POD! Fish- DFG North Bay Aqueduct Larval/juvenile fish sampling March-July (1992-2004)

Name of study: North Bay Aqueduct Survey Program element: 096 Program manager: Kevin Fleming, [e-mail] Project Lead: Michael Dege, [e-mail] Agency: Department of Fish and Game, Bay Delta Division Address: 4001 North Wilson Way, Stockton, CA 95205 Phone: [phone], Fax: [phone] Purpose/Objective: This survey has two major foci: 1) Estimate and evaluate larval delta smelt loss at the State Water Project’s North Bay Aqueduct (NBA) due to entrainment and 2) Monitor abundance and distribution of larval delta smelt in the Cache Slough Complex and near Prospect Island. Prospect Island is a CALFED habitat restoration site and this sampling is used to evaluate whether delta smelt would use this site for spawning habitat. Future restoration of Prospect Island will warrant additional monitoring stations. The presence of delta smelt larvae in Barker Slough (Part of the Cache slough complex leading to the NBA) is a criterion for restrictions on NBA pumping. The 1995 Delta Smelt Biological Opinion mandates monitoring at the three Barker Slough stations in Barker Slough and the surrounding areas on a "recent-time" (within 72 hours) basis, posting delta smelt information on the world wide web so that interested parties may use this information for water management decisions. Data collected: Water temperature, surface electro-conductivity, water transparency, water volume sampled, tidal stage, sample time, tow depth, bottom depth, and fish catch. Geographic range of field work: Northern Sacramento-San Joaquin Delta. Number of sites: Eight stations. Period of record (start year): 1995. Size for complete data base for program element in KB (MB): 10+ megabytes. Number of individual files: One file or database contains all data.

研究目的/目标：本调查包含两大核心方向：1）估算并评估加州州水工程（State Water Project）北湾渡槽（North Bay Aqueduct, NBA）因夹带作用导致的幼体三角洲胡瓜鱼（delta smelt）损失情况；2）监测卡什泻湖综合体（Cache Slough Complex）及展望岛（Prospect Island）周边区域幼体三角洲胡瓜鱼的丰度与分布。展望岛为CALFED栖息地修复项目点，本次采样用于评估三角洲胡瓜鱼是否会将该区域作为产卵栖息地。未来对展望岛的修复工程将增设更多监测站点。巴克斯特泻湖（Barker Slough，为卡什泻湖综合体中通往北湾渡槽的河段）内幼体三角洲胡瓜鱼的存在情况，是限制北湾渡槽抽水作业的判定标准之一。1995年《三角洲胡瓜鱼生物意见书》要求以"近期时段（72小时内）"为频率，对巴克斯特泻湖内及周边的3个监测站点开展监测，并将三角洲胡瓜鱼相关信息发布至万维网（World Wide Web），以供相关方用于水资源管理决策。
采集数据：水温、表层电导率、水体透明度、采样水体体积、潮汐位相、采样时间、拖网深度、水底深度以及渔获数据。
野外作业地理范围：北萨克拉门托-圣华金三角洲（Northern Sacramento-San Joaquin Delta）。
监测站点数量：8个。
数据记录起始年份：1995年。
本项目单元完整数据库大小：10+兆字节（MB）。
单个文件或数据库即可包含全部采集数据。
