For the last centuries, we were thinking that fish cannot feel pain. The latest research shows that we were wrong. Fish, like other mammals, do feel pain.

In the angler's world, it is believed that catch-and-release fishing does not cause any harm to the animal. That is not true. Fish suffocate when they are ripped from their environment. The trauma is so intense that some of them cannot handle the change in pressure, causing their internal organs to burst. Fish are left permanently wounded from hooks or later suffer a slow and painful death. A recent study found that hook injuries from catch-and-release fishing inhibit suction feeder fish's ability to eat and reduces their likelihood of survival. Putting a hook through a fish's lip is considered "normal" but putting a hook through a cat or dog lip would be considered animal cruelty. Fish cannot demonstrate their ability to suffer like cat or dog, cannot express the pain in the way that we would understand that. Fish cannot scream. 

Aquatic animals account for the highest number of animals killed for food, between 1.2 trillion to 2.7 trillion yearly. Aside from their use as food, these creatures are killed in a wide variety of additional ways: for entertainment, as medicine, in research and testing. I believe that every animal deserves respect and freedom of living its own life. Man has polluted and caused enormous destruction in the aquatic environment, as a result of which, many fish lost their lives. The current situation forces us to critical analyse socially accepted practices. In the 21st century, no animal should suffer as the reason of man's entertainment.
