Besides these conservation issues, Jonathan Balcombe, ecologist and author of “What a Fish Knows,” told The Dodo that it’s important to remember that fish like the bluefin tuna are fellow animals and sentient beings — and this raises ethical concerns about overfishing and eating them.
“If people have trouble relating to fish, it’s probably because [fish] are really out of view,” Balcombe said. “They evolved in another realm — they’re below the surface of the water. We look out over an ocean or a lake and we don’t see them, so we’ve been really alienated from them through history. Most of our contact with them is when they’re floundering around dying, gasping on land after we catch them.”
