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.
