Target species: Blue Whiting and Mackerel fishery.

The effectiveness of this trawl is caused by its large net-part ability to direct the fish gathered in front of the trawl into the cod-end quickly and efficiently.

The part of the trawl where fish motorial reorientation takes place is considered the trawl’s «critical zone». It is possible to set back the critical zone, but the construction of our trawl focuses on the horizontal opening of the net (belly) part by using double cod-end, rather than the prolonging/elongating of the belly part. Our idea follows principles used by twin-trawls which are known to expand the overall path/area of the trawl.
