I think there should be a route 53 but with water pokemon! To use
it you need to find/buy maps and go to route 53 then by the honey
tree there would be a net lake which you can cast your net out and
wait like honey. Unlike the honey tree you can set out 1 at a time
and they will be stuck until you return. To find nets, go to rumble
areas or buy them in the store. You still need to use poke balls to
catch the pokemon and catchable pokemon are pokemon like magikarp,
krabby, basculin, etc
