CFP CFP Fish Population Dynamics & Stock Assessment 2

Question 1

Which statistical method is commonly used to estimate population size using mark-recapture data?

Accepted Answer

Chapman modification of the Lincoln-Petersen estimator

Answer

The Chapman modification of the Lincoln-Petersen estimator is a standard mark-recapture formula used to estimate closed population size.

Question 2

In fisheries, what does the term 'F_MSY' represent?

Accepted Answer

The fishing mortality rate that produces maximum sustainable yield

Answer

F_MSY is the level of fishing mortality at which the stock produces its maximum sustainable yield.

Question 3

What is an age-structured population model primarily used for in fisheries management?

Accepted Answer

Projecting future population size and yield under different harvest scenarios

Answer

Age-structured models project how fish populations will change over time under various fishing pressures by accounting for survival and growth by age class.

Question 4

What is the primary purpose of a spawning stock biomass (SSB) reference point?

Accepted Answer

To set a threshold below which the reproductive capacity of the stock may be compromised

Answer

SSB reference points define a minimum reproductive biomass level needed to maintain adequate recruitment and long-term stock viability.

Question 5

Which tool is widely used by US federal fisheries scientists to conduct integrated stock assessments?

Accepted Answer

Stock Synthesis (SS3)

Answer

Stock Synthesis (SS3) is an age- and length-structured statistical stock assessment model widely used by NOAA and other US fisheries agencies.
