trials with square and diamond mesh codends
to increase escapees and reduce discards in the Mediterranean bottom trawl fishery
Target species:
Hake (Merluccius merluccius)
Area, Vessel
To compare the overall selectivity (gear and fisher) on the total hake (Merluccius merluccius) population entering the bottom trawl codend. The trial took place in the Southern Aegean Sea (Eastern Mediterranean) on board Takis-Mimis NX 411 (29m, 357 KW) NX 411 (29m, 357kW) during 2015.

Gear type:
demersal
Gear modification
A comparison was made of the catching performance of trawl codends made of (i) 40 mm diamond mesh (40D) (ii) 40 mm square mesh(40S) and (iii) 50 mm diamond mesh (50D)

Results:
40S square mesh showed a larger amount of escapees and a lower amount of discards compared to the diamond 40D & 50D. Similar selection behaviour by the fisher was defined for landings
