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.

INTERPRET DATA Examine the top and middle graphs in Figure 54-5. Are these examples of exponential or logistic population growth? Where is K in each graph? (You may need to refer to Chapter 53 to answer these questions.) RESULTS AND CONCLUSION: The top and middle graphs show how each species of Paramecium flourishes when grown alone. The bottom graph shows how they grow together, in competition with each other. In a mixed culture, P. aurelia outcompetes P. caudatum, resulting in competitive exclusion. SOURCE: Adapted from G.F. Gause, The Struggle for Existence (Williams and Wilkins, Baltimore, 1934). Figure 54-5 G.F. Gauses classic experiment on interspecific competition

The carrying capacity of seals would decrease, as would the seal population. The carrying capacity of seals would decrease, but the seal population would remain the same. The number of seal deaths would increase but the number of births would also increase, so the population size would remain the same. The carrying capacity of seals would remain the same, but the population of seals would decrease.
