In situ target strength observations on haddock

Abstract

In situ target strength measurements of ideally resolved haddock have been made using the ES-400 split-beam echo sounder. The measurements are compared with the mean target strength obtained simultaneously by counting / integration. Within the estimated confidence limits of the observation volume in the counting method the two estimates of mean target strength agreed, both being about 4 dB above the currently applied mean target strength of gadoids.
