Abstract

While there is increasing moral consideration for terrestrial vertebrate non-human animals (mammals and birds), little to no consideration is granted to aquatic animals (fish, cephalopods, and crustaceans). These animals are even often overlooked by the animal rights movement, despite constituting the majority of victims in animal production and consumption, with estimates ranging from 94 to 98%. Every year, between 1 and 3 trillion aquatic animals are killed worldwide. This article aims to highlight, based on recent neuroscientific and ethological advances, that aquatic animals are capable of feeling pain and are sentient, thus capable of experiencing conscious negative mental states. This relatively recent knowledge allows us to examine critically the ethical implications of practices such as fishing and fish farming, as well as the cultural representations that underpin them.
