Abstract:
Hilsa is the national fish of Bangladesh. Bangladesh is earning a lot of foreign currency by
exporting this fish. Unfortunately, in recent days some unscrupulous businessmen are
selling fake Hilsa fishes to gain profit. The Sardines and Sardinella are the most sold in the
market as Hilsa. The government agency of Bangladesh, namely the Bangladesh Food
Safety Authority said that these fake Hilsa fish contain high levels of cadmium and lead
which are detrimental for humans. In this research, We have proposed a method that can
readily identify original Hilsa fish and fake Hilsa fish. Based on the research available on
online literature, we are the first to do research on identifying original Hilsa fish. We have
collected more than 16,000 images of original and counterfeit Hilsa fish. To classify these
images, we have used several deep learning based models. Then the performance has been
compared between them. Among those models, DenseNet201 achieved the highest
accuracy of 97.02%.
