Stock and recruitment data for White Shrimp off the coast of Georgia (USA), 1979-2000.
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)
Stock-Recruit
Recruitment
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.
