Size Selection of Antarctic Krill (Euphausia superba) in Trawls
Figure 5
Illustration of how the effective mesh openings in a trawl can vary depending of the attack angle of krill (5–90°) (A).
The light mesh is the real mesh in 90° view and the dark mesh is the effective mesh opening when projecting the mesh opening to a plan perpendicular to the towing direction. The lower mesh series (B) shows the potential effect of rotation of the cross section (CS1_CS2) in a 30° open mesh.
