22. Jun: Since midsummer weekend...
Since midsummer weekend several reports about dead young herrings arrived from coasts along the German Bight. Hundreds of dead or weak young herrings were reported from Cuxhaven, Büsum, Eiderstedt peninsula and Nordstrand. As the water temperature is only 20° C at the moment an das herring usually avoid too warm waters by migration to deeper areas, the cause oft he phenomenon is unclear so far. Dead young fish should be reported and –if possible – a distintion should be made between herring and sprat (see determination key).
