White Shrimp (Litopenaeus setiferus) stock and recruitment data from off the coast of Georgia (USA), 1979-2000.

## Format

A data frame with 22 observations on the following 3 variables:

year

Year of data

stock

Spawning stock index -- CPUE in June assessment surveys

recruits

Recuit index -- commercial landings in pounds from Aug-Jan

yrconf

A code of confidence for whether or not the stock value is known to come from the year shown (see the note)

## Source

From (approximately) Figures 2 and 3 of Belcher, C.N., and C.A. Jennings. 2004. Evaluation of stock-recruitment curves for white shrimp in Georgia. North American Journal of Fisheries Management 24:654-661. CSV file

## Note

No graph was shown for stock values vs. year so some stock values had to be haphazardly paired with recruit values -- especially for stock values between 2.5 and 3.0.

## Topic(s)

• Stock-Recruit

• Recruitment
