Dear SS experts,
I am working with
a sex-specific length-based model for hake and have a question
about growth.
More
specifically, the question is about the parameters that control
the linear growth period.
In the control
file, I set "_Age(post-settlement)_for_L1 (Amin)" to
0.5 and then let L1 be estimated. The model estimates L1 to be
20.21. However, when we look at the plot (attached), the growth
is linear up to an age beyond 0.5, and the associated length is
not the value of 20.21 that was estimated for L1.
I've read that
Amin should be based on real age and not calendar age, but I
believe it should be correct as it is, since in our case the
spawning month is 1, and we have two settlements in months 1 and
7. I understand that Amin should be set relative to the first,
right? Then I understand that Amin at 0.5 means that the fish
will have length L1 in July and the growth will be linear until then.
Many thanks in advance,
Marta Cousido Rocha
