We are going to conduct in river freshwater fish biomass study, would like
any suggestion and advise , in regards to instrument and technique that can
be used to collect data of fish size and biomass, in quatitative manner.

The river condition is about 3 meter deep, at 15 meters wide.

Is acoustic instrument useful in this condition ? 

Thanks
