Marine Instruments is a Spanish company dedicated to the design and manufacture of electronic equipment, mainly for the fishing sector. They developed a Remote Electronic Monitoring System (REM) that uses automatic image capture for bycatch control on board fishing vessels.

For this REM, Marine Instruments has developed Beluga software, a program for the analysis and visualization of the images obtained by the observer. The program allows for a quick visualization of long hours of fishing, and allows for the review of fishing operations, checking for the amount of catch and bycatch.
