The high morphological similarity among billfish species (such as swordfish or blue marlin) makes accurate identification difficult, creating challenges for fisheries management. Misclassification can lead to quota non-compliance, overexploitation of protected species and economic penalties. As a result, innovative methods are needed to differentiate these species efficiently, combining scientific accuracy with industrial applicability to ensure sustainable fisheries and regulatory compliance.
AZTI has carried out the preliminary calibration of a non-destructive sensor based on NIR spectroscopy, capable of distinguishing blue marlin from other billfish species. This fast technology, which requires no invasive sampling, lays the groundwork for an identification system that can be applied in fish markets, on board vessels and in processing plants.
Initial validation of an innovative sensing method with strong potential for reliable, operational species identification.
A first step towards tools that facilitate quota compliance, improve traceability and reduce the risk of catching protected species.
A significant advance towards more accurate and sustainable fisheries management through non-destructive technologies.
