Target strength and vertical distribution of smelt (Osmerus eperlanus) in the IJsselmeer based on stationary 200 kHz echosounder recordings

, 2013
Ventral target strength (TS) of smelt (Osmerus eperlanus) was measured using a bottom deployed Simrad EK60 200 kHz echosounder in the shallow lake Ijsselmeer (The Netherlands). Ventral TS values recorded (TS = 20 log10(L)–74.39) were lower but comparable
