When you find plastic inside a fish, can you tell how long it’s been there?

I asked Zora McGinnis this question.  One of her projects aboard is to dissect the fish we catch during the cruise and look in their guts for plastic ingestion.  She said it is not possible to tell how long the plastic has been inside the fish.
