The plaice, also known as the flounder, has a flat, grayish-black body with very fine scales and a white belly, and its most distinctive feature is that it has two eyes on the same side.
The flounder likes to hide in shallow and sandy seabed, sticking or burying its body in the sand, showing only its eyes and mouth, plus the color is very similar to the environment it lives in, so it is more difficult to find it. Flounders have only one dorsal spine that extends from the head to the caudal fin. They live mainly in temperate waters and have high nutritional value and few spines, making them a popular economic fish.
How to pick saucerfish:
When picking them, you should pick the ones with clear eyes and bright red gills, and the flesh should be firm and elastic, not flabby.
Look at the eyes. Good quality plaice have full, protruding eyes with clear, transparent corneas. Poor quality plaice have eyes that do not protrude, wrinkled corneas or bruises inside the eyes.
Look at the belly. A better quality plaice's abdomen is not swollen, and the anal hole is white and sunken.
