• Resumen

  • We have studied the application of ultrasonic techniques in marine aquaculture: in particular,monitoring of present biomass in open sea farming cages. The final goals are school behaviour controland the estimation of number and growing rate of the fishes. In order to fulfil these objectives it isnecessary to measure the dorsal and ventral cross-section of the species of interest, in differentmonostatic and bistatic configurations, using low cost commercial transducers that could be placed inproduction conditions.
