螃蟹

摘要： "一入高淳蟹满席,一口米酒唇留香"。被誉为"江南圣地、鱼米之乡"的高淳,是我国河蟹养殖六大原产地之一,产出的固城湖螃蟹青背白肚、金爪黄毛,肉质细嫩、味道鲜美。近年来,江苏省南京市高淳区以入选全国农村综合性改革试点试验区为契机,围绕生态养殖、品牌强化、设施升级等方面持续提升产业水平,加快推进螃蟹全产业链发展。

摘要： 立冬了,我们这些馋虫蠢蠢欲动。立冬就要“补”,大补才能过严冬啊。一大早,我和哥哥就准备赶去菜市场买螃蟹。但他临时有事,就从包里抽出两张一百元的人民币塞给我,让我自个儿去买。我直奔菜市场,随便找了一个螃蟹摊儿。那摊贩非常热情地说:“好嘞,我帮你挑,包你满意!”只见他麻利地拿起几只张牙舞爪的大螃蟹丢进袋子里,接着扎袋,称重,报价:“一共146元!”我将早已准备好的200元钱递给他,他找钱给我,笑着嘱我走好。

摘要： 今大,外公送来一只大螃蟹,我开心得不得了,因为我又可以美美地大吃一顿啦!在妈妈处理螃蟹前,我先小心翼翼地把螃蟹放在了地上它穿着一身坚硬的灰绿色铠甲,像一位威武的勇士。那对大大的钳子让它看上去威猛无比。

摘要： 苏轼有诗盛赞大闸蟹:“不到庐山辜负目,不食螃蟹辜负腹。”今天我就带大家来吃苏州最著名的阳澄湖大闸蟹。阳澄湖大闸蟹的特征可以用八个字来概括——“青背、白肚、黄毛、金爪”。这可是其他地方的螃蟹模仿不来的。我对照着这八个字,仔细观察妈妈买回来的阳澄湖大闸蟹,确实是这样。

摘要： 为了调查福建省市售螃蟹中镉的污染情况,反映所在养殖区域重金属镉污染状况,及时发现重金属镉安全隐患提供数据,2018-2020年在福建省10个地区采集8种共496份螃蟹样品,依据GB 5009.15-2014《食品安全国家标准食品中镉的测定》中的石墨炉原子吸收光谱法测定螃蟹中镉含量。并利用单因子污染指数评价不同年份螃蟹中镉的污染程度。结果显示,2018-2020年的496份螃蟹样品中,3年整体镉含量平均值为(0.447±0.646)mg/kg,镉含量范围为(0.003-6.2)mg/kg,检出率100%,超标率为21.98%;福州地区2018-2020年期间,螃蟹中的镉含量呈下降趋势;其它地区螃蟹中镉含量2020年明显低于2019年,差异具有明显统计学意义(P<0.001);螃蟹中的镉平均含量受时间、地域及种类的影响下存在较大的差异。其中中华绒螯蟹类中镉含量最低,超标率仅为0.67%,面包蟹和花蟹中镉平均含量分别为(0.986±0.810)mg/kg和(0.704±1.17)mg/kg;超标率分别为59.09%、23.08%。与中华绒螯蟹类中镉含量对比,有明显的统计学意义(P<0.001)。结果表明,螃蟹对重金属镉的富集能力较强,螃蟹中镉平均含量受到时间、地域及螃蟹种类影响;福建省2018年到2020年螃蟹中镉污染水平明显有改善,但部分地区仍然存在镉污染情况,存在一定的安全隐患,应合理适量食用螃蟹,注重食用螃蟹的种类及时间。并要加强其饲养水域的污染防治工作。

摘要： 去年暑假,我被大人们“骗”到乡下,去做了一件很“疯狂”的事。阳光媚的早上,我被爸爸叫醒,迷迷糊糊才睁开眼,便听见大人们在说要回乡下。我一想:乡下多好呀,可以到处跑,上树掏鸟窝,下河摸螃蟹,唯一美中不足的是天太热了,乡下又没有空调。但没关系,鸟窝、螃蟹已经战胜了一切。我便乐呵呵地跟着他们回乡下了。

摘要： 洪泽,因水而生,以湖而名,依湖而兴。在这里,奔腾千里的滔滔淮河曾与九曲黄河交汇合流,汇聚成洪泽湖;在这里,绵延千载、日出斗金的洪泽湖水孕育出久负盛名的水中贵族--洪泽湖螃蟹。洪泽湖盛产大闸蟹,至今已有1400多年的历史。据记载,隋炀帝开辟运河,除了到扬州看琼花,另外就是品尝洪泽湖大闸蟹。明朝时“洪泽湖螃蟹”就是朝廷的贡品。相传明太祖朱元璋幼时就非常喜食“洪泽湖螃蟹”,常与小伙伴下湖捉蟹解馋,后来入主京城,每至中秋、重阳,淮安府官员必挑选极品大蟹进京进贡,一时京城王公贵族啖蟹之风盛行,“洪泽湖螃蟹”名噪一时。

摘要： 滦南海蟹,国家地理标志证明商标,河北省唐山市滦南县的特产。“滦南海蟹”又名黄螃蟹,生长于浅海,肉嫩黄肥,鲜美可口,有养筋益气、理胃消食,散诸热,通经络等药用功效。“滦南海蟹”为肢体动物,巨螯尖甲,青色,横着爬行。其肉嫩黄肥,鲜美可口,有养筋益气、理胃消食,散诸热,通经络等药用功效。而且营养及其丰富,每100克蟹肉可含蛋白质14克,脂肪2.5~5.6克,碳水化合物7.4克。

摘要： 最近,饲养角里来了新伙伴--4只螃蟹。那是“水产大户”帅帅的爸爸带给孩子们的礼物,还带来了一只大盆、水泵、网兜。这一天,几个好伙伴过来围观,刚一蹲下,4只螃蟹就没命似的在盆里跑起来。“它们在逃跑,怕我们抓住它。”“那只大的跑得最快。”“不对,这只小的跑得快。”“肯定是公螃蟹跑得快。”“它们跑的方向不一样,好像在赛跑。”“可赛跑是要有跑道的。”……幼儿的谈话真实地反映出他们对周围世界的认识,既然孩子们都关注起“螃蟹赛跑”的话题,也激发起了他们的好奇心,教师该如何捕捉这种可能性进行一次由孩子们引领的课程之旅呢?

摘要： 采用随机采样法在若干市场采集3种螃蟹,共43份样品,利用电感耦合等离子体质谱法测定螃蟹不同可食用部位的镉含量.结果43份样品中,镉检出率为100%.3种螃蟹蟹膏/蟹黄中的镉含量均大于蟹肉中镉含量,蟹体镉含量情况为面包蟹>梭子蟹>大闸蟹,差异具有统计学意义(P<0.05).梭子蟹和面包蟹中镉含量超标,在摄入时需注意摄入量,镉主要集中在蟹膏/蟹黄部位,与螃蟹品种无关.

摘要： 对8个采取不同增氧方法螃蟹养殖池塘检测水温、pH、溶解氧、氨氮、亚硝酸盐、异养菌总数及弧菌总数。结果发现不同的增氧方式对螃蟹养殖池塘的水温、pH值无显著影响;未采取任何增氧措施的螃蟹养殖塘在后半夜养殖水体中的溶解氧含量显著下降(p<0．05)。采取底层管道增氧系统微孔管道，间距在10-12 m的增氧效果较好，溶解氧含量在整个养殖期间保持较高水平;养殖水体中氨氮、亚硝酸盐含量在养殖中后期均有所增加，但增氧效果较好的3个螃蟹养殖塘氨氮、亚硝酸盐变化不大7、8月份的异养菌总数显著高于6月份(P<0．05)，弧菌数则为7、8月份显著低于6月份(P<0．05)。总体来看，间距12 m的宜兴高塍镇自制的微孔管道系统增氧效果好，能改善螃蟹养殖池塘水质，且经济实用，成本不高，是一种有效实用的新型增氧方法。

摘要： 有研究资料表明,气象条件对螃蟹产量的影响很大,并且有一定的规律性.本文主要从舟山市独特的海洋性气候着手,统计分析了1997~2002年的螃蟹产量的年际变化,并着重对4~5月和6~8月的气象因子对螃蟹的影响进行了探讨.通过分析发现,日照、气温、降水等气象因子和螃蟹的成长、发育、繁殖都有着紧密的联系,特别是在两个不同的重要时间段里,气象因素对其有着不同的影响,且由于气象因素的影响导致舟山市螃蟹产量年际起伏较大,有一些规律可寻.

摘要： 近年来,以螃蟹为主的水产养殖已成为我国部分地区农村经济结构中的一种主要经济元素.螃蟹又名河蟹,生长周期一般有四个阶段,即在海水中卵孵化成蚤状幼体,咸淡水中成大眼幼体和仔蟹,仔蟹在淡水池塘中培育成一龄幼蟹,一龄幼蟹再放入大塘和湖泊中养殖,最后成为成熟的螃蟹(绿蟹).从一龄幼蟹到成熟的绿蟹养殖,称之成蟹养殖.而成蟹养殖和生长与气象条件有着密不可分的关系,气象条件的变化会直接影响到螃蟹的蜕壳生长和死亡.本文通过在国家生态县,国家著名品牌“固城湖”螃蟹养殖区,安装自动气象站的方法,对成蟹养殖生长中与温度、日照、降水主要气象要素关系的观测和分析研究,依据主要气象要素温度、日照、降水发生变化,给螃蟹生长带来的影响,从而确定成蟹养殖生长中温度、日照、降水主要气象要素利弊的指标范围.成蟹养殖生长中,不同季节,关键时刻对温度、日照和降水的要求各不相同,特大暴雨和干旱,成蟹生长前期和后期的低温寡照,长时间的高温和连阴雨,都会阻碍螃蟹的正常生长,甚至死亡.不过,在养殖过程中,运用科学的养殖技术,结合气象预报服务,调节好成蟹养殖生长中的环境因子,可减少或降低温度、日照、降水等气象要素的变化对螃蟹蜕壳生长的影响,达到螃蟹顺利生长的目的.

摘要： The genus Scylla, recently divided into four separate species: S. paramamosain, S. serrata, S. tranquebarica and S. olivacea, is a set of large and primarily carnivorous portunid crabs. Morphological approaches are difficult to identify the four species from each other unambiguously, especially in those cases where morphological features are missing or misleading. DNA barcoding has been considered to be an effective standardized tool for identification of animal species within a known taxonomic framework. In the present study, we examined the utility of COI sequences as DNA barcoding for effective identification of four species of genus Scylla. The average intraspecific K2P distances were 0.40% in S. paramamosain, 1.4% in S. serrata, 1.5% in S. olivacea and 0.6% in S. tranquebarica, respectively. The interspecific K2P distances were much higher than the intraspecific distances, and the maximum interspecific distance（19.8%）was between S. paramamosain and S. olivacea, while the minimum interspecific distance（9.2%）was between S. paramamosain and S. tranquebarica. No overlaps were detected present between intraspecific and interspecific distances of four species, suggesting the existence of distinct barcoding gaps. The neighbour-joining（NJ）tree consisted of four distinct clusters, with all sequences of each species forming a strong monophyletic cluster. Furthermore, we developed a PCR-based species identification method that could identify the four species of genus Scylla rapidly and effectively. This paper provided two methods including DNA barcoding and PCR-based protocols for species identification of genus Scylla, that will be useful for linking different developmental stages and hybridization breeding program of genus Scylla.

摘要： The mud crab Scylla paramamosain plays a significant role in fishery resources in China. In this study, we developed 18 polymorphic microsatellite markers in this important crab by 5’ anchored PCR technique. A total of 125 alleles were detected in a single population of 32 individuals of S. paramamosain. The number of alleles per locus ranged from five to nine, with the allele size ranging from 166 bp to 316 bp. The polymorphism information content（PIC), observed and expected heterozygosity ranged from 0.39 to 0.88, from 0.33 to 0.92 and from 0.42 to 0.86, respectively. Three loci（Scypa13, Scypa14 and Scypa15）deviated significantly from Hardy-Weinberg equilibrium（HWE）after Bonferroni correction（P<0.0028), and no linkage disequilibrium was found between loci pairs. These polymorphic microsatellite markers will be useful for the study of population genetic structure, construction of genetic linkage maps and mapping of economically quantitative trait loci（QTL）in S. paramamosain.
