Details

This data is simulated from values reported in a paper by Porch, Wilson and Nieland titled "A new growth model for red drum (Sciaenops ocellaus) that accommodates seasonal and ontogenic changes in growth rates" which appeard in Fishery Bulletin 100(1) (was at http://fishbull.noaa.gov/1001/por.pdf, now off-line). They attribute the data to Beckman et. al and say it comes from measurements in the Northern Gulf of Mexico, between September 1985 and October 1998.
