Can you eat Koi fish?

Yes, you can eat koi fish, but you may not want to. Koi fish reside in the freshwater and mostly all freshwater fish are safe to consume but it is most likely that you can not bear the taste and the smell of the koi fish.

What is a Koi fish?

Koi fish, scientifically known as Cyprinus rubrofuscus, is a very common pet variety for indoor and outdoor fishponds all over the world for centuries.

Koi fish have an exceptional life span for a fish. They tend to live for approximately 70 years when kept as a pet. However, in nature, they have an average life span of around 30 to 40 years. Koi fish have a length of nearly 25 cm and a weight of 160 g.

Koi fish are extremely valued for their spiritual and cultural importance across different cultures, usually symbolizing peace, harmony, and prosperity. They are the descendants of the common carp, Cyprinus carpio. However, koi meat is not like the common carp, rather it is quite hard. 

Like all carps, koi fishes are bottom-feeders that feed upon a wide variety including algae, plants, crawfish, insects, and worms. They also feed upon aquatic grasses, giving these fishes easy existence where predators do not swarm.

They tolerate low levels of oxygen well, which allow them to dominate the food chain in standing waters where other species simply can not survive. They can also inhale air directly from the surface, providing them with a huge edge over other fishes.

Koi fishes are residents of temperate waters, they prefer temperature ranges between 59 °F to 77 °F. Under 50 °F, their immune system starts to suffer, making them more prone to diseases and parasitic infections. They can often survive beneath the ice provided that water is available. 

Koi fish spend most of their life span in standing and shallow water, so there is a possibility of bacterial infection from consuming raw koi fish. So, if you desire to eat koi fish, then you have to cook it thoroughly with adequate heat. In addition, koi fish sometimes may be given chemicals for breeding colourful and attractive varieties that can be dangerous to the human body.
