This thesis describes the computer modelling of an echo-sounder system used
in fish abundance measurement. Some years ago, Griffiths and Smith established
a computer model of a typical sonar system which was used to try to evaluate
the accuracy with which the number of targets could be estimated using the
integrated energy from the output of the system. However, the model was fairly
simple and did not take into account some important factors such as fish
behaviour which may have a significant effect on the estimates. This project has
taken these factors into account and has attempted to extend the earlier computer
model. [Continues.]
