Tributyltin(TBT) and cadmium (Cd) are two common pollutants in aquatic environments.This study was designed to examine the physiological responses of juvenile Grass Crap Ctenopharyngodon idella to TBT
Currently,the spotted scat (Scatophagus argus) has been one of the most important species in South Chinaas a new resource for marine aquaculture from economic perspective.Despite the importance of thi
Intestinal microbial communities play a central role in nutrient and energy cycling of host.The swimming crab has a close symbiotic association with its gut microbiota.However,basic information on int
Perennially in cold,Antarctic fish gradually formed a series of cold resistance mechanism of antifreeze.To identify the antifreeze mechanism of Antarctic fish,ZF4 cells were cultured under 18℃ for col
The effects of simulated future ocean acidification on feeding behaviors and energy metabolism of the brown crab Cancer pagurus were examined.Following seven weeks of pre-acclimation to normal CO2 lev
Cyprinid herpesvirus Ⅱ (CyHV-2) is the main pathogen causinghaematopoietic necrosis disease in Carassiusauratusgibelio.Although many nucleic acid-based diagnostic methods have been applied,no stable a
对常规巴氏灭菌后即食整肢小龙虾(采用铝箔袋真空包装)的特定腐败菌(specific spoilage organism,SSO)进行了鉴定.采用传统分离纯化、菌落外形观察及细菌形态学镜检的方法,并结合16S rRNA分子生物学手段和限制性内切酶消化分析,结果共从样品中分离到82株典型菌,其中优势菌为苏云金芽孢杆菌(70株,占85.37%)和粘质沙雷氏菌(7株,占8.54%).本文首次分析了即食小龙
本文旨在通过对养殖池塘中中华绒螯蟹体内多环芳烃(Polycyclic Aromatic Hydrocarbons)含量的研究,进而对食用中华绒螯蟹对人体健康的潜在风险进行分析.实验采用气相色谱-质谱(GC-MS)连用的分析化学方法对中华绒螯蟹中16种PAHs进行定量分析,结合美国国家科学院和国家研究委员会通过的健康风险评价方法进行中华绒螯蟹中PAHs的食用健康风险评价研究.结果 表明中华绒螯蟹中1
本研究主要探讨了两种环境因子——光照和温度以及厚壳贻贝密度对厚壳贻贝群居性产生的影响。本实验通过在不同环境条件下对厚壳贻贝稚贝群居性进行对照实验,记录不同时间稚贝的聚堆率,从而验证光照、温度和密度对厚壳贻贝稚贝群居性的影响。实验结果表明,厚壳贻贝的密度对其群居性具有极显著影响,而且密度越高,稚贝的聚堆率越高,其群居性越强;光照对厚壳贻贝稚贝的群居性也有极显著影响,而且,光照越高,稚贝的聚堆率越低,
克氏原螯虾(Procambarus clarkii)俗称淡水小龙虾,是具有重要经济价值的淡水虾类.然而,随着养殖密度的增加,小龙虾不仅普遍出现性早熟的现象,导致克氏原螯虾成虾规格小,长不大,市场价格低,而且性早熟的虾抗逆能力差,一旦有病原物的侵染,或环境变化,很容易死亡,给克氏原螯虾养殖业带来重大经济损失.本研究采用全长均一化差减杂交(FNSH)技术,在性早熟和正常生长的克氏原鳌虾卵巢中鉴定出16
