Hi Laura,

Considering as full maturity, when fish reaches 99%, the equation I've
derived is:

L99%=-1/b*(-4.59 -a)

For general purposes, you should consider

Ls=-1/b * (log((1-s)/s) - a)

were s is the maturity proportion

Cheers

Cristian

Hi all-

Was wondering if there was an equation to calculate length at 100%
maturity that uses the a and b parameters estimated from the logistic curve?

Cheers,

Laura
