在1973年至1976年期间，在表面和深度大于2000米之间，以大约两个月的时间序列对罗卡尔海槽的磷虾动物群进行了采样。长度/频率直方图的模式是连贯的至少4至6个月的时间，表明人口正在采样。增长率被确定为六个物种。Epipelagic物种的冬季检查的增长速度，但这种检查是不存在的Thysanopoda acutifrons，Nematobranchion boopis和柱螯蟹最大的增长。年产量比例：生物量已确定，均在先前确定的上层和沿海种群的数值范围内。冬季对深海鱼种生长率的控制不足，使这些鱼种的总体生长率有可能与温带、海洋上层、大陆架和沿海鱼种的总体生长率相当。
The euphausiid fauna of the Rockall Trough has been sampled in time series at approximately two-monthly intervals between 1973 and 1976 between surface and depths greater than 2000 m. Length/frequency histograms have modes that are coherent for periods of at least 4 to 6 mo, indicating that populations are being sampled. Rates of growth were determined for six species. Epipelagic species have winter checks to the growth rates, but such checks are absent in the growth of Thysanopoda acutifrons, Nematobranchion boöpis and Stylocheiron maximum. Ratios of annual production: biomass were determined and are all within the previously determined range of values for epipelagic and coastal populations. Lack of a winter check to the growth rate in deep-living species enables these potentially to have overall rates of growth comparable to those of temperate, epipelagic, shelf and coastal species.
