Midwater trawl
There are two basic types of trawls used in Commonwealth fisheries: demersal trawls and midwater trawls. Midwater trawls fish in the water column and are used to catch a variety of pelagic fish species. Some fisheries may use paired trawls, where two boats pull one net. Midwater trawl nets may incorporate acoustic technology to tell the skipper the position of the net in the water column, the opening/spread of the net and the volume of fish entering the net. Additional instruments on the net can record the speed at which the net is traveling. Both demersal and midwater trawls use otterboards to keep the mouth of the net open.
