Top Costly Fish Types

While these aquatic creatures are priced higher than your average goldfish, these top luxury fish are a splendid sight to behold. Listed below are the highest-ranking pricey fish, to acquire or farm, in the world:

17. Golden Trout

This is a bit of an unusual one, as the Golden Trout is one of the most expensive fish in the popular Animal Crossing video game! You can exchange this fish for 15,000 bells.

Located in the upper mountain rivers of California, the Golden Trout is quite the catch of the day. This fish is easily identifiable by its coloring, a golden appearance with black dots and red stripes.

16. Zebra Pleco

Also known as Hypancistrus zebra, this species of freshwater catfish originates from the Xingu River in Brazil. It is highly prized by aquarium hobbyists for its distinct black and white striped pattern and relatively small size.

Endangered in the wild, zebra plecos offered for sale are tank-bred. The high demand and limited supply together with their unique appearance, drives up their price.

In general, prices for zebra plecos can range from $200-$500 or more for a single fish, depending on size and quality.

15. Whale Shark

Known as the largest fish in the world, the humble Whale Shark reaches more than 40 feet in length. An endangered species, Whale Sharks are illegal to fish for their meat and fins. This unfortunately makes them highly valuable on the black market.

Tip: If you find yourself in Cancún, be sure to go on an interactive Whale Shark encounter and swim with these gentle giants for an unforgettable experience.

14. Sawfish

The carpenter of the sea, this handy fish has the appearance of a saw-like structure on its snout, edged with various size sharp teeth. The saw fish is not to be confused with the saw shark, which has a different type of saw and replaceable teeth.

While they may be a danger to nearby prey with their terrorizing tool, Sawfish are quite harmless to humans. It is illegal to trade sawfish, since the species is at risk of extinction.

Sawfish can only be sent to aquariums for the purpose of conservation. Unfortunately, there is illegal hunting for their snout, meat, and fins.

13. Bluefin Tuna

While this tasty fish is often found on your ordinary sushi platter, there are quite a few different types of tuna. Found mainly in the Western Pacific Ocean, a single Pacific Bluefin tuna fish can sell for hundreds of thousands of dollars in Asia.

However, over-fishing and catching bluefins before they have reached maturity is depleting the species. Minimum catch size limits are needed to protect the Pacific Bluefin.

Japanese tycoon Kiyoshi Kimura paid $3.1m for a bluefin tuna weighing 278kg at an auction in Tokyo’s fish market. He owns the Sushi Zanmai restaurant chain.

The Yellowfin tuna is not currently classed as endangered. This fish species is very important due to its commercial market value. For example, a Barbados tuna fishery is said to make an additional 2 million dollar profit annually thanks to this special fish.
