Differences in acoustic target strength pattern between fish with one- and two-chambered swimbladder during rotation in the horizontal plane

Original language description

Pattern of target strength (TS) during 360° rotation in the horizontal plane was studied for six common European fish species: brown trout (Salmo trutta), perch (Perca fluviatilis) bream (Abramis brama), roach (Rutilus rutilus), carp (Cyprinus carpio), and bleak (Alburnus alburnus). The TS distribution differed, between fish with one- and two-chambered swimbladders. For two-chambered fish, the TS transition between minima and maxima was linear, and the median of the TS value was similar to the mean. Forone-chambered fish TS distribution was skewed and median TS considerable smaller than the mean, The relationship between TS and fish aspect relative to the sonar beam, can be described by a linear model for fish with two-chambered swimbladders and by aquadratic model for fish with one-chambered swimbladders. This study provides new general equations for modeling the dependence of TS on any body aspect in the horizontal plane as well as equations for common European fish species.
