I am imaging a trail of belly-up fish following it out to sea.

“am imaging a trail of belly-up fish following it out to sea.”

On dive boat trips, we used to see long trails of brown sludge offshore Hawaii after cruise ships had transited the area. The crew would always be dodgy about the sludge if asked.

I suspect the treatment is only used in coastal areas closer to land.

Just the opposite. The ships use maceraters to grind up and discharge food waste with grey water. Sharks and fish follow the cruise ships.
