... This included the creation of eight Regional Fishery Management Councils (Councils) , which comprise representatives of commercial and recreational fishing, as well as the marine fisheries agencies of the coastal states.

... ACFCMA (Atlantic Coastal Fisheries Cooperative Management Act) : Federal law that established the authority of the Atlantic States Marine Fisheries Commission to develop enforceable conservation and management measures for Atlantic coastal fisheries (0–3 miles offshore)

... THE NATIONAL STANDARDS The cornerstone of the U.S. fisheries management process under the MSA is the 10 national standards,4 a set of statutory principles for conservation and management of the nation's fishery resources.
From page 22...
... The guidelines are meant to assist the Councils in the development of fishery management plans and implementing regulations by providing the secretary's interpretation of the national standards, against which plans will be reviewed. The guidelines provide detailed instructions for how the Councils may meet these statutory principles and factors they may need to consider in doing so.
From page 23...
... The secretary may approve, partially approve, or disapprove the FMP or amendment based on whether it meets the national standards and additional MSA requirements, as well as other applicable laws. Further opportunity for public input is provided during secretarial review of the amendment, as well as during the rulemaking process to implement proposed management measures.

... employs a slightly different approach for all of its FMPs, whereby the Council develops commercial management measures, while the states of California, Oregon, and Washington develop preferred recreational management measures that are adopted by the Council during the specifications process.25 Interstate Fisheries Commissions Prior to the adoption of the MSA in 1976, three Interstate Fisheries Commissions were formed by compacts of the coastal states: the Atlantic States Marine Fisheries Commission (ASMFC)

... and the Atlantic Coastal Cooperative Fisheries Management Act (ACFCMA; 1993) .27 Under the ACFCMA, the ASMFC is responsible for determining whether a state is in compliance with the required management measures and for forwarding any determination of noncompliance to the secretary of commerce for consideration and possible action.

... commercial and recreational fisheries management so as to ensure a healthy balance among sustainable fish stocks, ecosystem health, and productive coastal communities. In the United States, NOAA Fisheries conducts annual stock assessments to 31Pub.
From page 28...
... High-quality stock assessments, often depending on the quality and quantity of input data used in assessment modeling, provide scientific information with which to ensure continuity and consistency in developing fisheries management actions. DATA AND MODELS USED IN STOCK ASSESSMENTS Stock assessments usually require three primary categories of data: catch, stock abundance measures, and biological data.
From page 29...
... Time-series models used in stock assessments also have minimal or no assumptions on fish population dynamics. The minimum data requirement is catch or an abundance index time series (e.g., An Index Method [AIM]

... New England and Mid-Atlantic Management Regions The NOAA Fisheries Northeast Fisheries Science Center conducts stock assessments to support the New England and Mid-Atlantic Fishery Management Councils and the Atlantic States Marine Fisheries Commission. The Northeast Region Coordinating Council directs the stock assessment process, which includes two assessment tracks: management and research.

... , NOAA Fisheries Pacific Islands Fisheries Science Center, and Pacific Islands Regional Office designed to provide the best available scientific information for advising the Pacific Islands region fishery management. The WPSA includes two types of stock assessment: benchmark and update stock assessments.
From page 35...
... In general, data quality and quantity have been greatly improved for many stock assessments. The complexity of benchmark assessments has increased with more sophisticated and flexible modeling frameworks that can incorporate multiple sources of data, better quantify the dynamics of fish stocks and fishing fleets, and improve understanding of uncertainty.
From page 36...
... . CHALLENGES POSED BY RECREATIONAL FISHERIES DATA FOR STOCK ASSESSMENTS The most important piece of information for all of the stock assessment models is the amount of fish removed from a stock by commercial and recreational fishing activities.
From page 37...
... If the catch estimate is above the ACL, AMs may be in place that require overages to be paid back in the next fishing season. In any case, overages or underages will be accounted for in subsequent stock assessments, but such feedbacks are neither direct nor immediate.

From page 39...
... Conclusion: Stock assessments are the scientific backbone of the fisheries management process and vary greatly in complexity depending on the quality and quantity of available data. While stock assessment models and outputs are similar, each NOAA Fisheries Council region has developed a process for scheduling, conducting, and reviewing assessments that meets regional needs and ensures the quality of scientific information.
