This is a follow-up to my previous question (Fische springen). Is There Another Way to (Poetically) Say "Sie ist schön?" Does springen mean "spring," "jump," or both? What are some other English equivalents? (In the linked poem, it was used in a context (Fische springen), that I would not have guessed.)
Springen means to jump, not spring, that would be Frühling or Quelle.
"The fish are jumping" shouldn't be translated with "die Fische springen", it would be "die Fische beißen". But many germans will try to translate it this way, because they don't know the english saying, so they will be thinking of fish literally jumping, like salmon.
With eel you can say "Der Aal läuft gut" meaning the eel bite. All other fishes you just say "die Fische beißen" (not "... beißen gut", if they bite thats already good).
"Springen" means "jump", and the correspondence is very good for lots of idioms.
"Springen" is etymological related to the meanings of the English word "spring", but it does not have the current meanings of the English word.
If you want a better answer, you should make your question much more precise.
