At , a slightly higher harvest rate, however there is only one equilibrium point (at ), which is the population size that produces the maximum growth rate. With logistic growth, this point, called the maximum sustainable yield, is where the population size is half the carrying capacity (or N = K 2 {\displaystyle N={\frac {K}{2}}} ).
Sustainable yield is the amount of a resource that humans can harvest without over-harvesting or damaging a potentially renewable resource. [1]In more formal terms, the sustainable yield of natural capital is the ecological yield that can be extracted without reducing the base of capital itself, i.e. the surplus required to maintain ecosystem services at the same or increasing level over time.

Here f(N) captures any change in the prey population not due to predator activity including inherent birth and death rates. The per capita effect of predators on the prey population (the harvest rate) is modeled by a function g which is a function of the ratio N / P of prey to predators.

In agriculture, custom harvesting or custom combining is the business of harvesting of crops for others. Custom harvesters usually own their own combines and work for the same farms every harvest season. Custom harvesting relieves farmers from having to invest capital in expensive equipment while at the same time maximizing the machinery's use ...
A short period of excess mortality that is followed by a compensating period of mortality deficit (i.e., fewer deaths than expected, because those people have died at a younger age) is quite common, and is also known as "harvesting". Mortality deficit in a particular time period can be caused by deaths displaced to an earlier time (due to ...
