model of fish over exploitation
...oitation of
fish in the bay of biscay (france). I know only the level of catch and
the fishing effort (see data below) by year.
My model is composed by the following equations:
* the growth function
Gt(St) = r*St*(1-St/sbar)
with Gt the growth of each period t
r intrinsec growth of the stock
sbar carriyng capacity of the stock
St the fish stock of each period t
* the production function
Ht(St, Xt) = alpha*St*Xt
Ht the catch for each period t
Xt fishing effort for each period t
alpha parameter of boat productivity
* the dynamic of the fish stock
S(t+1) = S(t) + Gt - Ht
I would like to modelise th...
