| Big Creek Pit Tags |
| The BCPITTAGS database is used to store data from an Oncorhynchus mykiss (steelhead/rainbow
trout) population dynamics study in Big Creek, a coastal stream along the Big Sur
coast in Monterey County, California. The Landscape Ecology team at the Fisheries
Ecology Division in Santa Cruz, CA is investigating the life history of this relatively
small O. mykiss population to determine its significance in the persistence of the
larger South-Central California Coast Steelhead Distinct Population Segment (DPS),
which includes anadromous O. mykiss populations from the Pajaro River up to (but not
including) the Santa Maria River, to see how these small coastal streams with little
human-related impacts may contribute to DPS viability and resiliency. The database
stores data from mark-recapture surveys, fish movement data collected via instream
PIT tag readers, and stream environmental data. The data will be assimilated into
a stage-structured population model, where stages include life history stage and location.
Movement and survival rates will be determined and analyzed using data from the stationary
PIT tag readers and mobile tracking devices. |
