Reducing catches of small fish with T90 mesh

Project Scope Project Scope

Innovative solutions have also been developed and implemented in fisheries targeting fish species. Rotating the angle of mesh in the codend by 45 degrees creates greater mesh openings through which fish can escape. Known as T90 mesh, testing of a range of different mesh sizes in this orientation demonstrated extremely positive results with substantially fewer undersize catches and improvements in fish quality for vessels targeting whiting and haddock. T90 has been implemented as a gear option in the Celtic Sea and is increasingly popular with Irish fishers.
