2. Incubation cobia fish eggs were round and slightly yellow, floating eggs, eggs of the fertilized eggs slightly water swelling, egg diameter 135 microns to 141 microns. Poor eggs are opaque and poorly buoyant and should be removed. The number of eggs per kilogram is about 500,000. When the water temperature is between 24Â°C and 26Â°C, the membrane can be hatched within 30 hours; when the water temperature is 28Â°C to 30Â°C, the membrane hatches within about 24 hours.
3. Larval larvae Newly hatched larvae are quite large in size compared to other marine fish. The overall length is about 3.5 mm. The body has melanin distribution. The oil globules are below the yolk sac and the fins are translucent. The fins are suspended at rest. In water, the abdomen faces upwards and is horizontal or inclined. At 12 hours after membrane rupture, the larvae were 4 mm in length and about 4.8 mm in length in 24 hours. The larvae were dark brown in color, with a silvery yellow color beginning from the back of the head to the tail. Occasionally, the larvae rushed for a short and anxious swim. , mainly suspended in water.
