Our understanding of the distribution and abundance of gelatinous mesozooplankton (0.2–20 mm) has been largely determined from the deployment of net sampling devices. Although zooplankton nets have been shown to underrepresent the abundance of certain gelatinous taxa in comparison to data from optical systems, nets still provide relative abundances for gelatinous zooplankton. A potential source of standardized, long‐term, and broad‐scale data for the relative abundance and distribution of gelatinous mesozooplankton is from fisheries monitoring programs which use zooplankton samplers such as the high‐speed Gulf VII sampler to capture fish eggs and larvae in shelf and offshore waters. To evaluate the use of the Gulf VII sampler as a source of gelatinous mesozooplankton data, this study collected zooplankton samples using both a Gulf VII sampler and a vertical ring net at 15 stations off the northwest Irish and Scottish coasts in July 2017. The difference in the estimates of gelatinous mesozooplankton abundance and taxon richness of the Gulf VII and the ring net samples were not significant (mean abundance: Gulf VII = 135.7 ± 79.7 ind. m⁻³, ring net = 149.7 ± 66.5 ind. m⁻³; taxon richness: Gulf VII = 15.2 ± 2.4, ring net = 15.4 ± 2.5), although the Gulf VII underestimated the abundance of the appendicularian Oikopleura sp. by a factor of 9.7 when compared to the ring net. Our findings describe how added value can be provided to already existing zooplankton monitoring programs while enhancing the temporal and spatial coverage of data available for gelatinous mesozooplankton.

一种监测胶质中层浮游生物的新型平台：高速海湾七号采样器可量化类似于环网的胶质中层浮游生物

我们对凝胶状中层浮游生物（0.2–20毫米）的分布和丰度的了解很大程度上取决于净采样装置的部署。尽管已显示浮游动物网与光学系统数据相比不足以表示某些凝胶状类群的丰度，但该网仍可为凝胶状浮游动物提供相对丰度。胶质中游浮游动物相对丰度和分布的标准化，长期和大规模数据的潜在来源来自渔业监测计划，该计划使用浮游动物采样器，例如高速海湾七号采样器来捕获架子上的鱼卵和幼体和近海。为了评估使用海湾七号采样器作为中型浮游动物胶状数据的来源，⁻³，环网= 149.7±66.5 ind。m ^-3；分类单元丰富度：海湾VII = 15.2±2.4，环网= 15.4±2.5），尽管海湾VII低估了附生动物Oikopleura sp。的丰度。与环网相比，系数是9.7倍。我们的发现描述了如何为现有的浮游动物监测程序提供增值，同时增强对中型浮游动物胶凝体可用数据的时空覆盖。
