KRIS Gualala : Meta Information Page

This page contains detailed information about a data set in KRIS, including where the original data reside and how to contact the sources for the data. Data sets are linked to the appropriate page by means of the Meta Identifier. Many data sets can be linked to same page by sharing the same Meta Identifier.

Meta IdentifierCDFG_Creel_Data
Type of DataAdult coho salmon and steelhead catch data from 1950s and 1970s
OriginatorCalifornia Department of Fish and Game
DescriptionCreel census' were conducted in 1953-55 and again from 1972-1976 for adult coho salmon and steelhead catches in the Gualala River. Adult steelhead were seined and marked in conjunction with the 1974-75 and 1975-76 field data collection. This allowed a population estimate for adult steelhead in the Gualala using mark-recapture ratios.

PurposeTo document catch success rate for sport anglers for coho salmon and steelhead adults and to estimate adult steelhead populations in 1974-75 and 1975-76.
Data Quality InformationHigh, but sampling effort varied and there are no population estimates for the earlier period. Catch may also be substantially altered or depressed by high flows and turbidity, which decreases effectiveness of surveys.
Use ConstraintsAdult steelhead population estimates have wide confidence intervals because of the small sample of marked fish.
Supplemental InformationJuvenile electrofishing data (Jones and Harris,2000; Cox, 1995; NCWAP) and estuary seining data (Brown, 1986).

TitleAdult Coho and Steelhead Catch Data and Population Estimate
AbstractBoydstun (1974, 1976a, 1976b) documented CDFG surveys to gauge catch per unit effort of sportfishers for adult coho and steelhead from 1972-1976. Adult steelhead populations estimated for 1974-75 and 1975-76. Earlier survey memos were not available and are cited only secondarily.
