Fish Stock Assessments: Prioritization and Funding

According to the National Oceanic and Atmospheric Administration (NOAA) in the Department
of Commerce, U.S. marine fisheries contribute over $100 billion annually to the American
economy and provide recreational fishing opportunities to millions of Americans.1 To continue
enjoying these benefits, NOAA manages marine fish stocks to ensure their sustainable use for
current and future generations.2 Specifically, NOAA's National Marine Fisheries Service (NMFS)
is responsible for fishery conservation and management. As part of its responsibility, NMFS
conducts fish stock assessments to estimate the size of the population of a fish stock. NMFS
also conducts fish stock assessments to examine whether a stock is overfished and provide
support for management measures, such as limits on how many fish can be caught annually,
among other things.

Eight regional fishery management councils are responsible for fisheries conservation and
management in specific geographic regions of the country. In addition, six NMFS regional
fisheries science centers are responsible for conducting fish stock assessments for certain fish
stocks in their geographic regions. The regional fishery management councils use NMFS' fish
stock assessments as a key tool for setting annual catch limits to help manage fish stocks.
According to NMFS, fish stock assessments can be expensive and time-consuming, and
therefore, NMFS cannot assess every stock each year. Consequently, setting priorities to
determine how often fish stocks should be assessed is important to ensure the efficient use of
resources.

There are two primary levels at which fish stock assessments can be conducted. The most
comprehensive level is known as a benchmark assessment, which may involve reviewing
multiple data sources and conducting new analyses and require many months to a year or more
to complete. A more streamlined, less time-consuming and costly level assessment is an update
assessment, which updates established benchmark assessment calculations using additional
data. The level of assessment needed for a particular fish stock is determined as part of
regional fish stock assessment priority setting processes involving NMFS' regional fisheries
science centers, NMFS' regional management offices, and the regional fishery management
councils, among others.

States, 2011, NOAA Technical Memorandum NMFS-F/SPO-128 (Silver Spring, MD: December 2012).
2A fish stock refers to either one species or a complex of comparable species managed as an entity in a geographic
area. Throughout this report, the term fish stock is used to mean one fish species or a fish stock complex.
