The bigger the holes in a fishing net, the more young fish will be able to escape, grow bigger and breed. So to protect young fish, managers set minimum mesh sizes for fishers’ nets.
Making sure that nets comply with government recommendations is the difficult job of fisheries inspectors. But it is not just fisheries inspectors who check mesh. Scientists also need to check the size of the mesh they use for surveys to make sure it is the standard size.
The Omega Mesh Gauge is the only instrument available that fully complies with the Commission Regulation (EC) No. 517/2008, published on 11 June 2008. This regulation describes the use of the instrument, the prescriptions and procedures, in order to achieve objective and legally tenable measurements.
