USFWS Adult White Sturgeon Monitoring, San Joaquin River, 2012-2018

Overview The Central Valley Project Improvement Act (CVPIA) funds habitat improvement work and associated monitoring in the Central Valley of California to increase salmonid populations in furtherance of meeting CVPIA fish doubling goals. This data package contains three datasets for adult White Sturgeon (Acipenser transmontanus) monitoring in the San Joaquin River (SJR) conducted by the US Fish and Wildlife Service, Lodi Fish and Wildlife Office. The primary purpose for this sampling was to capture White Sturgeon and implant acoustic telemetry tags for a tracking project. Therefore, the data are useful for determining when and where White Sturgeon were captured, but they should not be used to determine actual distribution or abundance. SJR_Adult_WST_Set Data This dataset contains data from a sampling program using various methods to catch adult White Sturgeon in the San Joaquin River. Sets were made at targeted locations primarily from March-May in 2012-2018 (other dates were occasionally sampled). SJR_Adult_WST_Catch Data This dataset contains data for individual fish caught via gillnets, trammel nets, setlines, or angling in the San Joaquin River. Species and fork length were recorded for all fish. For White Sturgeon, girth, maturation, tag, and surgery information are provided. SJR_Fish_Taxonomy Data This dataset contains data for fish codes used in the Catch datafile. For each species that was captured, the Species codes are listed with the corresponding Interagency Ecological Program code, common name, taxonomy (Phylum, Class, Order, Family, Genus, and Species), and whether or not the species is native to the region.

《中央河谷项目改进法案》（Central Valley Project Improvement Act, CVPIA）为加利福尼亚州中央河谷的栖息地修复及配套监测工作提供资金支持，旨在提升鲑形目鱼类种群数量，以达成CVPIA设定的鱼类种群翻倍目标。本数据包包含美国鱼类及野生动物管理局洛迪鱼类与野生动物办公室开展的圣华金河（San Joaquin River, SJR）成年白鲟（Acipenser transmontanus）监测相关的三个数据集。本次采样的核心目的为捕获成年白鲟并植入声学遥测标签以用于追踪项目，因此本数据集仅可用于确定白鲟的捕获时间与地点，不得用于推断其实际分布或种群丰度。

圣华金河成年白鲟布设数据集（SJR_Adult_WST_Set Data）
该数据集涵盖圣华金河内采用多种捕获方法开展的成年白鲟采样项目数据。采样布设主要于2012-2018年的3-5月进行（偶有其他日期开展采样）。

圣华金河成年白鲟捕获数据集（SJR_Adult_WST_Catch Data）
该数据集包含通过刺网、三重刺网、定置延绳钓或垂钓方式在圣华金河捕获的单尾鱼类信息。所有捕获鱼类均记录了物种及叉长数据；针对白鲟，还额外提供了体围、成熟度、标签及手术相关信息。

圣华金河鱼类分类数据集（SJR_Fish_Taxonomy Data）
该数据集包含捕获数据文件中使用的鱼类编码相关信息。针对每一种捕获物种，均列出了物种代码、对应的跨部门生态项目（Interagency Ecological Program, IEP）代码、通用名称、分类学信息（门、纲、目、科、属、种），以及该物种是否为该区域本土物种。
