How does the poet use alliteration in the poem, The Milkfish Gatherers?

Alliteration begins "The Milkfish Gatherers" with "The sea sounds insincere." The repetition of consonant sounds, the s, heightens the sinister sense of the poem. Alliteration is one of the principal devices of melopoeia, which is the aural and musical quality of language. The s is used most repetitively in "The Milkfish Gatherers" to draw attention to "the setting sun behind the Sierra Madre" and the insect-shark "bursting its skin." The s is the sizzle of the sun hitting dusk's dew and the blood sliding from the veins of the highbred creature. Alliteration adds texture to the text and is invaluable in setting the scene.
