USFWS Larval White Sturgeon Monitoring, San Joaquin River, 2013-2017

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 larval White Sturgeon (Acipenser transmontanus) monitoring in the San Joaquin River (SJR) conducted by the US Fish and Wildlife Service, Lodi Fish and Wildlife Office. SJR_Larval_WST_Set Data This dataset contains data on an experimental sampling program using boat-mounted drift nets (D-frame nets), a large drift net attached to a stationary pontoon (pontoon net), and otter trawls to catch larval White Sturgeon in the San Joaquin River. Sets were made at targeted locations from March-July in 2013, 2015, 2016, and 2017. A total of ten White Sturgeon were captured in 2016 and 11 in 2017, all with D-frame driftnets. SJR_Larval_WST_Catch Data This dataset contains data for individual fish caught in the San Joaquin River. Species and fork length were recorded for most individuals. 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.概述 《中央谷项目改进法案（Central Valley Project Improvement Act, CVPIA）》为加利福尼亚州中央谷地区的栖息地改善工作及配套监测提供资金支持，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。本数据包包含由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）内白鲟（Acipenser transmontanus）幼体监测相关的三类数据集。 SJR_Larval_WST_Set 数据集 本数据集收录了圣华金河内用于捕获白鲟幼体的实验采样方案数据，采样方式涵盖船载漂流网（D形架网）、固定于固定式浮筒的大型漂流网（浮筒网）以及底拖网。采样作业于2013、2015、2016及2017年的3月至7月间在预设点位开展。2016年共捕获10尾白鲟，2017年捕获11尾，所有捕获个体均由D形架漂流网获取。 SJR_Larval_WST_渔获数据集 本数据集收录了圣华金河捕获的单尾鱼类相关数据，多数个体记录了物种信息与叉长数据。 SJR_Fish_Taxonomy_鱼类分类数据集 本数据集收录了渔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，均列出了其物种编码、对应跨部门生态项目（Interagency Ecological Program）编码、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。
