  abstract = {{O}ne challenge of acoustic observations of marine organisms is the identification of species, par-ticularly in shallow waters where high diversity occurs. {W}e deployed combining split-beam {EK}80 (70, 120 and 200 k{H}z) and {M}3 multibeam (500 k{H}z) echosounders to detect monospecific fish shoals in coastal shallow waters (5-60 m). {I}nnovative protocols for the specific allocation were tested, using (i) scuba divers census on fish shoals and (ii) towed scuba diver. {S}tereoscopic video system was also used to assess fish length and abundance and compare with the visual estimations of divers. {S}everal independent replicates of monospecific shoals from 5 fish species were obtained. {T}he combined used of the echosounders allows to have complementary morpho-logic, acoustic and spatial descriptors to correctly discriminate the shoals. {I}n addition, as the stereoscopic system has shown to provide precise measurements of individuals and could over-come the visual diver observations, our results suggest that a system equipped with cameras like a remotely controlled towed instrumentation platform could be used in a near future for ground trust in shallow and clear waters.},
