We find in this story some of what we already suspected, but never had documentation for previously. We find that in some ways the problems of fish are bigger than even those of other animal agriculture. A line and a hook is murder on fish, one at a time. It's no longer hit or miss to find a net-full. In addition, today's fisherman is able to purchase satellite maps that chart weather conditions and water temperature, predicting the movement of fish.
Vessels are able to be at sea for months.
No longer are fishermen inconvenienced by rotting fish on board ship having to rush back to shore. One in every 4 animals taken from the sea is unwanted and then discarded dead overboard. The solutions, unfortunately, are often just as bad as the original problem. On the contrary. Aquaculture is often the cause of even more disruption to the environment.
