Does fishing traumatize fish?

Fishing doesn’t only hurt fish. Millions of birds, turtles, and other animals sustain debilitating injuries after they swallow hooks or become entangled in fishing lines. Wildlife rehabilitators say that discarded fishing tackle is one of the greatest threats to aquatic animals.

Do fish have brains?

Yes, they do have brains. Fish are much more intelligent than we can ever think of them. Their brain helps them react as per the situation they face. For their survival in the aqua world, fish’s brain helps them take all the necessary actions.
