Sidney J. Holt (28 February 1926 – 22 December 2019[1]) was a British biologist who was a founder of fisheries science.
He was best known for the book On the Dynamics of Exploited Fish Populations which he published with Ray Beverton in 1957.
[6] The legacy of the 1957 Beverton and Holt treatise is commemorated in the volume Advances in Fisheries Science.
Originally the model had a more specific usage; it was devised to describe the dependence of recruitment on spawning stock biomass.
The three scientists on the panel (Kenneth Radway Allen, Douglas G. Chapman and Holt) were selected because they specialized in fisheries research but were not officially connected with Norway, the Soviet Union, the Netherlands, Japan or Britain, the countries conducting the whaling they were to study.
