低溫是降低甲殼類動物活動能力的常用操作方法,用以減少其在商業銷售過程中產生損傷,同時確保操作人員的安全。本研究探討不同低溫環境下,鋸緣青蟹 (Scylla serrata) 出現的麻醉反應及回復情形。試驗結果顯示,鋸緣青蟹急速曝露至水溫 12℃ 時,會開始出現麻醉現象,水溫越低麻醉所需時間越短,但回復活動力時間則無顯著差異。長時間曝露於低水溫環境時,回復時間會隨著溫度降低而拉長;在6℃ 水溫曝露60 min後,鋸緣青蟹會開始出現死亡現象,活存率降至 83.3%。於6℃ 低溫耐受性試驗回溫蓄養14 天後,曝露低溫時間達 60 與 120 min 組均出現死亡,活存率分別為 83.8% 與 66.7%。

摘要abstract(英)


Low temperature storage is currently a common method of reducing the activity of crustaceans to reduce their damage during commercial sales and to ensure the safety of operators. This study investigated the anesthetic response and recovery of mud crab (Scylla serrata) in different low temperature environments. The results indicated that the mud crab would be anesthetized at 12°C and the anesthesia time decreased with the water temperature decreased, but there was no significant difference in recovery time. Exposed to low water temperature for a long time, the recovery time increased with the temperature decreased. After 60 minutes exposed to 6 °C water temperature, the mud crabs began to die, and the survival rate dropped to 83.3%. After the low-temperature tolerance experiment at 6 °C, the mud crabs were reared at room temperature for 14 days, and deaths were found in two groups at 60 minutes and 120 minutes of exposure, and the survival rates were 83.8% and 66.7%, respectively.
