Eventually, due to their hunger and the dire nature of their situation, Ash and Brock began to discuss and fantasize about eating James's Magikarp. Unfortunately for them and Meowth in particular, Magikarp's body composition renders it nearly inedible. Misty elaborates on this, stating that Magikarp are nothing more than scale and bone, thus there would be little sustenance obtained.
It is possible, based on wording used in Cherubi's Pokédex entry, that humans, not just Pokémon have eaten Cherubi's ball-like appendage before. Also, according to its Pokémon Black 2 and White 2 Pokédex entry, Basculin are remarkably tasty, indicating humans have eaten them as well. Pokémon Silver's entry states that Seadra's fins and bones are used in herbal medicine. According to Pokémon Moon's Crabrawler's entry, its pincers aren't meaty, but rich in nutrients and considered delicious. Crawdaunt's entry in Ultra Moon says that its claws aren't delicious at all in contrary to Crabrawler and Clauncher's. Likewise, in Pokemon Sword's entry for Barraskewda, it is heavily implied that they have been eaten before, noting their "surprisingly tasty" flesh.
