In order to avoid the low sea temperature of Penghu during the winter and to reduce the grow-out period of cobia in the marine sea cage, the farmer should stock 500g-1Kg overwinter juvenile cobia in April. Most of the overwinter cobia were from the earth pond in Taiwan. When harvesting, farmer had better add KMnO4 or H2O2 in the collection fish area to oxidize the sulfide. Due to the higher risk of culturing overwinter juvenile cobia, farmer must pay more attention to manage the whole operating procedure. This investigation showed disease management of cobia was the key point of the step-wise culture. In December, farmer could selectively harvest the cobia which were about 5-9 Kg. |
