If this is not done, there is a risk of both damage to the net and unintentional mortality in fish in the catch. The rollers on the triplex are therefore equipped with an upper part with a larger diameter, called a cone, to regulate how quickly the raft is taken in. One monitors how quickly the base and raft counts come in by observing marks on the raft and base counts for each log. Based on these observations, you regulate how fast you pull in the raft to keep the net as straight as possible. For large parts of the year, purse seine fishing is carried out in the dark. Then it is difficult for the operator of the triplex to observe the log marks, and one is partly dependent on using light, even if this means that more fish are stuck in the net line. Such fish can lead to damage to the net, loss of catch and reduced quality of catch in the next cast. There is great uncertainty about which technology should be chosen to mark and identify the blocks on the note. Passive RFID (radio frequency identification systems) is most relevant, but suppliers can not guarantee either the reading of marks when they are covered by grooves or the marks' robustness to pressure and impact. Other relevant brands can be magnets, steel tags, RuBee (small chips that communicate with receivers using magnetism) and active RFID (which uses radio signals).
To develop a system for electronic reading of log marks. To find the right sensor technology and demonstrate the concept. To develop a working prototype.
