A fish population has a per capita birth rate of 10 young per fish and a per capita death rate of 0.3 (= 30% chance of dying). Its carrying capacity is 50,000. What should be your harvest rate if you want to maximize your catch (number of fish) sustainably, i.e. without risk of bringing the population to extinction? Show your calculations. Note that there is no variation in this system.
