Maximum sustainable yield

Maximum sustainable yield is determined by

• the government

• scientists

• fishermen

• none of these

A fish stock has a carrying capacity of 1000. What is the maximum sustainable yield?

• 1000

• 800

• 500

• 100

MSY is shown at letter

Points of zero yield are shown at letter(s)

• A only

• B and C

• D and E

Choose the correct order of determining numbers for effective fisheries management.

• TAC -> quotas -> MSY -> estimate population

• estimate population -> quotas -> MSY -> TAC

• estimate population -> MSY -> Quotas -> TAC

• estimate population -> MSY-> TAC-> Quotas

Who determines the TAC?

• the government

• scientists

• fishermen

• none of these

The shape of a carrying capacity graph is

• linear

• exponential

• logistic

• parabolic

The TAC should be

• more than the MSY

• less than the MSY

• equal to the MSY

• zero
