Note 2319 — BOOK IX. THE NATURAL HISTORY OF FISHES.

Cuvier says that there are found in the river Padus, or Po, several species of very large sturgeons, and that there is one of these which still bears the name, according to Salvian and Rondelet, of adello and adilo. Aldrovandus, he says, calls it adelo or ladano. This Cuvier takes to be the attilus of Pliny. But, according to Rezzonico, Paulus Jovius denies that the attilus or adelus of the people of Ferrara is of the sturgeon genus; but says that it is so much larger than the sturgeon, and so different in shape, flavour, value, and natural habits, that the names of these two fishes were used proverbially by the people, when they were desirous to signify two objects of totally different nature. Rezzonico remarks, that the name given to it in Ferrara was properly “l’adano,” which became corrupted into “ladano,” and expresses it as his opinion that it was the same with the esox of the Rhine. He also states, that, from the exceeding whiteness of the flesh, the ladano was called by the fishermen, sturione bianco.
