Aug 23 - Help understanding these song lyrics

So there's this song by Carla Morrison called "Maleza." I really like it and I understand pretty much the whole thing except for one line and it really bugs me every time I listen to it.

You can listen to it here.

The verse goes:

"Regresate a mi! Yo te cuidaré de todo lo malo. Lo bueno pescaré. En tu corazon depositaré todo ese amor que necesitas tener."

What does "Lo bueno pescaré" mean? Something like "I'll fish for the good"?

Thanks for your help!
