Figure 1. Annual official (solid line) and total (dotted line) and total catch in the Cuban spiny lobster fishery.
The log-likelihood resulting from the fitting of the environmental models show a best fitting for the model with the total values for catch and effort (Table 2). Because it provided lower values for the components (mainly for catch at age) and for the total log-likelihood used as objective function.
Table 2. The log-likelihood components resulting from the fitting of the environmental model to official and total values for catch and effort in the Cuban spiny lobster fishery.
The recruitment and stock size estimated by the models showed very similar historical behavior (Figure 2). These reached maximum values in the 80s, with decreasing trend since then to 2011, showing a recovery in the last 5 years. These variables reflect the addition of more catch (illegal fishing) giving higher values in the population estimates.
