中文摘要 | 葉狀擬鬚蝦在臺灣是深海拖網的常見漁獲物,並具有頗高的經濟價值。但目前對其基本生物學特性之了解卻十分闕如,無法進一步的經營管理這一深海資源。本研究深入探討葉狀擬鬚蝦的卵巢發育狀況,從而有效判別不同卵巢發育期之母蝦,以作為日後對其資源管理及研究等之參考。根據卵巢之外部形態、顏色和細胞組織之變化,以及生殖腺成熟指數(GSI)之相互關聯,葉狀擬鬚蝦之卵巢發育可大致分為四個階段,而成熟的卵巢是呈黑色,並可清楚透過頭胸甲加以確認。另外精莢之附著(即交配)似乎是啟動卵巢發育的關鍵,而葉狀擬鬚蝦成熟卵細胞會相互擠壓並排列成緡錢狀,此現象為蝦類中僅見。 |
英文摘要 | Aristaeomorpha foliacea (Risso, 1826) is a commercially harvested deep-water shrimp in Taiwan. Considerable changes in the color and shape of the ovary occur during the maturation of this species. According to the relationships among the general appearance of the ovary, histology of ovarian tissues and gonadosomatic index, 4 distinct stages of ovarian development can be defined. The final stage, a ripe ovary is pale black and clearly visible through the carapace, and it can be a reliable guide for judging of stage of maturation. There is evidence that development of the ovary is induced by copulation. The arrangement of developing oocytes in a rouleau formation is unique for this species among shrimp. |
