摘要：

The relationship between fish total length (TL) and mouth size in six species was investigated in light of the implications for the modelling of size selectivity of hooks. Significant non-linear relationships were found in three species, suggesting that optimal size at capture is not a linear function of hook size. These results strongly support the choices made in modelling skew-normal selectivity with optimal size at capture as a function of hook size.
