Catch and Release - in the fishing world means to return a fish that has been reeled in back to the water.
CPR (catch, picture, release) - in the fishing world means to return a fish that has been reeled in and then photographed back to the water.
The term "Practice Catch & Release" is most often spoke in the noun sense. It's an idea.
We like to focus more on the verb description of "practice" and sharpen our skills as best we can.
CPR requires good Catch & Release skills along with camera technique to return the fish to water in a fast manner.
I believe both of these practices (C&R, CPR) are an Art form.
Not all of us are going to be at the same skill level of the Art but we learn and practice to sharpen our skills of the Practice as we go.
I believe the wording should go.......Practicing the Art of Catch & Release or Practicing the Art of CPR.
