The Occurrence of an Exotic Bisexual Artemia Species, Artemia franciscana, in Two Coastal Salterns of Shandong Province, China

The alien halophilous Artemia species, Artemia franciscana, was found in Chengkou Saltern and Yangkou Saltern of Shandong Province, P.R. China. Although the indigenous parthenogenetic Artemia is detectable, the exotic species is dominant in both salterns. The cross-breeding tests between the exotic A. franciscana and 5 bisexual Artemia species were conducted. The results of hybridization and morphological observations on the exotic A. franciscana are briefly presented in this short communication.     

辽西地区高蛋白玉米气候适宜性研究

2004年4～9月，凌源市气象和农技部门合作开展了针对高蛋白玉米品种的气象条件试验，通过设不同小区、多重复试验和平行观测，综合多项指标筛选出适合当地气候条件下的优质玉米品种，初步得出了这些品种的生长发育特征特性和生育期气象指标。     

耐盐水稻地方品种的主要性状分析

通过对湛江地区水稻品种的耐盐性、品质性状及主要农艺性状进行分析,结果表明,"咸水禾”品种具有一定的耐盐性,可用1/5海水灌溉,但其耐盐性不高;灌溉水含盐量的高低,对株高和穗粒结构影响较大;3个品种的出糙率均偏低,外观品质较差.并指出增强抗盐性、提高品质应是目前改良耐盐水稻地方品种的主攻方向.     

Morphological and molecular evidence supports the occurrence of a single species of Zebrias zebrinus along the coastal waters of China

The so-called zebra sole includes a group of small flatfishes characterized by transverse band pairs on the ocular side and distributed throughout shallow waters along the coast of the Indo-West Pacific Ocean. Sev-eral species of the zebra sole have been recorded from the coastal waters of China. Morphological analysis of 1 107 specimens of the zebra sole from 15 successive localities along the China’s coast demonstrated that no significant variations among these localities were found on the basis of meristic counts and morphometric characters. Phylogenetic analysis based onCOI gene sequences of 14 individuals and D-loop of 22 indi-viduals from eight localities showed that they were indistinguishable among these localities. Therefore, both morphological and molecular evidence supported the occurrence of a single species of the zebra sole along the China’s coast. The available name for this species isZebriaszebrinus （Temminck and Schlegel, 1846） in-stead ofZ.zebra （Bloch, 1787）.Zebrias fasciatus（Basilewsky, 1855） andSolea ommatura （Richardson, 1846） are considered here as two synonyms ofZ. zebrinus.     

小辣椒映红致富路

调整优化产业结构 增强养殖业发展后劲

抓好产业结构调整,是加快养殖业发展,提高效益,增强后劲的一项重要措施,也是发展生态型渔业,实施可持续发展战略的必由之路。长岛县是以渔业为主的海岛县,养殖业在渔业中占据很大比重。1997年,养殖业收入占全县渔业收入的7成以上。近年来,随着市场经济的发展和海洋生态环境的变化,原有单一的养殖品种和单一的养殖形式,以及粗放型的生产管理,已越来越跟不上当今养殖业发展要求,特别是去年鲍鱼、扇贝因发生病害大面积减产,使我们更加清醒地认识到加快结构调整的必要性,增     

青岛市崂山区海洋休闲渔业发展研究

崂山区内领海基线之内的海域面积3700km^2,可用于养殖的海域面积2万km^2,目前崂山区海水养殖面积2215hm^2,养殖品种主要是鲍鱼、海参、对虾、扇贝等,但根据青岛市政府的统一布局,为优化滨海景观,清理潮间带和近岸水域的养殖设施,并进行渔业生产结构调整,也就是说,崂山区近岸海域相当大的部分要让位于旅游,如何
