On the one hand, it is true that animals suffer very much when they are killed, and some of their deaths are really cruel. In addition, we eat lots and lots of meat and fish, and derivative products, which means many animal deaths. Nevertheless, we can and we must eat plants too (fruits, vegetables), so we can let animals live happily and have a healthy good live, without causing so much pain by just eating plants and having vitamins to make up for the meat. We would not like to be haunted and eaten, so we should not do it to the other animals.
To sum up, I do not believe that eating meat is morally wrong. As many other animals, we need it too, and I do not find anything wrong about it. Meat and fish are healthy and necessary, and delicious too.
