Portable scientific system for lakes

For assessment of fish, plankton and macrophytes in lakes, mobile surveys from small boats are conducted with the acoustic beam pointing from the surface towards the bottom.

For assessment of fish close to the surface, the acoustic beam must be pointed horizontally.

Fish distribution examples:

EY60 Fresh water survey application

The most typical lake application is estimation of fish abundance. Often, surveys are run during the night since fish during the dark hours are distributed in the open water and are not hiding in daytime refugees.


The Sonar 4 PC application is specifically developed to do fish estimates in lakes.
