Identifier:nceas.902
Abstract:
Midwater trawl sampling September-December 1967-2006 Purpose of DFG's Fall Midwater Trawl survey is to evaluate potential water project effects on survival of young striped bass. The objective of the fall midwater trawl survey is to produce an index of monthly abundance of young striped bass. The sum of the monthly indices is compared to the summer townet abundance index to evaluate survival. Midwater Trawl Field Activities: From 1967 to 1978 the survey length was variable, sometimes starting in July or August, with September the usual starting month. The survey was never run beyond March. In 1980 the survey was shortened to cover the period of September to December due to variability in abundance indices associated with winter storm events. Midwater trawl Sampling stations cover a broad range of habitats.
