Date Time Who ---------- ----- -------- 03/29/2013 10:22 Bob_Magi Sampling in the Columbia River Estuary (approximately rkm 61-83) for PIT-tagged juvenile salmonids with a surface trawl was initiated on 25 March, 2013.Using the matrix PIT tag antenna developed in 2008 (8.5ft wide x 10ft tall fish passage tunnel) fixed to the cod end of the trawl enabling fish to pass through the system unhandled, we initiated sampling 3 days weekly.Sampling will increase to 5 days per week and finally to two daily sampling shifts 7 days per week as densities of PIT-tagged fish in the estuary increase and warrant the effort (typically in early May).This effort will remain consistent through the high fish density period of the juvenile outmigration season.As detection rates decrease (late June or early July) sampling will be reduced to 5 days weekly using one daily shift until sampling is halted. 01/02/2013 00:00 PTOC_Bot Annual log file initiation for TWX #### End of Event Log for TWX ###
