I have never seen a live furtail in northern aquariums. At present, we only know that on July 13, 2017, the Zhoushan Fisheries Research Institute of Zhejiang Province for the first time overcame a global problem: artificial breeding of hairtail was successful. In the institute's breeding base, more than 300 deep-sea fish have been living happily in the pond for more than two months.
The oilfish is a deep-sea fish. He has poor swimming ability. It floats in the middle layer of sea water during the day and sinks to the sea floor at night. When it is still, its head is upward and its body is vertical. It relies only on the movement of its dorsal and pectoral fins, and its eyes observe the movement above its head. If it detects prey, its dorsal fins will vibrate rapidly. his body will bend and he will lunge at the food. The tails ofhe hairtails have the particularity of lining up in groups when the water temperature rises each spring, the hairtails swim in groups towards the shore and migrate from south to north to reproduce. It's fishing season around the winter solstice, when the water temperature drops; , hair tails swim in the depths of the water to avoid the cold.
The hairtail fish belongs to the bony fish class Perciformes and the hairtail fish family in the vertebrate subphylum of the phylum Chordata. Also known as saury, chum, fat ribbon, oily ribbon, tooth ribbon, etc., they are fierce in nature. The body of the tail is flat like a strip on the sides and is silver-gray in color. The dorsal and pectoral fins are light gray with very small spots. The head of the tail is black. gradually narrows to the tail. The height is twice the lengthof the head and the total length is approximately 1 meter. It is fierce in nature and feeds mainly on shrimp and squid. Mainly distributed in the Western Pacific and Indian Ocean, it is distributed in the Yellow Sea, East China Sea, Bohai Sea and South China Sea. It is also known as the four seafoods of China, along with big yellow croaker, little yellow croaker and squid.
