Distribution of greenbone FL from Waihora, together with the distribution of the FL of fish captured with different mesh sized set nets. The red lines were calculated from the original catch data used by Dunn and Paul (2000), and were provided courtesy of Larry Paul (pers. comm. 2000). The blue lines were calculated from data in Hickford and Shiel (1997: 252: table 1). In three cases, very low values of N gave SD which are considered unreliable and were replaced with the mean of the four red curve SDs of 37.5 mm. The minimum legal size for greenbone is 350 mm, shown as the vertical dashed line. The minimum legal mesh size for greenbone set nets is 108 mm.
