Appendix 3 to Annex III Condition for fisheries with certain towed gears authorized in ICES Subareas III, IV, V, VI and VII and ICES divisions VIII a, b, d, eX1

Specifications of 100 mm, measured as inner opening, square mesh window in the rear tapered section of the trawl, Danish seine or similar gear with a mesh size equal to or larger than 70 mm and smaller than 100 mm.

The window shall be a rectangular section of netting. There shall be only one window. The window shall not be obstructed in any way by either internal or external attachments.

The window shall be inserted into the middle of the top panel of the rear tapered section of the trawl just in front of the untapered section constituted by the extension piece and the codend.

The window shall terminate not more than 12 meshes from the hand braided row of meshes between the extension piece and the rear tapered section of the trawl.

The length and the width of the window shall be at least 2 m and at least 1 m respectively.

The meshes shall have a minimum mesh opening of 100 mm. The meshes will be square meshes, i.e. all four sides of the window netting shall be cut all bars.

The netting shall be mounted such that the bars run parallel and perpendicular to the longitudinal axis of the codend.

The netting shall be single twine. The twine thickness shall be not more than 4 mm.

It shall be permitted to attach a selvedge on the four sides of the window. The diameter of this selvedge shall be no more than 12 mm.

The stretched length of the window shall be equal to the strength length of the diamond meshes attached to the longitudinal side of the window.

The number of diamond meshes of the top panel attached to the smallest side of the window (i.e. one metre long side which is perpendicular to the longitudinal axis of the codend) shall be at least the number of full diamond meshes attached to the longitudinal side of the window divided by 0,7.

The insertion of the window into the trawl is illustrated below.
