Jaroslava Frouzová

Areas of expertise: The research interests include a development of hydroacoustical methodology like measurement of the acoustical size of European freshwater fish in different plane of observation and acoustical size of small underwater objects like fish fry, chaoborus larvae and gas bubbles. Further interest included fish ageing (mainly reading of the otoliths).
