he enactment of the Magnuson Act in 1976:

focused more on sustainable yield approaches to U.S. fisheries.

opened up U.S. fisheries to foreign commercial interests.

allowed fishery managers to use economic and social factors to modify estimates of sustainable fish catches.

imposed restrictions on the amount of fish an individual could take.

I think it's focused more on sustainable yield so on. it does't really tell you in the textbook I am reading. it mentions open access

What part of this don't you understand?

"Purpose[edit]
The MSFCMA was enacted to promote the U.S. fishing industry's optimal exploitation of coastal fisheries by “consolidating control over territorial waters” and establishing eight regional councils to manage fish stocks.[5] The act has been amended several times in response to continued overfishing of major stocks. The most recent version, authorized in 2007, includes seven purposes:[6]

Acting to conserve fishery resources
Supporting enforcement of international fishing agreements
Promoting fishing in line with conservation principles
Providing for the implementation of fishery management plans (FMPs) which achieve optimal yield
Establishing Regional Fishery Management Councils to steward fishery resources through the preparation, monitoring, and revising of plans which (A) enable stake holders to participate in the administration of fisheries and (B) consider social and economic needs of states.
Developing underutilized fisheries
Protecting essential fish habitats"
