Abstract

Hydroacoustic methods provide an important tool to detect and assess fishes and plankton. A variety of powerful acoustic devices are now in general use by fishermen, managers and scientists. Their success is based on several fundamental principles which make underwater remote sensing of biological parameters possible. A number of acoustic techniques, routinely used at the Pacific Biological Station in Nanaimo are briefly described. An echo integration survey of Pacific hake and an experiment that compares a visual and an acoustic count of salmon are used as illustrations
