To do fish farming, you need to know the types of fish to be cultivated. This is because the type of fish will affect how it is
handled and managed. So, this study aims to develop an image processing system for classifying fish species, especially fish
that are cultivated, with a combination of the K-Nearest Neighbor (K-NN) algorithm and Principal Component Analysis (PCA).
The feature extraction used is feature extraction based on its color and shape. The K-NN algorithm can group certain objects
by considering the shortest distance from the object. According to the best criteria, the PCA method is employed in the
meanwhile to decrease and keep the majority of the relevant data from the original characteristics. Based on the test results,
the accuracy value obtained is 85%. The use of a combination of the K-NN and PCA algorithms in the image classification of
fish species in the research that has been done has been shown to be able to increase accuracy by 7.5% compared to only using the K-NN algorithm
