FORAGE FISH MONITORING IN THE SALISH SEA

Numerous beach surveys have occurred and continue to occur in the Salish Sea (WA and BC), with the goal of documenting directly-observed indication of presence of sand lance and surf smelt spawning on beaches, and documenting the respective habitat. The Washington State Department of Fish and Wildlife (WDFW) defines forage fish as generally planktivores, consuming copepods, mysids, and diverse larval forms of other organisms. Forage fish species spawn intertidally (surf smelt and sand lance), subtidally (herring and some sand lance) and pelagically (anchovy). Much of the data gathering is performed by trained volunteers both in British Columbia and in Washington State. In fact, most of the procedures and data templates originate from the well-established WDFW Marine Beach Spawning program (https://wdfw.wa.gov/fishing/management/marine-beach-spawning). A very large number of Citizen Scientist organiztions participate in the data sampling and analysis. A few of the larger organizations are linked below. Two types of beach surveys occur: those identifying beach sediment suitable for forage fish (Pacific sand lance and/or surf smelt) spawning, and surveys for observed spawning evidence in the sediments. Winter survey data is normally updated in May, and summer survey data updated in November.

萨利希海（Salish Sea，涵盖美国华盛顿州与加拿大不列颠哥伦比亚省海域）长期以来持续开展海滩调查工作，其核心目标是记录海滩上直接观测到的玉筋鱼（sand lance）与浪漂胡瓜鱼（surf smelt）产卵迹象，并记录二者对应的栖息生境。华盛顿州鱼类与野生动物局（Washington State Department of Fish and Wildlife, WDFW）将饵料鱼（forage fish）定义为以浮游动物为食的类群，它们主要摄食桡足类、糠虾以及多种其他生物的幼体。不同饵料鱼类的产卵区位存在差异：浪漂胡瓜鱼与玉筋鱼在潮间带产卵，鲱鱼与部分玉筋鱼在潮下带产卵，而鳀鱼则在远洋层产卵。不列颠哥伦比亚省与华盛顿州的大部分数据采集工作均由经过培训的志愿者完成。事实上，绝大多数调查流程与数据模板均源自成熟完善的WDFW海洋海滩产卵调查项目（WDFW Marine Beach Spawning program，https://wdfw.wa.gov/fishing/management/marine-beach-spawning）。大量公民科学组织参与了数据采样与分析工作，部分规模较大的相关机构链接附于下方。本次海滩调查包含两类：一类用于评估适配饵料鱼（太平洋玉筋鱼和/或浪漂胡瓜鱼）产卵的海滩沉积物，另一类则用于搜寻沉积物中已观测到的产卵痕迹。冬季调查数据通常于每年5月更新，夏季调查数据则于每年11月更新。

背景与挑战

背景概述

该数据集专注于监测Salish Sea地区的饵料鱼类（如太平洋鲱鱼、沙丁鱼等），这些鱼类是海洋食物网的关键环节，为大型捕食者提供食物。数据集通过跨组织合作（包括太平洋鲑鱼基金会和原住民等）收集数据，旨在填补数据空白以支持管理和监管决策，时间覆盖2000年至2025年，数据以XLSX格式提供。
