Hey...here's something:

"Atlantic Salmon: The true salmon, the largest members of the salmon family, are characterized by tasty flesh that is often orange-red. The common salmon of the North Atlantic Ocean is Salmo salar (most other fishes in the genus Salmo are called trout). Atlantic salmon sent to market average about 7 kg (about 15 lb) in weight, but specimens weighing more than 45 kg (more than 100 lb) have been caught. The Atlantic salmon migrates to cold, fresh water in late spring or early summer, swimming upstr eam at an average rate of up to 6.4 km (4 mi) per day. Because salmon can jump as much as 3.7 m (12 ft) out of water, they clear most obstacles in their path. The female lays as many as 20,000 eggs in October or November, after which time the adult salmon float downstream and return to the sea. "
