inserting a 50 mm square mesh panel (SMP)
to reduce capture of undersized fish in Mediterranean bottom trawls
Target species:
Atlantic horse mackerel, European hake, poor cod, broadtail shortfin squid, deep-water rose shrimp and all marketable species
Area, Vessel
8 hauls took place during 2012 on board the commercial trawler “Angela Madre” (206 kW, 22.7 m, 67 GT) in the Tyrrhenian Sea.

Gear type:
demersal trawl
Gear modification
A 50 mm square-mesh panel was inserted 8 m in front of a 50 mm diamond mesh codend in a Mediterranean bottom trawl. Small mesh covers were used to catch the fish escaping through the SMP and the codend.

Results:
The square mesh panel did not contribute much to the overall release efficiency. This may be due to the large distance it was from the codline (8 m).
