Harry Macdonald Kyle

Henry Macdonald Kyle (1872–1951) was a Scottish ichthyologist and fisheries scientist.

Kyle graduated from St Andrews University where he was a protégé of William Carmichael McIntosh. In 1903 he was appointed as Biological Secretary to the International Council for the Exploration of the Sea (ICES), based in Copenhagen. He was an expert on flatfish, especially plaice, and worked with Walter Garstang at Plymouth. Later he collaborated extensively with Ernst Ehrenbaum of the Museum of Natural History in Hamburg. He made important contributions to fisheries science and produced definitive works which were among the first scientific studies to address the issue of overfishing.

Kyle was one of the founders of the study of the bioeconomics of fishing and his argument that fish stocks were outside the scope of normal economics because economics are not subject to "natural law" was pioneering and remains generally accepted.
