Assume there is a certain population of fish in a pond whose growth is described by the logistic equation. It is estimated that the carrying capacity for the pond is 1100 fish. Absent constraints, the population would grow by 210% per year. If the starting population is given by p0 = 400, then after one breeding season the population of the pond is given by: (find each)
p1=
p2=

Part B Please!!
Scenario The population of fish in a fishery has a growth rate that is proportional to its size when the population is small. However, the fishery has a fixed capacity and the growth rate will be negative if the population exceeds that capacity. A. Formulate a differential equation for the population of fish described in the scenario, defining all parameters and variables. 1. Explain why the differential equation models both condition in the scenario. t time a...

It has been found that when a certain type of fish is living in a pond its population increases by 25% every year (a) The pond had 2000 fish when records began at the end of year 1. What was the size of the population at the end of year 3? ( b) Fishing was allowed from year 4 onwards, and it has been estimated that fish were taken every year. Write an equation that describes the size of the...
