正三疣梭子蟹、日本对虾混养模式是沧州区域经多年养殖试验总结出的成功养殖模式,该模式充分利用了两种养殖对象的经济价值、生长特性。海螺(脉红螺)主要食物为双壳类,喜食杂鱼等动物尸体,把幼螺放入虾、蟹养殖池一起养殖,以虾、蟹类的残留饵料、死虾和池底自然生长的贝类等作为饵料。春季投入壳高2~3cm的海捕幼螺,到当年年底,壳高可长至7~8cm,体重150~250g。1试验材料与方法1.1材料来源 相似文献

潮间带围塘网箱鲍鱼海参混养技术 总被引：4，自引：0，他引：4
近年来，鲍鱼人工养殖迅速发展，其主要养殖方式有工厂化养殖、筏式养殖、海底底播 增殖和潮间带网箱养殖。前三种养殖方式不同程度存在成本高、风险性大、回捕率低的弊端 ，因而发展较慢。而潮间带网箱养殖具有成本低、风险小、回捕率高等优势。但这一养殖方 式仍存在着种类单一、物资器材利用率低、有效水体大部荒废等问题。根据这一情况，作者 依据鲍鱼、海参生活习性和特点，进行了鲍鱼、海参混养试验，发现在同一网箱内养殖以上 两个种类，既可以充分利用有效水体和养殖器材，又能促进生长，而且经济效益明显高于单 一鲍鱼养殖。通过两… 相似文献

文蛤具有迁移习性，滩涂围栏养殖管理不便。为此，进行了筏式吊养初步试验。5月开始投放壳长2．5—3．0cm文蛤苗种2500kg，至10月10日收获壳长4cm以上文蛤7200kg，平均每笼纯收人17．6元，文蛤长势良好。对影响存活率的因素以及放养密度、苗种选择进行了探讨。 相似文献

The effect of seawater adaptation on the survival of coastally released post‐smolt trout, Salmo trutta L., was investigated by release: (1) directly (with no adaptation); (2) after retention in net pens in the sea for 29–131 days (delayed release); (3) after feeding with a high‐salt diet (12–13.5% NaCl) for 4 weeks; and (4) after a combination of (2) and (3). In total, 17 640 trout (age = 1+, 1.5 and 2+ years; mean fork lengths = 18.2–25.6 cm) were released in 14 batches in the summer or autumn months of 1986–1989. All fish were of domesticated origin and Carlin tagged. Survival and instantaneous mortality rates (total and fishing mortality) were estimated from reported recaptures. Mortality rates were estimated for: (1) the post‐smolt period; (2) the period until the legal size of capture (40 cm) was attained; and (3) for larger sea‐trout. Release with a delay of 4 weeks gave an increased survival rate. A longer adaptation period did not increase survival. On average, survival was increased by 36%. Survival was not increased by high‐salt diets. Until attainment of the legal size for capture, survival was 9.6% higher on average, with extremes as low as 1.7% and as high as 38% in individual batches. 相似文献

The influence of oil-in-water nanoemulsion on the sensory, chemical, and microbiological qualities of sea bream and sea bass fillets stored at 2 ± 2°C was investigated. The results showed that the use of nanoemulsion extended the shelf life of fish one or two days when compared with the control. Treatment with nanoemulsion significantly (p < 0.05) decreased the values of chemical parameters throughout the storage period. Bacterial growth was inhibited by the use of nanoemulsion. Nanoemulsion had an inhibitory effect on protein denaturation during refrigerated storage and microwave cooking. Based on the results, it can be concluded that sunflower oil-based nanoemulsion extended the shelf life and improved the quality of both sea bream (Sparus aurata) and sea bass (Dicentrarchus labrax) fillets during storage. 相似文献

The Spanish aquaculture sector has undergone a rapid and continuous growth becoming one of the biggest European producers. A wide range of species are farmed and, among them, the sea bass, sea bream and turbot make a significant contribution to the total of the Spanish fish farming output. In this paper, we analyse and predict the medium-term trend of the production and price level for the three leading species previously mentioned. The results obtained show a significant increase in the production of sea bream, sea bass and turbot. The results show also a slight decrease in the sea bream average price, a stable trends for the sea bass and increasing prices for the turbot. 相似文献

通过对相同养殖环境条件下,青、白刺参(Apostichopus japonicus)体壁中营养成分(粗蛋白、粗脂肪、多糖、脂肪酸、氨基酸、微量元素等)的测定,比较两种剌参的营养品质与价值.结果显示,青、白刺参的出皮率,体壁中的水分、多糖和灰分含量差异显著(P＜0.05),粗蛋白和粗脂肪差异不显著(P＞0.05).青、白刺参体壁中均检测出20种主要脂肪酸,脂肪酸总量和多不饱和脂肪酸(PUFA)的含量差异不显著(P＞0.05),而青刺参饱和脂肪酸(SFA)含量显著高于白刺参,单不饱和脂肪酸(MUFA)含量显著低于白刺参(P＜0.05).MUFA中青刺参的花生四烯酸(AA)和二十二碳六烯酸(DHA)含量均显著低于白刺参(P＜0.05).青、白刺参体壁中检测出17种氨基酸,必需氨基酸(EAA)、鲜味氨基酸(FAA)和药效氨基酸(DAA)的含量均无显著差异(P＞0.05).青刺参体壁中天冬氨酸和精氨酸含量均显著低于白刺参(P＜0.05).青刺参体壁中Mn和Cr的含量显著低于白刺参(P＜0.05).重金属元素Pb、Cd、Hg、As的含量均符合相关食品卫生标准.综合评价认为,相同养殖环境条件下,白刺参的出皮率、多糖含量、脂肪酸中不饱和脂肪酸含量、AA和DHA的相对百分含量、氨基酸中天冬氨酸和精氨酸含量以及微量元素中Mn和Cr含量均优于青刺参. 相似文献
