Congratulations, but instead googling the minimum to confirm your side, maybe Google "majority vs plurality" and get back to me.

Majority has multiple definitions, a simple, inexact definition in common English, and a more exact definition in poli-sci, math, and engineering.

Of course, all of this is an irrelevant aside since as op clarified, fishing equipment constitutes over 50% of the trash, making it the majority by any definition.

Its also irrelevant because using context clues you can easily see OP meant majority in the sense of the largest number of the group.
