Abstract:
This study emphasizes on the characterization of echo-sounder backscatters for fisheries application at micro level by remote sensing techniques. A method for
acoustic-based fish stock size estimation by vertical echo-sounder of fish schooling
in the mid-water area of East Coast of Peninsular Malaysia (ECPM) was carried out. The specific objectives of this study are: (a) to estimate stock size of pelagic species
based on backscatters acquired by echo sounder imaging; (b) to map the density of three pelagic fish species, i.e. Round Scad, Torpedo Scad and Ox-eye Scad; and (c) to analyse the relationship of vertical distribution of multi-species pelagic fish with
surrounding biophysical parameters (dissolved oxygen, temperature and salinity).
