Humans were to become lazy and aggressive, a combination which led them into the unfortunate habit of killing animals, birds, fishes, and yes, even one another, for food.
Going Fishing?
Catch-and-release In Less Than Four Minutes, Please.
Science Daily
Recreational fishing that involves catch-and-release may seem like just good fun, and that released fish go on to live happily ever after, but a recent study at the University of Illinois shows that improper handling techniques by anglers can increase the likelihood of released fish being caught by predators.
After the stress of the catch and lack of oxygen from being out of water, the fish is in a weakened state. When it eventually gets released back into the water, if fish haven't been handled properly, they are more likely to be caught by a predator.
A study on the effects of catch-and-release angling on bonefish which was conducted by a team led by University of Illinois researcher Cory Suski.
"Whenever a fish is caught and reeled in, it expends a lot of energy so that's one stressor," said Suski. Depending upon the skill of the angler, the catching can last a long time and put additional stress on the fish. When the fish is brought up on the deck or in the boat to measure and take a picture, it faces an additional challenge and cannot obtain enough oxygen, and the fish continues to accumulate physiological disturbances. "Our recommendation to catch-and-release sport anglers is that they minimize the time it takes to actually land the fish and take a picture, and then get it back into the water as soon as possible."
