    Abstract

    Many fisheries research and development projects include the evaluation of size and potential yield of the fish resources as an essential part of their objectives. While exploratory surveys depending on fishing trials alone are very time-consuming and expensive, and at best can only provide information about the distribution and abundance of the fish which are vulnerable to the type of fishing gear and method of fishing applied, the modern calibrated, highly sensitive acoustic instruments provide the under-water vision required to enumerate correctly and even to size the fish present in practically the entire water column.
