Do fish feel pain when it gets hooked?

Here are two apposing views.

The world's foremost expert on the subject is Dr. James D. Rose of the University of Wyoming. He's spent 30 years working on questions of neurology, examining data on the responses of animals to painful stimuli. In 2003 Rose published a landmark study in the journal Reviews of Fisheries Science, concluding that animals need specific regions of the cerebral cortex in order to feel pain. And fish do not have them.

Apposing view

It is a well common known fact that fish indeed feel pain when they are about to die. Fish just like humans fear the unknown, such as dying. Even though they have very small organs, it still causes them great pain why they are about to let go. Also it is known that fish actually dread being flushed down the toilet, this is because more than once a fish actually hasn't been dead before it has been flushed. Remember, be nice to your fish.
