A heatmap of where and how densely the seine fleet actually caught its fish.
The seine catch data layer shows a heatmap of the quantity of fish caught by the seine fleet.  


==MSP Challenge==
So far in the MSP Challenge we have two different seine fleets: purse seine and beach seine.
 
"A purse seine is a large net used to surround a shoal of pelagic fish. Once shot, the bottom of the net is drawn together by hauling in a long wire called the ‘purse line’ to form a huge cup shape of netting just below the surface of the water with the targeting fish inside. The net is gradually hauled onboard the vessel and the catch is taken onboard the vessel" (seafish, n.d.).
 
"A beach seine is a seine net operated from the shore. The gear is composed of a bunt (bag or lose netting) and long wings often lengthened with long ropes for towing the seine to the beach. The headrope with floats is on the surface, the footrope is in permanent contact with the bottom and the seine is therefore a barrier which prevent the fish from escaping from the area enclosed by the net. Two basic types of gear can be distinguished: seine nets without a bag (Fig. 1) and seine nets with a bag (Fig. 2). The first one do have, however, a central part with smaller meshes and more slack, which retains the fish caught. In the second one the fish are retained in the bag. It is not necessary for the bag to be exactly in the centre and in this case the wings are not of equal length." (FAO. 2024).


This puts no pressure on the ecosystem.

Description

The seine catch data layer shows a heatmap of the quantity of fish caught by the seine fleet.

So far in the MSP Challenge we have two different seine fleets: purse seine and beach seine.

"A purse seine is a large net used to surround a shoal of pelagic fish. Once shot, the bottom of the net is drawn together by hauling in a long wire called the ‘purse line’ to form a huge cup shape of netting just below the surface of the water with the targeting fish inside. The net is gradually hauled onboard the vessel and the catch is taken onboard the vessel" (seafish, n.d.).

"A beach seine is a seine net operated from the shore. The gear is composed of a bunt (bag or lose netting) and long wings often lengthened with long ropes for towing the seine to the beach. The headrope with floats is on the surface, the footrope is in permanent contact with the bottom and the seine is therefore a barrier which prevent the fish from escaping from the area enclosed by the net. Two basic types of gear can be distinguished: seine nets without a bag (Fig. 1) and seine nets with a bag (Fig. 2). The first one do have, however, a central part with smaller meshes and more slack, which retains the fish caught. In the second one the fish are retained in the bag. It is not necessary for the bag to be exactly in the centre and in this case the wings are not of equal length." (FAO. 2024).

MSP Challenge

Seine catch is a month-by-month, computer-generated data layer following this fleet's fishing catch calculated by the ecosystem simulation. This fleet doesn't fish in areas that are protected against seine fleets.

A plan can also include a change in the fishing efforts for this fleet per EEZ. Activate the Fishing controls by ticking the appropriate checkbox under section 2b in the Plan Wizard. Subsequently, change the Fishing effort sliders under the Fishing tab of the Plan Details (maximize the Plans Monitor and select your plan)
