Preliminary study of the retention mechanism of planktonic copepods in the Jiulong Estuary in China   总被引：1，自引：0，他引：1

The horizontal and vertical distribution patterns of five planktonic copepods,Calanus sinicus, Acartia pacifica, Tortanus derjugini, Acartiella sinensis and Pseudodiaptomus poplesia, predominant in the Jiulong Estuary, were investigated from May 2003 to April 2004. The results showed that the distribution of these copepods was related to the tidal period but that each species had its own specific pattern. C. sinicus showed no tidal vertical migration behavior and was thought to be a non-resident species in this estuary. Among Acartia pacifica,T. derjugini,Acartiella sinensis, more individuals occurred in the surface than in the bottom waters during flood tide, and the pattern was reversed during ebb tide. The epibenthic copepod P. poplesia usually remained in the bottom waters in the upstream part of the estuary, but it displayed strong tidally-oriented vertical migration in the middle reaches of the estuary.Taking into account the hydrographic characteristics of the Jiulong Estuary,it was hypothesized that the planktonic copepods in this estuary had more or less adopted the mechanism of vertically migrating to the surface waters during flood tide in order to make use of the inflowing tide, and then sinking to the bottom during ebb tide to avoid being carried out of the estuary by net outflow.  相似文献   

黄海小拟哲水蚤(Paracalanus parvus)丰度的季节变化   总被引：1，自引：0，他引：1  

张芳  孙松  杨波  吉鹏 《海洋与湖沼》2006,37(4):322-329

根据2001年3、5、6、7、8、11月黄海6个航次的大容量采水器(59L)中浮游动物的样品资料,对小拟哲水蚤无节幼体及该种桡足幼体和成体丰度的时空分布格局进行了研究。结果表明,小拟哲水蚤桡足幼体和成体3月份在整个黄海测区内的丰度较低;5月份除山东半岛南岸三个高值站位,外海相对比近岸高;6、7月份的丰度水平最高,7月份航次中,丰度最高的站位可达10555ind/m3,整个测区内,海州湾内侧高于外侧;8月份,测区内的丰度分布相对均匀,丰度较低;11月份,测区小拟哲水蚤的分布相对也比较均匀。小拟哲水蚤无节幼体的丰度在黄海测区内的分布格局与该种桡足幼体及成体丰度的分布格局在3、5、6、7月份比较吻合,在8、11月份吻合程度较差。不同月份小拟哲水蚤的分布与温度、盐度、叶绿素a的关系不尽相同;其受温度的影响相对较大,受盐度、叶绿素a影响较小。  相似文献

Distribution and characterization of Chilean populations of the brine shrimp Artemia (Crustacea, Branchiopoda, Anostraca)     

Oscar Zuñiga  Rodolfo Wilson  Francisco Amat  Francisco Hontoria 《International Journal of Salt Lake Research》1999,8(1):23-40

Hypersaline habitats in Chile, from marine solar salt pans to saline lagoons and pools in Andean salars, were prospected in search of Artemia populations. These saline ecosystems were characterized through physico-chemical parameters and ionic composition of their brines. Biometrics of cysts and nauplii, as well as morphometrics by using multivariate discriminant analysis for adult specimens evidenced that the Chilean populations of brine shrimp belong to A. franciscana. Cross-breeding results supported the former hypothesis of conspecific Chilean populations, and their differences with A. persimilis, also endemic to the New World, but restricted to Argentinean sites.  相似文献   

乳铁蛋白对大黄鱼仔鱼生长、存活和抗应激能力影响的研究     

王秋荣  何峰  林利民  王志勇  刘贤德 《海洋科学》2010,34(6):66-70

用不同水平(分别为T1组:0 mg/L;T2组:50 mg/L;T3组:100 mg/L;T4组:150 mg/L)乳铁蛋白(lactoferrin,简称LF)强化的卤虫(Artemia franciscana)幼体投喂9~23日龄大黄鱼(Pseudosciaena crocea)仔鱼。结果表明,摄食LF强化卤虫幼体的大黄鱼仔鱼其生长无明显改善(P0.05),但大黄鱼仔鱼的成活率和抗应激能力显著提高,T3(60%)和T4(80%)组的成活率显著高于T1(40%)和T2(30%)组(P0.05)。T4组大黄鱼仔鱼的耐干露能力最强,T4组和T3组的抗高盐度(65)应激能力明显的强于T1和T2组(P0.05),T4组和T3组之间无明显的差异(P0.05)。经4 h高温(32°C)曝露后,T1和T2组的仔鱼全部死亡,T4组和T3组的成活率分别为30%和23.3%。即仔鱼的成活率和抗应激能力受卤虫强化LF水平的影响显著,LF强化的有效剂量为不低于100 mg/L强化水体。  相似文献   

火腿伪镖水蚤对抑食金球藻中国株的摄食行为及摄食后的表现     

何学佳  韩棣棣  韩留玉  吕颂辉 《海洋学报(英文版)》2018,37(4):69-76

全球河口海域屡屡爆发褐潮,但我们对致因种抑食金球藻和浮游桡足类之间的营养关系还不甚清楚。我们就浮游桡足类火腿伪镖水蚤摄食抑食金球藻中国株的单种或混合饵料时的摄食行为和生长、发育等表现进行了研究。研究发现：火腿伪镖水蚤的无节幼体、桡足幼体和成体摄食单种抑食金球藻饵料时,摄食率和食物浓度之间的关系符合米氏方程。较之桡足类幼体和成体,无节幼体摄食抑食金球藻时的I_max（最大摄食率）值最大,同时大于其摄食中肋骨条藻的I_max值。通常情况下,火腿伪镖水蚤在摄食抑食金球藻和中肋骨条藻的混合饵料时避食抑食金球藻,但于无节幼体,这种情况并不明显。无节幼体摄食单种抑食金球藻饵料在无节幼体期末期死亡,无法进入桡足类幼体期,与饥饿状态下的个体相似。但是,饵料中抑食金球藻的存在对桡足幼体的生长无明显效应,但却极大地减少了成体的生殖率。我们的研究表明火腿伪镖水蚤无节幼体,在褐潮的控制中有潜在作用,然而,这种潜在控制作用由于桡足类种群的衰落难以持续。  相似文献   

Dietary separation between co-occurring copepods in a food-limited tropical coral reef of the Sanya Bay     

胡思敏  李涛  刘胜  黄晖 《海洋学报(英文版)》2020,39(4):65-72

Food differentiation among coexistent species in the field is important strategy for copepods to acquire materials and maintain population stabilization.In situ diet analysis of co-occurring six copepod species in coral waters of the Sanya Bay was conducted using a PCR protocol based on 18 S ribosomal gene.Various prey organisms were uncovered,including dinoflagellate,diatom,green algae and plant,protozoa and metazoan.All these spatially coexisting six species showed different dietary diversity,with the food niche breadth(B)ranging from 1.00(Temora turbinate in morning)to 10.68(Calanopia elliptica in night).While food overlap between all these copepods were low,with the average value of the diet niche overlap index being approximately 0.09.Even temporally co-existing species sampled from the same time point fed on different groups of prey items with the food overlap index of 0.04 to 0.07 in midday and night but 0 in morning.As the most important dominant copepod in the Sanya Bay,Subeucalanus subcrassus seems to be capable to regulate its feeding,by exhibiting a rhythm of herbivorous feeding in midday and carnivorous feeding in morning and night,to better coordinate with other competitors for utilization of food resources.For most copepods,none of the prey items belonged to the dominant phytoplankton in the ambient water,indicating that copepod can better their survival by widening the choice of potential food resources in food limited environment.The dietary separation observed here might be important strategy for copepod to maintain population stabilization and thriving in the Sanya coastal waters.  相似文献
