IMHO your last stanza greatly weakens the entire poem with the stilted sentence construction in the first and last lines.
"It has fish that do swim
It ?s current does flow
Fishermen to fish
And boats that do row"
Since you do not keep a consistant meter between stanzas, why not try something like:
"It has fish that swim
And currents that flow
Fishermen to fish
And boats to row"
