Toxicity data from shellfish, zooplankton, phytoplankton, forage fishes and predatory fishes collected from lower Cook Inlet, Prince William Sound and the Kodiak Archipelago, Alaska during 2015-2021

This resource is comprised of data collected and compiled for NPRB project 1801, including paralytic shellfish poisoning toxin levels occurring in samples of forage fishes, predatory fishes, phytoplankton, zooplankton and bivalve shellfishes collected at a variety of locations in lower Cook Inlet, Prince William Sound, and the Kodiak Archipelago during Aug 2015-Oct 2021. Phytoplankton samples for Alexandrium catenella abundance collected in conjunction with phytoplankton toxicity samples have also been included. Samples predating this project (before June 2018) were held frozen until they were able to be analyzed for toxin content during the course of this project. Most fish samples were largely collected opportunistically by project partners and collaborators, including sport fishers as well as commercial fishers and processors. Hence, many of the sampling locations were estimated from maps and word of mouth, or were denoted roughly to the closest body of water (e.g., Kachemak Bay). Samples of shellfish, zooplankton and phytoplankton (including Alexandrium abundance) samples were collected largely at sampling locations leveraged from parallel projects.

本数据集由为NPRB项目1801收集整理的各类数据构成，涵盖2015年8月至2021年10月期间，在库克湾下游、威廉王子湾及科迪亚克群岛多个采样点位采集的饵料鱼类、掠食性鱼类、浮游植物、浮游动物与双壳类贝类样本中的麻痹性贝类毒素（paralytic shellfish poisoning toxin）含量数据。此外还纳入了与浮游植物毒性样本同步采集的链状亚历山大藻（Alexandrium catenella）丰度相关浮游植物样本数据。本项目启动前（2018年6月之前）采集的样本均以冷冻方式保存，直至本项目实施期间才开展毒素含量检测分析。多数鱼类样本由项目合作方与协作单位（包括休闲垂钓者、商业渔民及水产加工商）以机会性采样方式完成采集，因此多数采样点位通过地图与口头访谈进行估算，或仅粗略标注至邻近水域（例如卡彻马克湾）。贝类、浮游动物及浮游植物（含链状亚历山大藻丰度）样本主要依托平行项目的采样点位完成采集。
