What will be a good topic in describing the poem "The Fish" by Elizabeth Bishop"

A good topic
to treat Bishop's "" with is transformation.

The fish doesn't
fight with the speaker, and the speaker doesn't think much of it to begin with.  She goes
through and relates an unemotional, objective description of the fish which includes faded
skin, lice infestation, bloody gills, and even the fish's entrails:  hardly a flattering
depiction...
