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.
Blue catfish are by far the largest species of North American catfish. The previous Florida record was held by James Mitchell, who caught a 64.5-pound catfish also from the Choctawhatchee River in 2008. For comparison, the International Game Fish Association lists a 143-pound blue catfish from Virginia as the world record.
