Assume that a population of tuna is at K. To provide maximum sustainable yield, how would you recommend that fishermen should harvest this population, and why?

A. Harvest down to maximum sustainable yield (where the slope of the growth curve is the smallest); this allows the population to be renewed the fastest because it has the maximum per capita growth rate.

B. Take one small harvest then allow the population to recover quickly; this minimizes the number of individuals removed from the population.

C. Harvest down to maximum sustainable yield (where the slope of the growth curve is the steepest); this allows the population to be renewed the fastest because it has the maximum population growth rate.

D. Take one large harvest then allow the population to recover slowly; this minimizes the effects of fishing on the population over time.
