From the NEWSWIRE article, "Catfish Farmers Feel Forced Out of Business", the expected economic profit from the catfish market: Is enough to attract entry.

The law of diminishing returns helps to explain why: Marginal cost increases, in the short run, as more output is produced. The demand curve for a competitive firm is perfectly elastic. The total cost curve diminishes as long as output increases. Marginal cost decreases as more output is produced.

One large firm supplies the entire product to the market
