White Shrimp (Litopenaeus setiferus) stock and recruitment data from off the coast of Georgia (USA), 1979-2000.
A data frame with 22 observations on the following 3 variables:
Year of data
Spawning stock index – CPUE in June assessment surveys
Recuit index – commercial landings in pounds from Aug-Jan
A code of confidence for whether or not the stock value is known to come from the year shown (see the 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.
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.
