An alternative method for estimating the level of illegal fishing using simulated scaling methods on detected effort
Paper Title: An alternative method for estimating the level of illegal fishing using simulated ... effort is put forward. The results from this new method are similar to those of the Agnew and Kirkwood ...

The new method ... illegal fi shing in the area. If there has been no previous cruise, or if there has been no subsequent ... ille- gal fi sher has no knowledge of which area will be covered. Multiplying the above detection ... efforts (Dj), it will always produce a result of zero when there are no detections.
