There are some Pokédex entries on it too. I remember one where Pelipper could scoop up 40 Wishiwashi at once.There's that age-old debate of whether people in the Pokémon world eat Pokémon like we do with animals in the real world. I think it's been shown in the anime a few times, like in the episode on the SS Anne where a fantasy shows plates of chopped Magikarp.
Although that might be pretty freaky in some cases; would people eat KFC - Kentucky Fried Combusken?
(By the way, I've changed the thread title so that it includes scary or weird stuff in the manga and anime as well as the games.)
