1. 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 ... (2005) method, and this suggests that the current method is adequate under circumstances of low evasion ... and when good knowledge exists that zero observations reflect zero illegal fishing. 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. One of the features ... ; • 50% coverage – this is the basic patrol schedule shown in Table 1. The illegal vessels arrived no ...
