Oviform (Trachinotus ovatus) Local names are gold, é²³, red three yellow wax é²³, genus, 鲈-shaped head, ? 科, é²³ é²³ 属 genus, warm water, tender meat, delicious taste. Oviform (Trachinotus ovatus) (Linnaeus), commonly known as golden pheasant, yellow lamellae, is a bony fish skeleton, vertebrate phylum, bony fish, oyster-shaped head, genus, genus and genus. The oval body is flat, oval, large in size, fast growing, and strong in disease resistance; it is a warm water pelagic fish, the living water temperature range is 14~32 °C, the optimum water temperature is 24~28 °C; the salinity is 5 Between ‰ ~ 32 å‡å¯ can be farmed, 15 ‰ grow faster. In the natural waters, there are oval-shaped pods and grasshoppers, and they are foraging for food, fighting for fierce food, and they mainly feed on small molluscs and small snails. Large individuals have 5-10kg, tender meat, delicious taste, is a valuable food fish. Oval? The division of the early stages of development With regard to the division of the early stages of fish development, the early stage of development of ovum pods was divided into larval stage, juvenile stage and juvenile stage according to the development characteristics of the yolk sac, oil globules, and bending fins and scales of the caudal vertebra. (1), larvae are divided into yolk sac larvae, vertebral caudal larvae, tail vertebral bent larvae, tail vertebral larvae after bending. (2) On the 18th day, the fins were developed and scales appeared. They began to enter the juvenile period. (3) Juvenile period: On 22nd day, the fish body covered silver scales and its body color was silver. The shape was similar to adult fish. Early developmental characteristics According to the observation of this experiment, after the oval-shaped puffer developed into juvenile stage, the fins of the dorsal and anal fins have the development of melanin, pigment and fins as in the case of Blatsella pilosullatus and larvae. At the time of hatching, it has a point-like melanin pigment. When the body was newly hatched, there were a lot of black markings on the trunk. In the 1st to 4th day of larvae, the melanin pigment gradually deepened to form a melanin band; at the age of 5 days, silver pigment appeared on the head of the larvae. At the age of 7 days, the body color of the larvae was mostly reddish-brown, and at this time, part of the larvae became full body color after becoming full, and most body color of larvae became silvery at the age of 12 days. Risk during early development The yolk sac of the newly hatched larvae is very large, and the yolk sac of the newly hatched larvae is very large. The consumption of yolk material is very fast after the hatching. The food is started on the third day, the rotifers are eaten at the beginning of the day, the yolk sac is completely absorbed at the age of 4 days, and the oil balls of the larvae at 7 days disappear. When larvae start to consume artificial feed with squid powder at 10 days of age, the larvae will not be able to complete feeding due to changes in feed and palatability. Therefore, the larvae will die, and they should be mixed and fed together with biological feed and salmon powder during the initial domestication. When the larvae are adapted to the salmon meal, they are completely fed with feed, which can effectively increase the survival rate of the larvae.
