Abstract

In recent years, optical imaging has emerged as a promising tool for in situ observations of plankton. In this study, we aimed to compare the plankton community estimates obtained from a Video Plankton Recorder (VPR) imaging device with net-based approaches. By collecting VPR and net samples in clear waters with large-sized plankton and eutrophic waters with small-sized plankton, spatial and temporal patterns in plankton densities and community composition were compared. Furthermore, it allowed the evaluation of the performance of imaging methods under diverse hydrographic conditions. We observed pronounced spatial differences in density estimates. In the eutrophic site, the WP2 net densities consistently surpassed those from a VPR, while in the clear water site the observed densities of the VPR and a MultiNet were more similar. Variations in water column turbidity, plankton body size, plankton nets and their mesh size, and the total sampled water volume were found to likely play a role in the observed inconsistencies between the sampling sites. The results suggested that a VPR is particularly well-suited for use in clear waters inhabited by large-sized plankton. The VPR demonstrated potential in enhancing density estimates of fragile (Phaeocystis) and gelatinous taxa (Cnidaria and Ctenophora) in specific environments being non-invasive. Overall, the VPR and other optical imaging devices show valuable insights into zooplankton ecology and distribution, complementing density estimates of traditional net sampling methods, and enhancing our understanding of the role of zooplankton in marine ecosystems.

浮游生物成像:在不同的海洋环境中用光学成像补充基于网络的浮游生物群落评估
近年来,光学成像已成为浮游生物原位观测的一种有前途的工具。在这项研究中,我们的目的是比较浮游生物群落估计从视频浮游生物记录仪(VPR)成像设备和基于网络的方法。通过收集大型浮游生物的清澈水域和小型浮游生物的富营养化水域的VPR和净样,比较了浮游生物密度和群落组成的时空格局。此外,它允许在不同的水文条件下评估成像方法的性能。我们观察到密度估算的明显空间差异。富营养化样地WP2网密度始终高于VPR网密度,而清水样地VPR网密度与多网网密度较为相似。研究发现,水柱浊度、浮游生物体型、浮游生物网及其网孔大小以及总采样水量的变化可能在采样点之间观察到的不一致中发挥了作用。结果表明,VPR特别适合在大型浮游生物居住的清澈水域使用。VPR在特定的非侵入性环境中显示出增强脆弱(Phaeocystis)和胶状分类群(Cnidaria和Ctenophora)密度估计的潜力。总体而言,VPR和其他光学成像设备提供了对浮游动物生态和分布的有价值的见解,补充了传统净采样方法的密度估计,并增强了我们对浮游动物在海洋生态系统中的作用的理解。

期刊介绍: Limnology and Oceanography: Methods (ISSN 1541-5856) is a companion to ASLO''s top-rated journal Limnology and Oceanography, and articles are held to the same high standards. In order to provide the most rapid publication consistent with high standards, Limnology and Oceanography: Methods appears in electronic format only, and the entire submission and review system is online. Articles are posted as soon as they are accepted and formatted for publication. Limnology and Oceanography: Methods will consider manuscripts whose primary focus is methodological, and that deal with problems in the aquatic sciences. Manuscripts may present new measurement equipment, techniques for analyzing observations or samples, methods for understanding and interpreting information, analyses of metadata to examine the effectiveness of approaches, invited and contributed reviews and syntheses, and techniques for communicating and teaching in the aquatic sciences.
