An alternative method for estimating the level of illegal fishing using simulated scaling methods on detected effort
Abstract: A new method for estimating illegal fishing 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 performs better in the case of zero ...
