What Is The Rarest Trout Species?

Every trout lover wants a Paiute cutthroat in the table, but very few can get that.

Paiute cutthroat is the rarest trout of the world. Paiute is found in a nine-mile stretch of Silver King Creek, the main tributary of the Carson River in the Sierra Nevada in California.

Maybe it’s every trout fisherman’s dream that he will catch a Paiute cutthroat someday.

Characteristics of the Paiute Cutthroat

Usually, there are Paiute with three specific colors. These are copper, green and pink. Paiute trout was named this because under the jaw of every Paiute, there is a red-orange slash. This slash also indicates the par marks of adulthood. There are few spots on the body of almost every Paiute.

These spots usually located above the lateral line. The length of a Paiute is rarely more than 25 cm. the productivity rate of the Paiutes is very low. The largest Paiute ever caught was 18inch in length and 1.1 kilograms in weight. The habitat of the Paiute is the smallest among all the salmon species of North America. This is why the Paiute is the rarest trout in the world.

Behaviors of Paiute Cutthroat

A Paiute become matured at the age of two and most of the Paiute lives 4-6 years. 4 years is the mean life expectancy of the Paiutes. Those who live more, are expected to be lived for 6 years. Over the lifetime of a Paiute, it can spawn successfully only two or three times.

Adult Paiutes usually spawn in the flowing waters. How many eggs a Paiute will produce depends on the size of its body. If a female Paiute is 20 cm, it will produce 250 t0 400 eggs at a time.

A successful reproduction of Paiutes takes three months. Spawning usually takes place in July and it takes September and October for eggs to hatch. Paiutes don’t usually go far from their area. The adult Paiutes defend the territory from other species.

Genetics of the Paiute

Though Paiute cutthroat is the rarest trout of the world, they are genetically very close to the Lahontan cutthroats. Lahontan cutthroats of the independent lake share the most genetic similarities with the Paiute cutthroats. Paiute cutthroat is the least genetically diverse population.

The abundance of Paiute Cutthroat

The population of Paiute cutthroat declined in the last few years. The reason behind this was reduced streamflows and ice. There are a very small number of Paiutes remaining but they can’t interbreed. Currently, there are Paiute in around nine streams. These are the stable Paiutes. Each of the nine streams supports Paiutes between 400 and 700. By interbreeding with the rainbow trout in the early twenty century, we eliminated the Paiutes from their ranges.

Threats to Paiutes Cutthroat

The Paiute faces the largest threats from the non-native fishes. The Paiutes have a limited distribution that makes it harder for this species to increase their population. Moreover, interbreeding and competition have added more dimension to their threats of extinction.

To keep the Paiute safe from this threat, the USFWS combining with the California Wildlife authority working. They are trying to reduce the number of non-native fishes by applying fish-killing chemicals.

We started with the discussion of how much we love to eat trout and how eagerly we desire for a Paiute on our dinner table. The trout fishermen also want to catch a Paiute and it will certainly make them happy.

But these are not more important than saving a species from extinction. This beautiful creature, a beautiful trout is on the verge of extinction. After this much discussion, I hope we are now aware of the Paiutes. Obviously we will eat Paiute cutthroats, before that we will provide them with the opportunity to grow.
