A renowned expert in fish ecology and aquaculture, known for developing innovative methods to improve fish farming and conservation practices.
Harald Rosenthal is renowned for his groundbreaking contributions to the fields of fish farming, ecology, and international cooperation, earning him a reputation as a leading authority in hydrobiology and fisheries science.
Born on June 9, 1937, in Berlin, Germany, Rosenthal pursued his passion for zoology, botany, chemistry, geography, and philosophy at the Freie Universität Berlin (Free University of Berlin) from 1957 to 1962.
He furthered his education in hydrobiology and fishery science at Hamburg, ultimately earning his doctoral thesis in 1969 on the mass rearing of larval herring and his habilitation thesis in 1981 on closed-circuit systems in fish farming and research.
Rosenthal's research focus was bifurcated, with one area of concentration on applied research, particularly on closed-circuit fish farms, and another on ecological aspects, specifically control and prevention of pollution, and sustainability, especially in developing countries.
From 1989 to 2002, he held the position of professor at the Institut für Meereskunde (Institute for Marine Sciences) of Kiel University, where he continued to advance his research and academic pursuits.
Rosenthal was one of the pioneering researchers to recognize the danger posed to ecosystems by the transport of marine life across vast distances in the ballast water of ships.
He actively lobbied for regulations and measures to combat this ecological threat, underscoring the significance of responsible and sustainable practices in the shipping industry.
Rosenthal has played a vital role in fostering international cooperation among hydrobiologists and aquaculturists, particularly between Canada and Germany, as well as Israel and Germany.
He serves as editor of the Journal of Applied Ichthyology and is the founder and president of the World Sturgeon Conservation Society (WSCS).
In recognition of his outstanding contributions, Rosenthal holds honorary doctorates from the Universities of Edinburgh (1985), Moncton (1996), and Szczecin (2003), and is a distinguished member of the Royal Swedish Academy of Sciences.
Harald Rosenthal's tireless efforts have not only advanced the understanding of hydrobiology and fisheries science but have also led to significant improvements in sustainability and environmental stewardship.
His work continues to inspire new generations of researchers and scientists, leaving an indelible mark on the fields of aquaculture and ecology.

Developed the system of binomial nomenclature, which is still used today to classify and name living organisms. This system has had a profound impact on the fields of biology, ecology, and conservation.
Born in 1769
A pioneering geographer and explorer who mapped much of South America and discovered the Caspian Sea's connection to the Black Sea, greatly advancing our understanding of the natural world.
Born in 1809
Developed the theory of evolution through natural selection, revolutionizing our understanding of life on Earth. This groundbreaking idea transformed the fields of biology, ecology, and beyond.
Born in 1822
