Connecticut in the United States.

Two counts, two questions. 105 is the number of species observed in Connecticut and filed with GBIF, which includes lakes, the coast, and museum records. 59 is the number the USGS stream survey caught, which samples flowing fresh water only. Neither is the other, so the site never adds them.

A state fish is a statute, not a survey. It says which fish the legislature chose, not which fish is most common. The list above links each row to the state's own record.
