salmon
Swimming upstream is to do something the hard way. It is more difficult to swim against the current. Salmon swim upstream in order to spawn.
Trout typically swim upstream during their spawning season, which varies by species and location but generally occurs in the spring or fall. For example, many species of salmon trout migrate upstream in late summer to early fall to spawn. In colder regions, some trout may spawn in late spring. The exact timing can depend on water temperature and environmental conditions.
The fish that swims against the flow of water is called a salmon. They migrate upstream to spawn and their ability to swim against strong currents is due to their strong muscular bodies and specialized physiology.

Thats how they swim
they swim
Salmon swim upstream to live out their adult lives. The thing that helps them to swim upstream is purely will power and instinct. They are taught all of their lives to swim to the ocean when they are adults and return to the river where they were born to give birth and die.
A koi would generally be depicted swimming upstream, not down. According to Japanese legend, once a koi swims over the falls at the 'Dragon Gate on the Yellow River' it would be transformed into a dragon. As such, the koi swimming upstream is a symbol of Ambition.
The Pacific Bluefin Tuna does!
