虎斑烏賊Sepiapharaonis具高食物轉換率、成長快速及短的生命週期,擬建立量產 養殖及放流相關技術,成為發展潛力之海水養殖新興物種。虎斑烏賊於2015年11月 28日~2016年1月12日共產卵31次,產卵數介於20~696個,總產卵數為8,058個卵。 並進行初期餌料試驗,以五鬚蝦組、五鬚蝦+豐年蝦組、前7天豐年蝦+五鬚蝦組及豐 年蝦組(4處理2重複)經20天培育後,試驗結果虎斑烏賊在低水溫(17.75±1.55℃)下 ,初期餌料試驗結果以五鬚蝦組+豐年蝦組平均活存率為92%最佳與其他組有差異 (P<0.05),接著為前7天投餵豐年蝦+後13天投餵五鬚蝦組平均活存率為80%與豐年蝦 組有差異,再接著為五鬚蝦組平均活存率為78.5%與豐年蝦組平均活存率為74.5%兩 組無差異。在平均胴長方面以五鬚蝦組+豐年蝦組11.28±0.43mm,接著為前7天投餵 豐年蝦+後13天投餵五鬚蝦組10.97±0.74mm,再來五鬚蝦組10.62±0.62mm,最後為豐 年蝦組為10.28±0.08mm四組無差異。在平均重量方面以五鬚蝦組+豐年蝦組 0.35±0.01g與前7天投豐年蝦+後13天投餵五鬚蝦組0.34±0.62mm最好與其他兩組有差 異,接著為豐年蝦組0.27±0.62mm,五鬚蝦組0.26±0.05g最差。 國內有關虎斑烏賊的相關研究甚少,可供參考之文獻資料均極度欠缺。本研究雖對 虎斑烏賊產卵、幼生飼育及養成做了一些探討,從孵化後養殖8個月即可上市販售 ,相當具有養殖潛力。野生種魚在人為環境下經馴養後自然交配產卵成功,受精卵 孵化後經仔稚魚培育及人工養成,約8個月培育可成熟產卵,今年培育出15000尾人 工幼魚全長2-3cm,分2次實施放流,第1次105年1月21日放流8000隻,於105年5月 8日第2次放流7000隻增裕海洋資源;並可發展養殖產業及休閒漁業,增加漁民收益 。

研究報告摘要(英)


Cuttlefish Sepia pharaonis, with foods a highconversion rate, rapid growth and short life cycle, In order to establishproduction and releasing technologies become to seawater aquaculturedevelopment potential candidate. All 20 cuttlefish total weight of 30.91 kg of 14 male and 6 female fish, wasto be stocked at 15 tons indoor cement pond. Female fish spawned from November28, 2015 to January 12 2016. Total spawning time 31 times, the number of egg s laidrange from 20 to 696 eggs, with a total number of 8,058 of eggs. Then theinitial field trials to 4 group with A group: shrimp Exopalaemon orientis larvae, B group: shrimp Exopalaemon orientis larvae + Artemia salina, Cgroup: initial Artemia salina for 7days + shrimp larvae Exopalaemon orientis for 8- 20days and D group: Artemiasalina as 4 group to juvenile cuttlefish after 20 days rearing. The results werethat cuttlefish mean survival rate was to feed B group 92% was the best, following C group 80%, A group 78.5% and D group 74.5% was the worst respectively. On theother hand cuttlefish mean mantle length of 4 group were all the same and bodyweight to feeding both B group (weight0. 35±0.01g), and C group (weight0. 34±0.01g) jveniles were the best,following D group (weight 0.27±0.05g) and A group (weight0. 26±0.02g) were the worst respectively.
