Etymology

The first reference to the term "rough" as applied to fish species is in the historical work ''A History of Fish and Fishing on the Upper Mississippi River'' by Carlander. To summarize: In the mid-to-late

19th century The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolis ...

s, and would then travel many miles up or down river to deliver these fish to markets for sale. In hot summer weather, the slow, heavily loaded boats often had to be lightened quickly to ensure that the entire catch did not become spoiled before reaching the markets. The common practice of the time was to save the fully processed fish, since these commanded a higher price at market. Rough-dressed fish (or fish sold "in the rough" — which means they had the

Thus, originally a "rough fish" was a fish of any species that had been only partly processed and which could not be sold for full price. The term subsequently evolved into a derogatory term for any fish that was undesirable or unpopular.
