2.2.3 Smart weighing system at sea
Large fishing vessels currently use motion-compensated weighing system at sea in order to
directly measure and store raw weight of the catch. The boats’ movement at sea does not
allow determining the exact weight of the catch. Thus, the smart weighing system at sea
calculates the weight of catches while taking into account boats’ movement. Data is then
regularly sent to fish market and ports by satellite support to update landing forecast.
Some of these weighing systems integrate RFID

tags stuck on fish boxes in order to add
traceability features. New RFID tags allow reading and writing of information such as vessel
ID, voyage, specie, weight, size, date of capture and presentation. This technology makes it
possible to better respect quotas and control fishing bans for biological rest periods.
Correlations can be drawn between fish catches and landing, limiting the risk of fraud.
However, again, the question of the cost of such technology limits the use of the smart
weighing system, as it is 6 to 8 times more expensive than a weighing system on the ground.
In addition, the “non-legal” aspect of the dynamic-weight is still present for some
administrations, e.g. France, whereas Belgium, Norway or Denmark accept these
measurements.
