  abstract = {{I}n order to convert acoustic abundance indexes into biomass is essential to establish the relationship between squid size dorsal mantle length ({DML}) and acoustic {T}arget {S}trength ({TS}). {W}e had carried out in situ measurement in 2012 off {B}aja {C}alifornia on {D}osidicus gigas. {F}or both frequencies, we found significant differences between modes of measured and predicted {TS} distributions, 6 and 11 d{B} for 120 and 38 k{H}z, respectively. {I}t is known that {TS} varies with several factors, including echosounder characteristics and transducer frequency and mainly the target orientation in the acoustic beam and many other biological variables. {I}n relation to squid behavior, during the capture operation small fish schools were observed in the area, which may suggest that squid were feeding. {F}urther observations and analysis are necessary in order to obtain reliable {TS} - {DML} relationship for jumbo squid before attempting acoustic biomass assessment methods to this important species.},
