| 建議與指正: | Spawns at surface over deep water, off-shore. Spawns for the first time at 2-3 years and in first half of December, when temperature falls below 7?C. Males aggregate at surface and females ready to spawn come from deeper water to join these aggregations. Eggs sink to bottom and hatch in March. Larvae swim to surface and start to feed after 8 days (Ref. 59043). | |||||||||||
