New zealand turbot
The New Zealand turbot, Colistium nudipinnis, is a righteye flounder of the subfamily Rhombosoleinae in the family Pleuronectidae, found around New Zealand in shallow enclosed waters.
Their length is from 25 to 90 cm, and they are the largest flounder in New Zealand. The body of the turbot is broad, even a small oval and flat, and their oval body is broader and thicker than other flounders. The overall size is richer than other gums and has a pointed little nose. There are many small black spots on the deep olive-green body. Some spots are from dark green to black, the abdomen is somewhat grayish, and there is a circle outside. The turbot has a small amount of thorns on its surface, and its dorsal fin is hard and long, extending from the tip of the nose, with short rays and almost to the back. Both sides of the body are heavily scaled with small, and scales are deeply embedded in thick skin (73-86 along the side lines), scales on both sides cover lots of ventral surfaces. Its caudal fin is relatively small, similar in shape to the dorsal fin, and extends from the dorsal fin to the caudal fin at the same level as the dorsal fin. The weight of the turbot is between 0.2 and 0.7 kilograms. Young turbot usually matures into large fish within 4–5 years, while female fish are larger than males, and the total age of a lifetime is about 15 years old.
Natural global range: NZ Turbot from New Zealand.
Young turbots prefer small invertebrates and benthic animals, such as molluscs and shrimps, and large adult turbots will feed on smaller fish than other flounders. Like to prey during the day, the reaction speed is also very fast. It mainly feeds on fish and shellfish. Their mating period lasts for several months in the summer, and hundreds of females lay eggs. The number of reproductions in winter is significantly reduced.
