True but they do have extremely Loud ear bursting sonar pulsing in the oceans all day, lots of extremely loud Motors and other random loud noises that humans make, tons of netting and plastic bags and random pieces of plastic that are really shiny and look like pieces of food, lots of clouds of toxic poisonous ammonia and oil and Industrial chemicals and dyes, an environment that's heating up uncomfortably, becoming less oxygenated, and generally less hospitable.. I can't assume that fish are too happy anymore at all
