可口革囊星虫(Phascolosoma esculenta)隶属星虫动物门、革囊星虫纲、革囊星虫属,俗称泥蒜、土笋、土钉等,广布于我国广西、广东、海南岛、福建和浙江沿海滩涂,为穴居泥沙型.我国多种药典中记载了可口革囊星虫食用和药用价值,其性寒、味甘、咸,具有滋阴降火、清肺补虚、活血强身及补肾养颜等功能.同时可口革囊星虫含有人体需要的多种氨基酸、微量元素和能够调节大脑功能的牛磺酸,具有增强机体免疫功能的作用.可口革囊星虫风味独特,有"海滩香肠"的美誉,深受国内外消费者青睐.福建著名的小吃"土笋冻"就是其加工而成的."山里有虫草,海里有星虫"体现了其极高的营养价值和药用价值.可口革囊星虫药用价值高、适温适盐范围广、抗逆性强、活动范围小,是发展增养殖的理想种类.

推广坛紫菜标准化养殖技术的核心示范区面积2000亩,养殖示范户56户,平均亩产比周边未实施标准化技术养殖户提高9.7％,效益明显.

紫菜产业是福建省"十三五"期间重点打造的十大特色品种产业之一.2018年7月,福建省水产技术推广总站成立的紫菜产业服务队在各设区市、县水产技术推广站的支持配合下,对全省紫菜的育苗、养殖、加工、品牌建设等情况进行了调研.

天下武功,唯快不破.钻井亦然,唯“快”取胜. 克深2-1-14井200天完钻,刷新当地钻井纪录; 克深242井162天完钻,提速达20％…… 5年时间,胡建不仅在新疆库车“山前”地区打出渤海钻探速度,还成了当地钻井的福星,甲方争着抢着要他去打井,员工美着乐着跟他打井. 是什么力量赋予他超凡本领,在世界顶级竞跑中,跑出“山前”加速度.

In the current study,we analyzed the aggregation pattern of Parapenaeus fissuroides Crosnier in sea area in the northeast of Fujian based on pattern intensity index of the negative binomial parameter,Morisita index,mean crowding,poly block index,and diffusion coefficient.We also discuss the factors that affect pattern intensity and ecological significance of the pattern intensity indices.The aim of the study was to explore new aspects in the protection of the fishery resources for P.fissuroides Crosnier.In spring,its population primarily consisted of twelve patches,which showed dispersed population distribution and the second smallest poly block index.The population in spring had the smallest mean crowding,the largest average distance between individuals,and the biggest diffusion coefficient compared to that in other seasons.In summer,the population mainly consisted of four patches with most concentrated population distribution.The biggest poly block index,biggest mean crowding,smallest average distance between individuals,and smallest diffusion coefficient were observed.In autumn,the population primarily consisted of five patches with moderately concentrated population distribution.The second largest poly block index and mean crowding as well as the second smallest average distance between the individual diffusion coefficient were explored.In winter,the population primarily consisted of fourteen patches with highly dispersed population distribution,the smallest poly block index,the second smallest mean crowding,and the second largest average distance between individuals and diffusion coefficient.The negative binomial parameter and Morisita index were employed to characterize the aggregation intensity.When the Morisita index is greater and the negative binomial parameter is smaller,the aggregation intensity is stronger,and vice versa.Mean crowding provided a more actual representation of the average individual crowding degree compared with the average density.Mean crowding reflected the average individual crowded degree.When mean crowding was large,the inter-specific competition was intense,and average distance between individuals was smallest.The poly block index revealed the constitution of the population patches.When the poly block index was big,the population primarily consisted of a few patches,and vice versa.The diffusion coefficient reflected the diffusion degree.The bigger the diffusion coefficient,the greater was the significant spread of the population.The food zooplankton was the major factor influencing the pattern intensity,and the inter-specific competition was the major factor mediating diffusion degree of the Parapenaeus fissuroides Crosnier in the sea area northeast of Fujian.In this study,the population distribution pattern intensity simplified the research of school behavior,which reflect the aggregation intensity,poly block,mean crowding,inter-specific competition degree,and diffusion degree to meet the school behavior inherent law.

长茎葡萄蕨藻(Caulerpa lentillipera),隶属绿藻门(Chlorophyta)、蕨藻科(Caulerpaceae)、蕨藻属(Caulerpa),因其色泽鲜绿,如一串串葡萄,被称为"海葡萄",又因其食用口感如鱼子酱,又有"绿色鱼子酱"之称.

当前我国大部分地区对虾养殖均采用高密度、高换水的传统池塘养殖和高位池养殖模式,存在单产低、效益差、生产不稳定等问题,有些地方滥用药物造成耗能、耗水、产品质量差等不良后果,水环境也受到不同程度污染,最终导致养殖生态环境破坏,进一步加剧病害发生,对养殖业构成灾难性威胁[1].因此,开发节水、节能、高产、环保的养殖模式是推动养殖业持续健康发展的有效途径.

2011至2012年霞浦县里沃深水潜网养殖专业合作社与霞浦县水产技术推广站利用在海岛乡浮鹰岛海区建设完成的30口升降式抗风浪大网箱进行大黄鱼和真鲷养殖试验，通过试验，拟摸索出一套大网箱养殖技术规程，养殖模式和养殖方法，分析存在问题，为今后湾外海区发展大网箱养殖积累经验，并起到示范和辐射带动作用，现将一年来的试验总结如下，供同行参考。
