Historical Perspective
Chapter 1 (IFM)
Thought for today: "You cannot survive if you do not know the past." - Oriana Fallaci,
Italian journalist (1929-2006)

Objectives
Briefly outline major events important to
understanding the history of fisheries
management.
Compare and contrast the goals of
fisheries management in the past and the
present.

Fisheries Science and Management:
Historical Perspective
Thought for today: “Those who cannot remember the past are condemned to repeat
it.” – George Santayana, Spanish-American philosopher (1863-1952)

Rise of Ecosystem Management
–Biodiversity crisis
–Interconnectedness of ecosystems
–Human dimensions
–OSY
Based on Leopold’s “Land Ethic”
instead of the “Wise Use” ethic of
Pinchot

Late 1900’s and Early 2000’s
2 Principles of Leopold’s Ethic
1. Humanity is best served by preserving natural life support systems.
2. Indigenous ecological systems have intrinsic value that should be respected.

Late 1900’s and Early 2000’s
Modern Fisheries Management as Ecosystem Management
Olver et al. 1995
“The objective of modern fisheries management should be the protection, maintenance, and rehabilitation of native biota, their habitats, and life-support systems to ensure ecosystem sustainability.”
![Page 39: Fisheries Science and Management: Historical Perspectivejcsites.juniata.edu/faculty/merovich/ESS445_files/history_slides.pdf · Fisheries Science and Management: Historical Perspective](https://reader033.vdocuments.site/reader033/viewer/2022052023/6038b5fae2336b5b6517ae3a/html5/thumbnails/39.jpg)
Late 1900’s and Early 2000’s
Modern Fisheries Management as Ecosystem Management
(Olver et al. 1995)
Fundamental Principle
Aquatic ecosystems should be managed to ensure the long-term sustainability of native fish stocks
![Page 40: Fisheries Science and Management: Historical Perspectivejcsites.juniata.edu/faculty/merovich/ESS445_files/history_slides.pdf · Fisheries Science and Management: Historical Perspective](https://reader033.vdocuments.site/reader033/viewer/2022052023/6038b5fae2336b5b6517ae3a/html5/thumbnails/40.jpg)
Late 1900’s and Early 2000’s
Modern Fisheries Management as Ecosystem Management
(Olver et al. 1995)
Principles of Ecosystem Protection
1. The sustainability of fish stocks requires protection of the specific physical and chemical habitat utilized by members of that stock.
2. The sustainability of a fish stock requires the maintenance of its supporting native community.
