More Ricker.................

The Ricker Curve is used to define MSY/H; the escapement that produces the maximum harvest. This is significantly different from the maximum (largest) population. According to Ricker Theory, increasing escapements do lead to larger returns, but smaller harvests as more of the fish go into escapement.

And, in management, the goal is first, foremost, and always maximizing dead fish.

Consider Fish Management as a business; "What is the minimum investment needed to maximize profit-to me".
