If too many of a certain species of game fish are caught,the population will crash and future years of fishing in the lake will suffer.Your job as a fisheries and wildlife officer is to decide how many fish you should allow to be harvested so as to sustain the sport fishing industry while maintaining the fish population.Assuming the fish population normally experiences logistic population growth,which of the following options would seem to make the most sense in managing this fish population?

Allowing harvesting to a level of half of the species' carrying capacity would ensure that the fish population does not crash while still allowing for sustained sport fishing. This approach would keep the fish population at a healthy level while also allowing for some harvesting that can benefit the sport fishing industry. Allowing harvesting only above the species' carrying capacity (B) or to the full carrying capacity (C) would be too risky and could lead to a population crash. Allowing harvesting to a level of 1/10 of the species' carrying capacity (D) would be too conservative and could limit the potential benefits for the sport fishing industry.
