Portions of a 1979 analysis dealing with optimum‐size considerations in the Tortugas, Florida, pink shrimp (Penaeus duorarum) fishery are updated. The 1979 management advice remains essentially the same. The current target minimum size of 103 mm total length theoretically should produce a 14‐20% gain, compared to unregulated conditions, in weight yields from shrimp recruiting through the closure area during the peak fishing season, Gains in dollar value (ex‐vessel gross revenue) due to closure would be from 45 to 64% during the peak season. However, because of the natural protection already provided by untrawlable bottoms in some areas where small shrimp are abundant, these percentage gains probably are overestimates.
