6.4.2.4. Schaefer and Fox model

Using Schaefer and Fox model, MSY could be estimated by following equation.

MSY = - 0.25  • a² / b. (Schaefer)

MSY = - (1/d)  • exp. (c-1) (Fox)

FMSY = - 0.5 • a / b (Schaefer)

FMSY = - (1/d) (Fox)

In Schaefer equation, ‘a’ is the intercept and ‘b’ is the slope and this is replaced by ‘c’ and ‘d’ in Fox model.
