In northern China the concept of C&R does not translate. They can not comprehend any idea of fishing without keeping the fish.

In some European countries you must keep and kill every fish you catch.

There are some folks with strong thoughts on the different strains of brown trout. One being more willing to surface feed than the other.

A few will argue that hatchery trout that are fed floating food grow up to be better risers than those fed sinking pellets.

Some cultures thank the fish or other game when they are caught.

And other societies apologize to the fish whether kept or released.
