Carcass feeding as a cryptic foraging mode in round goby Neogobius melanostomus

J Fish Biol. 2015 Jul;87(1):194-9. doi: 10.1111/jfb.12708. Epub 2015 May 25.

Abstract

Round gobies Neogobius melanostomus were observed readily consuming soft tissue from carcasses of larger fishes under both laboratory and field conditions. Consumption normally progressed in a typical sequence, starting with soft and easily accessible tissues such as the eyes, followed by puncture of the abdominal cavity, gut consumption and then muscle consumption. Carcass feeding has not previously been seen in N. melanostomus and has potential consequences for transfer of nutrients and contaminants.
