Through Malacañang Proclamation No. 782 dated June 6, 2014, President Benigno S. Aquino conferred on Academician Angel C. Alcala the Rank and Title of National Scientist in recognition of his outstanding contributions to society, specifically his seminal and original research on the systematic, ecology, and diversity of Philippine amphibians and reptiles, and, marine biodiversity, reef fishes and conservation (marine-protected areas).
His studies on and advocacy of marine no-take zones led to a national policy  and program that established no-take marine protective areas which has resulted in more than a thousand of such marine no-take zones in the country and has become a model of coastal resource management and conservation adopted by many countries.  No-take marine reserves allows the build-up of marine biodiversity including fishery species as well as export of adult fish to areas (outside of MPAs) used as fishing areas, thereby enhancing fish yields of fishers.
He spent his professional life as an academic leader,an institution builder, and a public administrator.He was appointed as president of the Silliman University,here he helped institutionalize scientific research on marine biology and marine conservation.
