Common Mistakes to Avoid
The most frequent error learners make is adding an "s" to the word "smelt." While it is tempting to say "smelts," the standard plural form remains "smelt." Additionally, ensure you use the full name "rainbow smelt" rather than just "smelt," as "smelt" is a broad family name that includes many different species. Being specific helps others know exactly which type of fish you are discussing.
