Question 1

Which stock assessment model assumes that a fish population's growth follows a logistic curve and that maximum sustainable yield occurs at half the carrying capacity?

Accepted Answer

Schaefer surplus production model

Answer

The Schaefer surplus production model uses logistic population growth, predicting MSY at B = K/2.

Question 2

A fisheries manager notices that the spawning stock biomass has declined below the limit reference point. Which action is MOST appropriate under U.S. federal fisheries law?

Accepted Answer

Implement a rebuilding plan within 2 years

Answer

The Magnuson-Stevens Act requires that a rebuilding plan be implemented within 2 years of a stock being declared overfished.

Question 3

What does the term 'effort creep' refer to in fisheries management?

Accepted Answer

Gradual increase in fishing power that outpaces management measures

Answer

Effort creep occurs when improvements in technology and efficiency increase effective fishing power even when nominal effort stays constant.

Question 4

Which concept describes the minimum population size below which a species is at high risk of extinction due to demographic stochasticity and inbreeding depression?

Accepted Answer

Minimum viable population (MVP)

Answer

Minimum viable population (MVP) is the smallest isolated population that has a specified probability of surviving for a given time period.

Question 5

In the context of ecosystem-based fisheries management (EBFM), what is a 'forage fish'?

Accepted Answer

A small, schooling species that transfers energy from plankton to higher trophic levels

Answer

Forage fish such as anchovies, herring, and menhaden are small schooling species that are critical prey for larger fish, seabirds, and marine mammals.
