孔雀绿除杀对虾幼体聚缩虫的研究

采用孔雀绿（C23H25n2Cl）除杀斑节对虾（PEnAEuSMOnOdOn）仔虾期幼体附生的聚缩虫（zOOTHAnnIuM）的实验结果表明，育苗过程302~306k温度条件下，0.6~0.8PPM（相当于1.64x10-6~2.19x10-6MOl/l）药物浓度作用时间6~8H，可达到除杀聚缩虫又不伤害仔虾幼体的良好效果.育苗池中的有机质会降低除杀聚缩虫的药效，当有机质含量较高时，宜采用上述浓度范围的上限

Advances in genetics and breeding in abalone: a review

Abalones are important farming species with a high economic value. They have already been farmed for more than 50 years. As problems and new requirements rose continuously in culture industry of abalone, studies on genetic and breeding techniques are needed to improve characteristics and to gain new traits. This review concentrates on advances in genetics and breeding techniques in abalone.As for genetic studies, karyological analyses, allozyme, DNA markers and genetic diversity were reviewed. So far, karyological analyses in abalone have been performed in 12 species that can be divided into three groups according to the chromosome number. In some economically important species, loci of allozymes and microsatellites have been isolated and applied to investigate the genetic structure of natural and hatchery populations and to identify the result of chromosome set manipulation, but the related reports are only a few yet. The resultsof investigation with DNA markers and allozymes showed that the genetic structure of natural populations presents two characteristics: excessive homozygosity and subdivision.Advances of various breeding techniques, including introduction, selection, hybridization, polyploidy, gynogenesis and gene manipulation, were reviewed in the other part.Although Haliotis discus discus, introduced from Japan, has become one of the most important culture species in China, the economic, social and environmental effects of introduction have been rarely studied. Selection is one of the most important and basic breeding techniques, but the studies on selection are only a few and preliminary, referring to the relations between genetic characteristics and the traits of growth and resistance, genetic diversity and heritability of quantitative traits, and the effect of selection. Interspecific hybridization was the first breeding program carried out in abalone.Experimental hybridization have been carried out for about 20 crosses. Heterosis, such as faster growth and high survival rate, has been observed in some crosses. Triploids have been successfully induced in many species of abalone with physical or chemical shock, e.g. H. discus hannai, H. rufescens, H.diversicolor diversicolor and H. midae.Field experiments were conducted in some species of triploid abalone. In comparison with triploid, the research on tetraploid is still in quest stage. The progress of induction of gynogenesis in abalone is quite slow. Conditions of sperm inactivation,diploid restoration and nuclear behavior of gynogenetically activated eggs have been researched on in H. discus hannai. Notwithstanding the gene transfer technology in abalone is in the quest stage, the research have already involved preparation of exogenic DNA, means of gene transfer, identification integration and expression of target gene,etc. Three research directions in these topics were proposed: to investigate the germplasm resources of abalone deeply and widely, to make use of traditional breeding methods and modern biotechnique synthetically, and to combine the science research with production practice.国家863课题(2001AA621080

The contents and dynamics of different forms of phosphorus in shrimp culture area of Pantu, Tong'an Bay, Xiamen

１９９６年５至１９９７年２月对厦门市同安湾潘涂垦区两口虾池及进水渠道不同形态磷的含量与动态进行了 调查。结果显示，虾池的颗粒磷（ＰＰ）含量明显高于邻近内湾，可溶性有机磷（ＤＯＰ）含量略高于内湾，可溶性无 机磷酸盐（ＤＩＰ）含量则明显比邻近内湾的低。虾池中的磷主要以ＰＰ形态存在（７８．２５％），ＤＯＰ、ＤＩＰ含 量较少（ｌ．８２％和６．９３％）；垦区内湾则是以ＰＰ和ＤＩＰ为主（４４．４９％和４６，３９％），ＤＯＰ所占比例最小 （９．１２％）。虾池与垦区内湾不同形态磷的季节变化也存在一定差异。From May 1996 to Feb. 1997, the contents and dynamics of different forms of phosphorus in two shrimp ponds and the inflow channel in Pantu cultivation area in Tong' an Bay, Xiamen were surveyed. The results showed that the content of particle phosphorus (PP) in shrimp ponds was significantly higher than that in the neighboring bay, while the content of dissolved organic phosphorus (DOP) in shrimp ponds was slightly higher, and the content of dissolved inorganic phosphorus (DIP) was evidently lower than that in the neighboring bay. PP was the main existing form of phosphorus in shrimp ponds (78 ..25 %), the contents of DOP and DIP were lower (14.82% and 6.93%, respectively), while in the neighboring bay phosphorus exists mostly in the forms of PP and DIP (44.49% and 46.39%, respectively), and DOP only constitutes 9.12%. The seasonal variations of the different forms of phosphorus in shrimp ponds are different from those in the neighboring bay.厦门市重大科技项目招标课题资助（1993－21－1－1

Settlement and metamorphosis of Styela canopus Savigny larvae in response to some neurotransmitters and thyroxin

【英文摘要】 The larvae of ascidian Styela canopus Savigny were treated with epinephrine, norepinephrine, L-DOPA, GABA and thyroxin to test the ability of these compounds to induce or inhibit larval settlement and metamorphosis. The results showed that epinephrine, norepinephrine and L-DOPA at the concentration of 1μmol/dm 3 induced larval settlement and metamorphosis in S. canopus, with short exposure (1 h) to 1 μmol/dm 3 of L-DOPA inducing rapid settlement. In contrast, GABA at the concentrations of 0.1 ～100.0 μmol/dm..

类泛素蛋白及其中文命名

泛素家族包括泛素及类泛素蛋白,约20种成员蛋白.近年来,泛素家族领域取得了迅猛发展,并已与生物学及医学研究的各个领域相互交叉.泛素家族介导的蛋白质降解和细胞自噬机制的发现分别于2004和2016年获得诺贝尔奖.但是,类泛素蛋白并没有统一规范的中文译名. 2018年4月9日在苏州召开的《泛素家族介导的蛋白质降解和细胞自噬》专著的编委会上,部分作者讨论了类泛素蛋白的中文命名问题,并在随后的\"泛素家族、自噬与疾病\"(Ubiquitinfamily,autophagy anddiseases)苏州会议上提出了类泛素蛋白中文翻译草案,此草案在参加该会议的国内学者及海外华人学者间取得了高度共识.冷泉港亚洲\"泛素家族、自噬与疾病\"苏州会议是由美国冷泉港实验室主办、两年一度、面向全球的英文会议.该会议在海内外华人学者中具有广泛影响,因此,参会华人学者的意见具有一定的代表性.本文介绍了10个类别的类泛素蛋白的中文命名,系统总结了它们的结构特点,并比较了参与各种类泛素化修饰的酶和它们的生物学功能.文章由45名从事该领域研究的专家合作撰写,其中包括中国工程院院士1名,相关学者4名,长江学者3名,国家杰出青年科学基金获得者18名和美国知名高校华人教授4名.他们绝大多数是参加编写即将由科学出版社出版的专著《泛素家族介导的蛋白质降解和细胞自噬》的专家
