Harald Rosenthal (born 9 June 1937) is a German hydrobiologist [1] and fisheries scientist known for his work in fish farming, ecology, and international cooperation.
Rosenthal was born and raised in Berlin. From 1957 to 1962, he studied zoology, botany, chemistry, geography, and philosophy at the Freie Universität Berlin (Free University of Berlin). [1] From 1963 to 1968, he studied hydrobiology and fishery science in Hamburg. [1]
He wrote his doctoral thesis in 1969 on mass rearing of larval herring [1] and his habilitation thesis in 1981 on closed-circuit systems in fish farming and research. From 1989 to 2002, he was a professor at the Institut für Meereskunde (Institute for Marine Sciences) of Kiel University.
Rosenthal research focused on two areas:but
In addition to his own research, Rosenthal plays an important role in the international collaboration of hydrobiologists and aquaculturists, in particular between Canada and Germany as well as Israel and Germany.
Rosenthal is editor of the Journal of Applied Ichthyology and founder and president of the World Sturgeon Conservation Society (WSCS). [1] He holds honorary doctorates of the universities of Edinburgh (1985), Moncton (1996), and Szczecin (2003) and is a member of the Royal Swedish Academy of Sciences. [1]
Aquaculture, also known as aquafarming, is the controlled cultivation ("farming") of aquatic organisms such as fish, crustaceans, mollusks, algae and other organisms of value such as aquatic plants. Aquaculture involves cultivating freshwater and saltwater populations under controlled or semi-natural conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish. Mariculture, commonly known as marine farming, refers specifically to aquaculture practiced in seawater habitats, opposed to in freshwater aquaculture. Pisciculture is a type of aquaculture that consists of the culturing of fish to obtain fish and fish products as food.
Mariculture or marine farming is a specialized branch of aquaculture involving the cultivation of marine organisms for food and other animal products, in enclosed sections of the open ocean, fish farms built on littoral waters, or in artificial tanks, ponds or raceways which are filled with seawater. An example of the latter is the farming of marine fish, including finfish and shellfish like prawns, or oysters and seaweed in saltwater ponds. Non-food products produced by mariculture include: fish meal, nutrient agar, jewellery, and cosmetics.
Fish farming or pisciculture involves commercial breeding of fish, usually for food, in fish tanks or artificial enclosures such as fish ponds. It is a particular type of aquaculture, which is the controlled cultivation and harvesting of aquatic animals such as fish, crustaceans, molluscs and so on, in natural or pseudo-natural environment. A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery. Worldwide, the most important fish species produced in fish farming are carp, catfish, salmon and tilapia.
Fishery can mean either the enterprise of raising or harvesting fish and other aquatic life; or more commonly, the site where such enterprise takes place. Commercial fisheries include wild fisheries and fish farms, both in freshwater bodies and the oceans. About 500 million people worldwide are economically dependent on fisheries. 171 million tonnes of fish were produced in 2016, but overfishing is an increasing problem — causing declines in some populations.
A conventional idea of a sustainable fishery is that it is one that is harvested at a sustainable rate, where the fish population does not decline over time because of fishing practices. Sustainability in fisheries combines theoretical disciplines, such as the population dynamics of fisheries, with practical strategies, such as avoiding overfishing through techniques such as individual fishing quotas, curtailing destructive and illegal fishing practices by lobbying for appropriate law and policy, setting up protected areas, restoring collapsed fisheries, incorporating all externalities involved in harvesting marine ecosystems into fishery economics, educating stakeholders and the wider public, and developing independent certification programs.
The fishing industry includes any industry or activity concerned with taking, culturing, processing, preserving, storing, transporting, marketing or selling fish or fish products. It is defined by the Food and Agriculture Organization as including recreational, subsistence and commercial fishing, and the related harvesting, processing, and marketing sectors. The commercial activity is aimed at the delivery of fish and other seafood products for human consumption or as input factors in other industrial processes. Directly or indirectly, the livelihood of over 500 million people in developing countries depends on fisheries and aquaculture.
Daniel Pauly is a French-born marine biologist, well known for his work in studying human impacts on global fisheries and for being the most cited fisheries scientist in the world. He is a professor and the project leader of the Sea Around Us Project at the Institute for the Oceans and Fisheries at the University of British Columbia. He also served as Director of the UBC Fisheries Centre from November 2003 to October 2008.
Walter Bruch was a German electrical engineer and pioneer of German television. He was the inventor of Closed-circuit television. He invented the PAL colour television system at Telefunken in the early 1960s. In addition to his research activities Walter Bruch was an honorary lecturer at Hannover Technical University. He was awarded the Werner von Siemens Ring in 1975.
Bruno Hofer was a German fishery scientist, credited with being the founder of fish pathology.
Hydrobiology is the science of life and life processes in water. Much of modern hydrobiology can be viewed as a sub-discipline of ecology but the sphere of hydrobiology includes taxonomy, economic biology, industrial biology, morphology, physiology etc. The one distinguishing aspect is that all relate to aquatic organisms. Much work is closely related to limnology and can be divided into lotic system ecology and lentic system ecology.
The Centre for Environment, Fisheries and Aquaculture Science (Cefas) is an executive agency of the United Kingdom government Department for Environment, Food and Rural Affairs (Defra). It carries out a wide range of research, advisory, consultancy, monitoring and training activities for a large number of customers around the world.
Heinz Steinitz was a senior Israeli marine biologist and herpetologist, Professor and Chairman of the Department of zoology at the Hebrew University in Jerusalem. He laid the foundation for research and teaching in marine biology and oceanography in Israel. In 1968 he founded the Marine Biology Laboratory of the Hebrew University near Eilat, serving as its first director. He also served as a founding member of the Zoological Society of Israel and a co-founder of the Society for the Protection of Nature in Israel.
The following outline is provided as an overview of and topical guide to fisheries:
John Emil Halver was an American biochemist known for his research into the nutritional biochemistry, physiology, cellular biochemistry of fish. His work on the nutritional needs of fish led to modern methods of fish farming and fish feed production around the world. He held a position with the United States Fish and Wildlife Service as director of the Western Fish Nutrition Laboratory in Cook, Washington, where Halver and his staff carried out research on the nutrient requirements for Pacific salmon."
Günter Dietrich was a German oceanographer. He was the first to describe the Agulhas Current in detail, he provided essential contributions to the understanding of bottom water exchange in the North Atlantic and he shaped marine research in Germany after World War II.
Gordon Gunter was an American marine biologist and fisheries scientist. He is noted for his pioneering study of fisheries in the northern Gulf of Mexico, a topic to which he devoted his entire professional life over a career spanning 60 years. His own research, and that of the scientists under his direction, established an understanding of the ecology, comparative physiology of the plant and animal life, and commercial fisheries of the region, and he coined the phrase "fertile fisheries crescent" to refer to Mississippi Sound and adjacent waters along the United States Gulf Coast. He also pioneered the study of the comparative physiology of shellfish and fish.
Cecil von Bonde was a South African zoologist, fisheries scientist and oceanographer.
Andre Eric Punt is a South African fisheries scientist and mathematician, best known for his work on fisheries stock assessment. He received the K. Radway Allen Award in 1999 for his contributions to fisheries science.
Flower Ezekiel Msuya is a Tanzanian phycologist. She specialises in algaculture and integrated aquaculture.
