Interesting about the plaice

  • The plaice or Pleuronectes platessa describes a species within the flatfish and is especially in Europe as a popular food fish.
  • Because of its orange-yellow dots on the upper side, the plaice is also known as the Goldbutt.
  • The plaice lives mainly in the cool waters of the North Sea and likes to live in depths of up to two hundred meters, so it is also often found far away from the Wadden Sea. Plaice also populate the Atlantic and some western parts of the Mediterranean.
  • As a flatfish, the plaice has a flat, between 20 and 50 inches long body, which is slightly oval shaped. The eyes are both on the right side of the head part, which points upwards. While the light to medium gray side of the eye has the characteristic points or spots, the blind or ventral side is colored white throughout.
  • Since the clod can adapt the eye side to the camouflage to the color of the seabed, the stains, if hidden in the sand, are often not visible.
  • There have been reports of specimens that are one meter long and weigh seven or eight kilograms, but this is a rarity.
  • The plaice lives exclusively on the ground, where it can bury itself during the day by strong fins blows in the dense sand, so that only the eyes are visible.
  • As a nocturnal predator, the plaice goes with the onset of darkness on the hunt for also living on the ground prey.
  • In the spring, the female fish release up to 50,000 eggs to the water, which are driven by the current into the Wadden Sea. After several weeks, the larvae hatch from the eggs as normally shaped fish with one eye on each side of the body.
  • At the age of about two months, the left eye gradually moves to the right side and the young plaice takes on the typical shape of the flatfish in the course of this metamorphosis.
  • The juvenile fish initially remain in the Wadden Sea, where they grow in sheltered conditions in shallow water. Only when the temperature gets too warm in summer do they gradually migrate to deeper zones. Only at the age of two, the babies finally swim into the open sea.
  • On the ground, the young clods are looking for lugworms and small crabs. Adult animals also feed on smaller fish, whitefish, crabs and shrimp.
  • The plaice is now led by the intensive fishing on the list of endangered species.
