Attorney General Stephen Boyd, setting out the legal basis for the proclamation under the National Emergencies Act and additional statutory authorities, which largely tracks an internal memo issued by the Office of Legal Counsel at the Justice Department.

    Christina was born in the royal castle Tre Kronor on 18 December S. 8 December] 1626. Her parents were the Swedish king Gustavus Adolphus and his German wife, Maria Eleonora, had already had two daughters—a stillborn princess in 1620, and then the first Princess Christina, who was born in 1623 and died the following year.3] Excited expectation surrounded Maria Eleonora’s third pregnancy in 1626. When the baby was born, it was first thought to be a boy as it was “hairy” and screamed “with a strong, hoarse voice.”she later wrote in her autobiography that, “Deep embarrassment spread among the women when they discovered their mistake.” The king, though, was very happy, stating, “She’ll be clever, she has made fools of us all!”6] From most accounts, Gustav Adolf appears to have been closely attached to his daughter, and she appears to have admired him greatly.
