In population ecology and economics, optimum sustainable yield is the level of effort (LOE) that maximizes the difference between total revenue and total cost. Or, where marginal revenue equals marginal cost. This level of effort maximizes the economic profit, or rent, of the resource being utilized. It usually corresponds to an effort level lower than that of maximum sustainable yield. In environmental science, optimum sustainable yield is the largest economical yield of a renewable resource achievable over a long time period without decreasing the ability of the population or its environment to support the continuation of this level of yield.

Famous quotes containing the words optimum and/or yield:
“Everywhere—all over Africa and South America ... you see these suburbs springing up. They represent the optimum of what people want. There’s a certain sort of logic leading towards these immaculate suburbs. And they’re terrifying, because they are the death of the soul.... This is the prison this planet is being turned into.”
—J.G. (James Graham)
“You oughtn’t to yield to temptation.
Well, somebody must, or the thing becomes absurd.”
—Anthony Hope (1863–1933)
