IMOS - Larval Fish Sub-Facility - Database of Marine Larval Fish Assemblages in Australian temperate and subtropical waters (1983 - ongoing)

Larval fishes are a useful metric of marine ecosystem state and change, as well as species-specific patterns in phenology. This information sheds light on larval distribution and spawning for fisheries management needs. This dataset includes larval fish abundances collected from 12 voyages around Australia since 1983, as well as more recent data from the Marine National Facility (MNF). The backbone of the dataset is from five Integrated Marine Observing Systems (IMOS) National Reference Stations (NRS) (North Stradbroke, Port Hacking, Maria Island, Kangaroo Island and Rottnest Island), between 2014 and 2021 as part of the IMOS Larval Fish Monitoring Sub-Facility of the National Mooring Network Facility (data currently available up to 2021). This adds information to the biological, ecological and oceanic measurements already sampled at these long-term monitoring sites. For information on using the data from the NRS stations and research voyages, please refer to Smith et al., 2018. It is advised that anyone using this data should read this methodology or contact the project contact person to understand the nuances of each sampling and analysis chain.The fish larvae product is available as raw count product, where fish larvae are classified to the lowest taxonomic level possible (with 228 taxonomic groups identified so far, at either the Family, Genus, or Species level). Associated metadata includes location, temperature, salinity, net type, and tow volume.There is a static snapshot of the database as at March 2018 (https://dx.doi.org/10.4225/69/5ab33c62f9c52), and this has been documented in a Scientific Data publication (Smith et al., 2018). This metadata record provides access to the dynamic (most recent) version of the database, which can serve as a data repository for survey of larval fish assemblages in the region.

鱼类幼体是表征海洋生态系统状态与动态变化，以及物候学中物种特异性模式的有效指标。此类信息可为渔业管理工作提供幼体分布与产卵活动的相关参考依据。本数据集包含1983年以来澳大利亚周边12次科考航次采集的鱼类幼体丰度数据，以及来自海洋国家设施（Marine National Facility, MNF）的近年数据。本数据集的核心数据源自2014至2021年间，依托国家锚泊网络设施下属的整合海洋观测系统（Integrated Marine Observing Systems, IMOS）鱼类幼体监测子设施，在5个国家参考站（National Reference Stations, NRS）——北斯特拉德布罗克岛、哈克宁港、玛丽亚岛、袋鼠岛以及罗特内斯特岛——采集的样本，当前数据更新至2021年。该数据集补充了这些长期监测站点已有的生物学、生态学与海洋学观测数据。如需了解如何使用国家参考站及科考航次采集的数据，请参考Smith等人2018年的研究成果。建议所有使用该数据的人员先研读该方法文档，或联系项目联系人，以充分理解各采样与分析流程的细微差异。本鱼类幼体数据集提供原始计数数据产品，其中鱼类幼体已被鉴定至尽可能低的分类学层级——截至目前已识别出228个分类单元，涵盖科、属或种三级。相关元数据包含采样位置、水温、盐度、网具类型以及拖网体积等信息。本数据库2018年3月的静态快照版本已存档（https://dx.doi.org/10.4225/69/5ab33c62f9c52），相关内容已发表于《科学数据（Scientific Data）》期刊（Smith等人2018年的研究）。本元数据记录可获取数据库的动态（最新）版本，该数据库可作为该区域鱼类幼体群落调查的专属数据存储库。
