Abstract
A system and method for sorting fish where the system comprises;—a trawl (2) consisting of at least one trawl bag (3, 3′, 3″), and where the at least one trawl bag (3, 3′, 3″) has an opening which covers a part of an inflow area in the trawl (2),—at least one monitoring device (6) arranged in connection with the inflow area and where signals can be transmitted to a processing unit from the at least one monitoring device (6), and—where a device, based on data from the processing unit, can move the opening in the at least one trawl bag (3, 3′, 3″) to a position where fish flow through the inflow area but on the outside of the at least one trawl bag (3, 3′, 3″).
Claims7
A system for sorting fish where the system comprises;
- a trawl (2) consisting of at least one trawl bag (3, 3′, 3″), and where the at least one trawl bag (3, 3′, 3″) has an opening which covers a part of an inflow area in the trawl (2),
- at least one monitoring device (6) arranged in connection with the inflow area and where signals can be transmitted to a processing unit from the at least one monitoring device (6), and
- where a device, based on data from the processing unit, can move the opening in the at least one trawl bag (3, 3′, 3″) to a position where fish flow through the inflow area but on the outside of the at least one trawl bag (3, 3′, 3″).
A method for sorting fish when using a trawl (2) where the method comprises the steps;
- monitoring an inflow area in the trawl (2) by employing at least one monitoring device (6),
- transmitting the signals from the monitoring device (6) to a processing unit, and
- based on data from the processing unit, employing a device in order to move an opening in the at least one trawl bag (3, 3′, 3″) to a position where fish flow through the inflow area but on the outside of the at least one trawl bag (3, 3′, 3″).
