First off, since 2000, catfish and tilapia rank as two of the most popular fish consumed in the United States thanks mainly to their taste and relatively low expense. And both contain heart-healthy omega-3 fatty acids.
Elevations and depths of the Great Lakes are shown by a profile in figure 41.6. Superior has the greatest depth, 1330 ft (370m); Michigan, Huron, and Ontario are of moderate depths, 800 to 900 ft (240 to 275 m); while by comparison Erie is very shallow, 200 ft (60 m).
This lake is the smallest of all the Great Lakes when measured in surface area (7,340 square miles / 18,960 square km). While it is similar in width and length to Lake Erie, it is much deeper and holds about four times the water volume (393 cubic miles/1,640 cubic km).
