The HADAS program creates echograms showing the reservoir's
bottom and the location of fish (Figure 3). The program measures
fish densities and relative fish sizes, with the ability to
provide detailed analysis by time and discrete depth strata.
Fish densities are reported as fish/hectare (fish/ha) or
fish/l,DDO m) of water surveyed. HADAS also provides information
and relative fish size based on the strength of target signals.
showing the reservoir's bottom, trees, and fish.
