Champ d’application

This standard applies to otter trawls (specifically those with a cod-end) used by motorized fishing vessels operating in the continental shelf fisheries outside the fishing restriction lines in the East China Sea and Yellow Sea. It is mandatory for all relevant fishing operations within these designated marine areas. It does not apply to fishing gears used in inland waters or other sea areas.

Exigences techniques

The standard strictly mandates the structural and dimensional requirements for trawl cod-ends to ensure sustainable fishing practices. The core requirement specifies that the minimum mesh size for the trawl cod-end must not be smaller than 54mm. This measurement specifically refers to the mesh size of a single-layer cod-end structure after water shrinkage. Furthermore, the standard explicitly prohibits the use of double-layer cod-end netting to prevent technical circumvention of the mesh size regulations. Compliance with these structural limits is mandatory for all manufacturers and operators.

Méthodes d’essai

Mesh size is expressed as the inner diameter of the mesh and must be measured according to the procedures defined in GB/T 6964. The pre-tension applied during these measurements must follow the specifications outlined in GB/T 6965. Basic terminology and definitions used for the fishing gear materials are referenced from SC/T 5001.
