What is the author's style in The Milkfish Gatherers by James Fenton?

The Milkfish Gatherers is written in quatrains, end-rhymed perfectly in lines two and four of each stanza. Rhymes articulate a resonance among vowels or words that seem to echo previous vowels or words. This echoing results in a pattern of aural effects. The rhyming of lines two and four lulls the poem as if at sea. Later, the first line will repeat, heightening the wave effect.
