Catching and releasing when fishing

I went fishing recently and before catching any fish I did not have a clear intention whether I would catch and release the fish or eat it. When I had the fish already hooked on the line I was told that we should eat it by 1 person so I pulled it out and thought we were going to eat it. But then another person more knowledgeable told me to release it back into the ocean because the fish was a bottom feeder and would not be nice to eat. I then released the fish back into the ocean after it had already been hurt by the hook. I did not know that it is not good to catch and release before fishing. Did I commit a sin by catching and releasing that fish?
