ANNEX V. Equipment and method

The equipment used and the methods followed were identical to those described in Annex I of the first part of this volume with two minor differences.

  1. The classification of echorecordings was made as follows:

    1. Recordings of true larger schools or dense layer mostly in upper water. These will most often derive from pelagic schooling fish usually of smaller size, e.g., clupeids, scads.

    2. All other fish recordings which especially comprised looser aggregations of smaller and larger fish near bottom. These are ascribed to demersal or semi-demersal fish such as grunts, seabreams, groupers, croakers, bigeyes, etc.

    3. Recordings of mesopelagic fish distributed in scattering layers.

  2. The integrator deflection was classified at two levels only: scattered (1–9 mm) and slightly gathered (10–20 mm).
