Herring, Not Herring: Deep Learning Accelerates Detection and Classification of Underwater Species

Canadian machine learning researchers from the University of Victoria have teamed up with government marine biologists and private remote sensing specialists to develop a system for improved detection and classification of schools of herring. The world's oceans are home to some 200,000 species of sea animals, including over 18,000 species of fish, more than 1,800 sea stars, 816 squids, 93 whales and dolphins and 8,900 clams and other bivalves, according to a 2015 report from the World Register of Marine Species. Ocean fishes come in a variety of shapes, sizes, and colors and live in many different depth and temperature environments. This diverse marine world is however under threat. A 2016 United Nations Food and Agriculture Organization's World Fisheries and Aquaculture report reveals that 89.5 percent of the world's fish stocks are either fully fished (catches are close to the maximum sustainable yield) or overfished (catches are unsustainable).
