A study of trawl mesh selectivity for English sole and rock sole in Hecate Strait, August 1-5, 1980 / by R.D. Stanley and D. Davenport.: Fs97-4/1637E-PDF
"The selectivity of trawl mesh for English and rock sole was examined, using three different codend (108-, 133-, and 152-mm) and four different intermediate (108-, 111-, 130-, and 146-mm) mesh sizes, internal measure. The small number of tows and various sampling difficulties precluded quantifying the selectivity ogives, but the 152-mm (6-in) codend retained fewer undersized rock and English sole. A similar mesh size in the intermediate seemed to increase escapement of juvenile English sole although this effect was not observed for rock sole. Catch per tow was too variable and the sample size was too small to determine accurately how larger meshes would affect commercial catches"--Abstract, page iii.
