     Assessing the taxonomy of fish is important in order to manage fish populations, regulate fisheries, and remove the exotic invasive species. Automating this process saves valuable resources of time, money, and manpower. Current methods for automatic fish monitoring rely on a human expert to design features necessary for classifying fish into a taxonomy. This work uses a method using Evolution-COnstructed (ECO) features to automatically find features that can be used to classify fish into a taxonomy. Rather than relying on human experts to build features sets to tune their parameters, our method uses simulated evolution to construct series of transforms that convert the input signal of raw pixels of fish images into high quality features. The effectiveness of ECO features is shown on a dataset of four fish species where using five-fold cross validation an average classification rate of 99.4% is achieved. Although we used four fish species to prove feasibility, this method can be easily adapted to new fauna and circumstances.
