If the confidence limit curves had been included, I'd venture that Ricker wouldn't look so robust. A splatter gram without a "goodness of fit" description is deceitful statistics.

I see Carcassman captured above a key strength and weakness of Ricker style spawner - recruit relationships. When productivity is low, a population can be driven to near extirpation if that is the management objective. And managing for MSY invariably pushes population abundance downward. That's its track record.
