Fishery Collapse and the American Fertilizer Industry: A Case Study of the Pacific Guano Company

This article focuses on the nineteenth-century fertilizer manufacturer the Pacific Guano Company, and seeks to understand how it adapted its production in response to the collapse of the Maine menhaden fishery in 1879. This collapse devastated the national market for fish scrap, the firm’s primary input. The company managed to maintain relatively consistent fertilizer output throughout this period of uncertainty by embracing new materials and by actively seeking more stable sources of these novel ingredients. Outwardly, the company gave no indications that it was dealing with supply chain disruption, even though it was, at the same time, rapidly rewriting the recipes for its core products. This disconnect demonstrates how generic categories of nature can help a firm adapt to a crisis and how an environmental change as significant as a fishery collapse can be hidden from the public.
