Let's break down the problem to find the population growth step-by-step.

1. Calculate Total Population Increase:
- The population increases due to births and immigration.
- Birth rate = 35 (buffalo)
- Immigration = 4 (buffalo)
- Total Population Increase = Births + Immigration = 35 + 4 = 39

2. Calculate Total Population Decrease:
- The population decreases due to deaths and emigration.
- Death rate = 7 (buffalo)
- Emigration = 17 (buffalo)
- Total Population Decrease = Deaths + Emigration = 7 + 17 = 24

3. Calculate Net Population Growth:
- Net Population Growth is the difference between the total population increase and the total population decrease.
- Net Population Growth = Total Population Increase - Total Population Decrease = 39 - 24 = 15

So, let's summarize the results:
- The population increases by 39.
- The population decreases by 24.
- The net population growth is 15.

Therefore, among the given options:
- The population does not increase by 41.
- The population does not decrease by 15.
- The correct statement is: the population increases by 15.
