Question

When modeling fisheries: (You may choose one or more answers)

A. Fixed quota models result in multiple maximum sustainable yield population levels
B. Fixed effort models result in an inability to harvest at maximum sustainable yield
C. Fixed quota models are risky because slight miscalculations can result in fish population extinction
D .Fixed effort harvesting reduces the risk of population extinction

Answer 1

Option A, Fixed quota models are risky because slight miscalculations can result in fish population extinction

Explanation:

Some of the major drawbacks of modelling fishing are as follows –

a) The fixed quota model is very risky as a miniscule change in attributes can result into extinction of fish.

b) On the other hand fixed effort harvesting can decrease the risk of fish population extinction

Hence, option A is correct
