Magnuson‐Stevens Act

• Originally Passed in 1976– 200 mile Exclusive Economic Zone– Regional Council system to manage the resources– Capitalization to take advantage of resources in the EEZ

• 1992 Reauthorization “Sustainable Fisheries Act” (SFA)– 16 years later and concerns are more about overfishing than increasing capacity

– MSY, precautionary principle, 10 year rebuilding– Biological References (MFMT, MSST, OY)

Magnuson‐Stevens Act

• 2006 “Magnuson‐Stevens Fishery Conservation and Management Reauthorization Act”  (MSRA)– Existing law not enough to end overfishing– Address scientific and management uncertainty– End overfishing “immediately”– Cannot exceed SSC “Fishing Level Recommendations”– Led to Accountability Measures (AMs), Annual Catch Targets (ACT), Annual Catch Limits (ACL), Overfishing Level (OFL), Allowable Biological Catch (ABC)

• What’s Next?– Flexibility

What is the SSC ?

• Scientific and Statistical Committee• Provide Peer Review

– anything coming before the Council• Make Recommendations

– some are binding, like OFL and ABC, but are nonethelessrecommendations

• Determine “Best ScienceInformation Available”

And Important role in SEDAR…

What is SEDAR

• Southeast Region method for assessing regional, federal stocks

• Southeast Data, Assessment, and Review– Data Workshop– Assessment Workshop– Review Workshop

• Each step is open and transparent• Exhaustive documentation

DATA< SURVEY

Fishing for Science is not like fishing for fun or money!!!

Page 14: SEDAR - GMRI.org...S E SEDAR Magnuson‐Stevens Act • Originally Passed in 1976 – 200 mile Exclusive Economic Zone – Regional Council system to manage the resources – Capitalization

• Population:  the entire group about which information is desired.

• Sample:  a representative portion or part of the population.

POPULATION AND SAMPLE

Sampling a population is like taste‐testing soup; one random spoonful can reflect the taste of the whole bowl…

if the soup is well stirred.

Page 15: SEDAR - GMRI.org...S E SEDAR Magnuson‐Stevens Act • Originally Passed in 1976 – 200 mile Exclusive Economic Zone – Regional Council system to manage the resources – Capitalization

GOAL: STATISTICAL INFERENCE AND ESTIMATES

• Drawing conclusions based on data.

• The goal is to use information collected from a sample to try to describe the entire population.

• For process to work PROPERLY, must meet certain scientific criteria

The sample needs to be representative of the population!   Populations are 

seldom ‘well stirred’ !!!

Samples collected for the Survey, now what?

• Goal: estimate a parameter to support inference from Samples

• Parameter is just the thing measured• The estimate has two parts:  Point value and uncertainty (margin of error).

TYPES OF FISHERIES DATA

• Fishery‐Dependent: are derived from the commercial or recreational fisheries. 

• Fishery‐Independent: are collected directly by scientists, i.e., derived from activities that do not involve the commercial or recreational fisheries.

Why do we need both?   Is one “better” than the other?
