The Woods Hole Oceanographic

Institution announced the death July 9, 2006 of Scientist Emeritus John

H. Ryther of Hatchville at Falmouth

Hospital after a long illness. He was 83. Ryther was born July 17, 1922 in

Newton, Mass., and graduated from

Newton High School. He received his A.B. degree in 1947, M.A. degree in 1950 and Ph.D. degree in 1951 from Harvard University, where he was a student of George Clarke.

From 1942 to 1945 he served in the

U.S. Army air force as a pilot, flying 83 combat missions in Europe, and was discharged in 1945 with the rank of captain.

During the summer of 1950 Ryther spent the month of August at the

Institution working in George

Clarke's lab in Bigelow. Although his doctoral thesis was on plankton phys- iology, his interest and experience at that time were in fish ecology. In the winter of 1949-1950 he worked with

Jerry Collins stocking the Mashpee

River with hatchery raised trout to force the native trout out to sea. The following April he wrote to Alfred

Redfield to apply for a summer fel- lowship, which he was granted, and he began working with Dr. Belding although he also pursued studies of the physiology of unicellular algae isolated from Great South Bay and the effects of salinity on algal growth.

He joined the WHOI staff full time as a research associate in marine biol- ogy in October 1951, working with

Buck Ketchum and others. In 1956 he was appointed a marine biologist, and in 1961 he was asked to assume overall responsibility for planning the biological program of the

International Indian Ocean

Expedition. He and other members of the Biology Department and more than 150 scientists from the U.S. and abroad participated in this major international program, which utilized the converted presidential yacht

Williamsburg, recommissioned

Anton Brunn, to collect data on par- ticle and dissolved organic carbon in the Indian Ocean and Arabian Sea.

In 1963, Ryther was appointed a

Senior Scientist, and with the organi- zation of the Institution into scientif- ic departments he became the first chairman of the Biology Department, serving from 1963 until 1970.

Through his interest in aquaculture, he secured funds in 1972 to build the

Environmental Systems Laboratory (ESL) on the Quissett Campus. In the algae ponds and heated/chilled raceways he and ESL staff raised shellfish, fish and seaweed in a con- trolled environment. He was well known for his experiments incorpo- rating advanced human waste treat- ment to grow algae as a source of food for shellfish. He also conducted simi- lar experiments at the Harbor Branch

Oceanographic Institution in Ft.

Pierce, Fla. In 1980, Ryther was named director of the Coastal

Research Center. He left WHOI the following year to become a professor of forest resources and conservation at the University of Florida in

Gainesville, where he helped develop a marine resources program, and later moved to Harbor Branch

Oceanographic Institution. He returned to the Institution in 1987 and was named a scientist emeritus at

WHOI in 1988. He wrote one of his last publications for Trout Unlimited on anadromous trout in salt water, visiting trout streams from Long

Island to the Canadian Maritimes.

During his career he published more than 120 scientific publications, and co-authored one of the first compre- hensive books on shellfish aquacul- ture. Through the years Ryther served as a consultant to numerous government and state agencies, utility companies and state water projects, including the National Science

Foundation, National Institutes of

Health, Bureau of Sport Fisheries and

Wildlife, New York State

Department of Education, National

Council on Marine Resources and

Engineering Development in

Aquaculture, Boston Edison

Company, and Maine Yankee Atomic

Power Company. He was a member of the corporations for many years at the Marine Biological Laboratory and the Bermuda Biological Station. people & companies
