What happens if I pull a fish backwards?
Pulling a fish backwards through the water deprives a fish of oxygen which is not intuitive to most fishermen who want to aid the fish. The best way to oxegenate a fish is to pull it through the water in the forward direction to increase the laminar flow over the gills and optimize 02 saturation.

Do sharks fall asleep?

How do you know if your fish is suffocating?
Signs of Low Oxygen
They will swim less vigorously and even eat less often. As oxygen levels drop further, the fish will begin to show labored breathing and more rapid gill movements as they desperately attempt to get enough oxygen from the water by passing more water over their gills.
Do sharks drown if they stop swimming?

Can salmon swim backwards?
The answer is Yes, most of the fishes can swim in a backward or reverse direction. Although reverse swimming is not frequently seen if you are an ardent aquarist, you might have already witnessed it somewhere.
Can a fish swim in milk?
The differences in acidity and dissolved oxygen, not to mention all of the fat, proteins, carbohydrates, and other minerals in the milk that might clog the creature’s gills, would quickly spell trouble. The animal would likely die within minutes, if not sooner.
Can fishes sleep?
While fish do not sleep in the same way that land mammals sleep, most fish do rest. Research shows that fish may reduce their activity and metabolism while remaining alert to danger.
