A marine fish was named after him in 2015 (Chelidoperca santosi), by two of the world's leading fish taxonomists, Jeffrey Williams and Kent Carpenter. In the same year, an Islet in Zamboanga City was named in his honor, "Mudjie Wise Key Islet," by the people of Barangay Dita, Zamboanga City. Later, he was officially recognized by the City of Zamboanga and by the Bureau of Fisheries and Aquatic Resources (BFAR) as one of the prime movers of the sardine fishing closure in the peninsula that not only benefitted the city but the entire country as well.
