The initial mass of a certain species of fish is 2 million tons. The mass of fish, if left alone, would increase at a rate proportional to the mass, with a proportionality
constant of 5/yr. However, commercial fishing removes fish mass at a constant rate of 12 million tons per year. When will all the fish be gone? If the fishing rate is
changed so that the mass of fish remains constant, what should that rate be?
When will all the fish be gone?
Inco
The fish will all be gone in years.
