臺灣的鳳螺養殖產業發展評估

Abstract

鳳螺(Babylonia spp.)肉質鮮美、經濟價值高，在亞洲地區十分受到歡迎。近年來由於天然資源漸趨匱乏，鳳螺市場供不應求，養殖鳳螺已成大勢所趨。臺灣九孔(Holiotis diversicolor)養殖業自從發生大規模病變後，產量大幅下降，至今仍無好轉，連帶產生許多閒置的養殖空間，極需替代的養殖物種。鳳螺具有生長快、存活率高、適合高密度養殖、產品價值高等優點或可取代九孔成為新興養殖物種。由於目前臺灣的鳳螺養殖仍未普及，在養殖方式及管理上的研究仍然缺乏，因此本文主要介紹鳳螺的基本生物學特性及養殖進展，並針對鳳螺養殖的未來發展，及鳳螺替代九孔產業的可行性進行分析比較。Ivory shells (Babylonia spp.) are the economic important marine gastropods in Indo-Pacific area. The market price and demand of Ivory shell are continued soaring due to the decreasing of natural stocks exploited from various traditional fishing areas. On the other hand, it deadly needs to find a solution to the problem of plenty free small abalone (Haliotis diversicolor) aquaculture spaces in Taiwan. Aquaculture of Ivory shell may be a feasible solution. In this review, we introduce the basic biology of Ivory shells , update the aquaculture conditions, and analyze the development potential of ivory shell industry in Taiwan.
