The second macroeconomic consideration of increased imports is the impact on exchange rates. As we have shown in the previous section, as U.S. consumers increase their consumption of imports, the supply of dollars in foreign exchange markets rises.
A member of the Ictalurus genus of American catfishes, channel catfish have a top-end size of about 40â50 pounds (18â23 kg). The world record channel catfish weighed 58 pounds, and was taken from the Santee-Cooper Reservoir in South Carolina, on July 7, 1964. Realistically, a channel catfish over 20 lb (9 kg) is a spectacular specimen, and most catfish anglers view a 10-lb (4.5-kg) fish as a very admirable catch.
When it comes to size, channel cats and white cats can't compete with monster blues or flatheads. Channel cats can grow as large as 51 pounds, as the Magnolia State record indicates. However, flathead catfish can exceed 120 pounds. Blue cats can also reach the triple- digit mark. In fact, old records indicate that gigantic blues weighing nearly 400 pounds were pulled from the Mississippi River in the 1800s. No one really knows for certain just how big a catfish will grow.
