 Midwater trawl |
In midwater trawling, a cone-shaped net can be towed behind a single boat and spread by trawl doors, or it can be towed behind two boats (pair trawling) which act as the spreading device. Midwater trawling catchespelagic fish such asanchovies,shrimp,tuna andmackerel, whereas bottom trawling targets both bottom living fish (groundfish) and semi-pelagic fish such as:cod,squid,halibut androckfish.
Whilst midwater trawling does not damage the seafloor (likebottom trawling), the method is not perfectly selective and results in relatively high levels ofdiscards of unwanted catches.[1]
