中文摘要 | 本試驗的目的是要研究將白蝦(Penaeus vannamei)長期養在密閑式循環過濾系統 中,它們的成長與生殖是否會受到抑制,以評估利用密閉式循環過濾系統培育白蝦種蝦 的可行性。在密閉式循環過濾系統中經過11個月的培育後,第11期的期幼虫成長為平 均體重33.9公克的雌蝦與26.5公克的雄蝦,活存率為29.6%。所有雄蝦皆已具有精筴。 將所有的雌蝦切除一支眼柄,以促進卵巢的成熟。眼柄切除後第10天開始有雌蝦產卵, 前後11天共43.9%有的雌蝦第一次產卵。交配成功率為38.9%。平均每次產卵量為 119,000粒,最少為53,000粒,最多為163,000粒。平均孵化率為71.0%。試驗結果顯示 在密閉式循環過濾系統培育白蝦種蝦的可行性是很高的。 |
英文摘要 | The purpose of current report is to study whether growth and reproduction of Penaeus vannamei will be inhibited being cultured in the closed recirculating system for long time to estimate the feasibility of culturing breeders of the animals in closed system. Juvenile PL �V Penaeus vannamei had been cultured for 11 months in the closed recirculating system, and grew to a average weigh 33.9 and 26.5 g of gemale and male individually. The survival rate was 29.6%. All the males had presented spermatophores. All the females were ablated eyestalk to induce maturation. The shortest latency period between eyestalk ablation and spawning was 10 days. During 11 days, 18 newspawners were obtained. Percentage of successful mating spawners was 38.9%. Eggs per spawn was 119,000 on average and ranged from 53,000 to 163,000. Mean hatching rate was 71.0%. The results showed it was possible to produce the breeders in a closed system. |
