Cornerstones of Innovation
Developed and patented by the Marexi marine technology company and the Calvo Group, this system was devised to detect tuna species. It features a series of artificial vision elements and complex algorithmic analyses that help to facilitate onboard identification of different tune species (yellowfin, bigeye and striped), determine exact number and estimate their weight.
This system will provide rigorous real-time intelligence on the captures made by a vessel, enabling the information to be reported to authorities. This information is also extremely important from a scientific standpoint because it helps to minimise errors when estimating sizes and species (even making it easier to differentiate between young yellowfin and bigeye species, which are very difficult to distinguish at a glance), in addition to providing capture-related spatial and temporal data in real time.
The system will also enable shipowners to ascertain the exact value of the load they are carrying on board, and can potentially facilitate tuna classification into various holds, thereby saving time during unloading operations.
As a product of Calvo’s concern for the sustainability of marine ecosystems, the company developed the Calvoshark project. This involves a patented device designed between the Marexi marine technology company and the Calvo Group with the aim of attracting the attention of sharks and luring them away from the fishing grounds to thereby avoid accidentally capturing them.
Stimuli that attract sharks in their natural environment are used to do this and include electromagnetic pulses and acoustic generators; optical generators: concentrated compounds that stimulate taste and smell in sharks; and generators employing low-frequency vibrations, which simulate the movements of wounded fish.
