ACOUSTIC CLASSIFICATION OF FRESHWATER FISH SPECIES USING ARTIFICIAL NEURAL NETWORK: EVALUATION OF THE MODEL PERFORMANCE
Abstract: Hydroacoustic
techniques are a valuable tool for the stock assessments of many fish species.
Nonetheless, such techniques are limited by problems of species identification.
Several methods and techniques have been used in addressing the problem of
acoustic identification species and one of them is Artificial Neural Networks
(ANNs). In this paper, Back propagation (BP) and Multi Layer Perceptron (MLP)
of the Artificial Neural Network were used to classify carp (Cyprinus carpio),
tilapia (Oreochromis niloticus), and catfish (Pangasius hypothalmus).
Classification was done using a set of descriptors extracted from the acoustic
data records, i.e. Volume Back scattering (Sv), Target Strength (TS), Area Back
scattering Strength, Skewness, Kurtosis, Depth, Height and Relative altitude.
The results showed that the Multi Layer Perceptron approach performed better
than the Back propagation. The classification rates was 85.7% with the multi
layer perceptron (MLP) compared to 84.8% with back propagation (BP) ANN.
