摘要: 为了加快虎斑乌贼产业化养殖进程,于2017年6月9日至9月9日在浙江象山来发水产育苗场的室内水泥池进行了虎斑乌贼规模化养殖试验。共放养人工繁育的虎斑乌贼苗种2000只(平均胴长为3.8 cm),放养初始密度50~60只/m2,起捕前密度5~8只/m2;养殖条件:水位80~120 cm,水温20℃~32℃、盐度22‰~33‰、pH 7.6~8.4,溶氧4.0 mg/L以上;每天投喂冰鲜小杂鱼虾2次,投饵量6%~18%;日换水1次,换水量80%~100%。结果表明:经90 d养殖,乌贼的体质量随养殖时间呈指数增长:W=10.718e0.045d, 体质量为420~620 g,平均体质量为513 g;胴长随养殖时间呈线性增长:WL=0.1401d+3.1815,乌贼胴长达到15.3~18.6 cm,平均胴长为16.6 cm;养殖成活率达到61.5%,养殖平均饵料系数为4.36。表明虎斑乌贼是一种生长快、养殖周期短、经济效益高的养殖新品种,适合规模化养殖。

Abstract: In order to speed up the industrial breeding process of Sepia pharaonis, we carried out the experiment on the indoor breeding of Sepia pharaonis in the Lai Fa Aquatic nursery in Xiangshan from June 9 to September 9, 2017, with the following methods: First, a total of 2000 artificially bred Sepia pharaonis (with an average length of 3.8 cm) were stocked with the initial density of 50-60/m2 , and the precapture density of 5-8/m2. Second, the aquaculture conditions were maintained as: water level of 80-120 cm, the water temperature 20-32℃, salinity of 22‰-33‰, pH 7.6-8.4, DO≥4.0 mg/L. Last, ice fresh shrimp and small fish were feld two times every day, the feeding amount of 6%-18%; the water was changed once a day, with the water volume of 80%-100%. The results were as follows: after 3 months of breeding, the body weight of cuttlefish grows exponentially with the time of cultivation: W=10.718e0.045d, the body weight was 420-620 g, which the average body mass of 513 g. The body length of cuttlefish grew linearly with the culture time: WL=0.1401d+3.1815, the squid′s body length was 15.3-18.6 cm, with the average length of 16.6 cm. The survival rate of Sepia pharaonis was up to 61.5%, and the feed coefficient was 4.36. In summary: the Sepia pharaonis is a new kind of aquatic products with fast growth, short breeding cycle, low disease and high economic benefit, which is suitable for the large-scale cultivation and the prospects are very promising.
