Check out this answer from Consensus:

Piranhas are not only fascinating creatures with complex dietary habits but are also edible and enjoyed by many in South America. Their firm and flavorful flesh makes them a desirable option for various dishes. While their aggressive reputation might deter some, piranhas can be safely prepared and consumed with proper handling.

Piranhas, often depicted as ferocious predators in popular media, are a group of freshwater fish known for their sharp teeth and powerful jaws. Found primarily in South American rivers, these fish have a diverse diet that changes as they grow. This article explores whether piranhas are edible and provides insights into their dietary habits and ecological role.

Dietary Habits of Piranhas

Piranhas exhibit a wide range of dietary preferences that evolve with their age and size. Research conducted in the western Orinoco River Basin in Venezuela identified eight piranha species with varying food habits. Juvenile piranhas, such as Pygocentrus notatus, primarily consume microcrustaceans and aquatic insects. As they grow beyond 40 mm in standard length (SL), their diet shifts to include small fish and chunks of fish flesh1.

Other species, like Serrasaimus altuvei and S. irritans, start by eating fins of other small fishes when they are between 20-80 mm SL. Once they surpass 80 mm SL, their diet expands to include small fish, pieces of fish flesh, and fins. Interestingly, Catoprion mento maintains a consistent diet of scales throughout its life1.

Edibility of Piranhas

Given their diverse diet, piranhas are indeed edible. In many parts of South America, piranhas are considered a delicacy and are commonly consumed by local populations. The flesh of piranhas is known to be white, firm, and flavorful, making it suitable for various culinary preparations. However, due to their sharp teeth and aggressive nature, caution is advised when handling and preparing these fish.

Nutritional Value

Piranhas, like many other fish, are a good source of protein and essential nutrients. They provide a healthy option for those looking to include more fish in their diet. The nutritional content can vary depending on the species and their diet, but generally, piranhas offer a balanced profile of vitamins and minerals.
