15-minute trip from Seattle

Because of water level differences between fresh water and sea water, Ballard Locks give the ships a way to cross from Lake Washington to the Puget Sound and vice versa.

It is also a place to witness the remarkable journey of salmons that swim upstream from the ocean (hundreds or thousands of miles away) to the lakes and rivers to spawn. After growing from eggs into young salmons, they instinctively go back to the ocean by reversely swimming through this canal and will come back to the same place to breed when they mature. The same process is repeated, known as the Salmon circle of life.

Hmmm Salmons...my favorite sushi. They sure don't look as good as they taste.

Almost the same process applies to Cambodian Cat fishes or Trey Pra.They breed and laid eggs upstream the Mekong river, north of Kratie province.When the eggs grows into very samll young babies, they all swim down the Mekong river until Vietnam and spread in the Tonle Sap lake and others Mekong affluents.
You can raise them in the pond, they grow fast if well fed, but never breed except at the upper Mekong river.
