本文报道了芬兰哲水蚤（Calanus finmarchicus）桡足幼体和成体的垂直分布和季节丰度。helgolandicus，C.本文描述了采自不列颠群岛西南部大陆架外大洋沃茨的Longhurst哈代浮游记录器系列中的细角哲水蚤、细新哲水蚤、小微哲水蚤和隆脊哲水蚤。选择取样区是因为东北大西洋主要哲水蚤桡足类的地理分布在该区域重叠。它标志着C分布的南部边界。finmarchicus，C. helgolandicus和C. tenuicornis、细角新单胞菌N. gracilis、N.米诺兰角脊状的这四个南部物种偶尔会在更北（60° N）的开阔海洋中渗透，但不会在这些北方纬度繁殖。在秋冬季节，C.芬马尔基库斯和C. helgolandicus主要以V期桡足类越冬，N. gracilis发生在上200米的水柱中的繁殖条件;所有桡足类阶段都存在。这桡足类在该地区全年繁殖，而C。细角羚主要在春季和夏季繁殖。研究了北大西洋哲水蚤科的地理分布和垂直分布与季节温度的关系，并比较了各种的繁殖策略。
The vertical distribution and seasonal abundance of the copepodite and adult stages ofCalanus finmarchicus, C. helgolandicus, C. tenuicornis, Neocalanus gracilis, Nannocalanus minorandCalanoides carinatusfrom a series of Longhurst Hardy Plankton Recorder hauls taken in the oceanic waters, off the continental shelf, to the south-west of the British Isles are described. The sampling area was selected because the geographical distributions of the major Calanidae copepods of the north-east Atlantic Ocean are shown to overlap in this region. It marks the southern boundary of the distribution ofC. finmarchicus, the central area ofC. helgolandicusand the approximate northern limit of distribution ofC. tenuicornis,N. gracilis, N. minorandC. carinatus. These four southern species occasionally penetrate further north (60° N) in the open ocean but do not breed at these northern latitudes. In autumn and winter, whenC. finmarchicusandC. helgolandicuswere overwintering below 400 m primarily as Stage V copepodites,N. gracilisoccurred in the upper 200 m of the water column in a breeding condition; all copepodite stages were present. This copepod reproduced throughout the year in this regions whileC. tenuicorniswas observed to breed primarily in spring and summer. The geographical and vertical distributions of the Calanidae are related to the observed seasonal temperatures of the North Atlantic and the breeding strategies of species arc compared.
