  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 level (360 μatm),crabs were exposed for four weeks to projected oceanic CO2 levels (1200 and 2300 μatm,two weeks,respectively) before being subjected to a normal CO2 levels (390 μatm) for two weeks,i.e.,a recovery phase.During the whole experimental period,including recovery phase,stand metabolic rate (SMR),specific dynamic action (SDA) and feeding behaviors,were determined and observed at each experimental period,i.e.,initial normal CO2 level (360 μatm),high CO2 levels (1200 and 2300 μatm) and recovery CO2 level (360 μatm).

长毛明对虾曾经是中国东南沿海重要的养殖虾类之一,故其具有较高的经济价值.但由于对其野生资源的过度捕捞以及栖息地的环境破环等原因,长毛明对虾的野生资源量急剧下降,在2005年长毛明对虾已被作为濒临物种而被录入《中国物种红色名录》.为了增加对长毛明对虾种质资源的全面认识,且为该物种有效地保护和自然保护区的建立提供理论依据,本研究利用微卫星标记技术析研究我国野生长毛明对虾群体的遗传结构及其变异格局.本研
真虾下目Caridea隶属于节肢动物门、甲壳动物亚门、软甲纲、十足目、腹胚亚目。长臂虾科Palaemonidae种类众多,是真虾中经济价值较高的类群,罗氏沼虾Macrobrachium rosenbergii肉质鲜嫩,营养丰富,素有“淡水虾王”之称,是目前世界上养殖量最高的虾类之一;白虾属Exopalaemon也是重要的经济虾类,包括中国沿海的脊尾白虾Exopalamon carincauda和生
中华绒螯蟹(以下简称河蟹)是我国最重要养殖蟹类,近年来我国年养殖产量为80万吨左右,上市时间过分集中是困扰其产业健康发展的一个重要问题。本课题组在河蟹性腺发育生理和脂类营养方面具有良好的研究基础,自2010年底起启动了河蟹良种选育工作,以降低一龄性早熟率、培育二龄早熟(提前上市)和晚熟品系(推迟上市)为主要选育目标,至今已经选育到第三代(G3),在生产规模上取得了较好的应用效果,主要进展如下。
中华绒螯蟹(Eriocheir sinensis),俗称河蟹,是我国淡水中的主要水产养殖对象,为探索中华绒螯蟹(Eriocheir sinensis, Chinese mitten crab)肌肉生长抑制素基因(MSTN)的多态性及其与生长性状的相关性,研究以中华绒螯蟹群体(育种群体、大赛群体、野生群体)的DNA样本各20份为模板,采用直接测序法共获得了该基因的3个SNP位点,均位于第三外显子,分

中华绒螯蟹存在一龄性早熟二龄正常成熟的两种现象,尚不清楚其后代养殖性能是否存在差异.本研究利用构建的一龄早熟家系(One year precocious family)和二龄正常成熟家系(Two year normally mature family),评估了其子一代在成蟹养殖阶段的生长、存活率、产量、生殖蜕壳和性腺发育,结果显示:(1)两种河蟹在7-8月和11月的平均体重、甲壳长和甲壳宽均无显著
