The Struggle for Survival: The Critically Endangered Sevan Trout

Nestled in the beautiful Lake Sevan in Armenia, the Sevan Trout (Salmo ischchan) is a unique and fascinating species that is facing the threat of extinction. As one of the few remaining landlocked salmonid species, the Sevan Trout is a symbol of cultural and environmental significance in Armenia. However, due to various environmental and human factors, its population has been declining rapidly, earning it the status of critically endangered.

In this article, we will delve deeper into the world of the Sevan Trout and learn about its distinct features, behavior, and threats, as well as the efforts being made to conserve this precious species

A Solitary Existence

The Sevan Trout is known for its solitary nature, preferring to live and hunt alone rather than in groups. This social behavior is likely due to the fact that they have evolved in a unique, isolated environment, completely cut off from the outside world.

Unlike other fish, the Sevan Trout does not migrate to different bodies of water. It makes its home in Lake Sevan and its tributaries, making it an endemic species.

Aggression During Spawning

One of the most fascinating behaviors exhibited by the Sevan Trout is its aggressive nature during the spawning season. Known to be relatively docile fish, they transform into fierce and territorial creatures during this period.

Their aggression is directed towards other fish and even their own kind, as they fiercely guard their eggs and breeding grounds from potential predators.

A Unique Diet

The Sevan Trout has a diverse diet, which includes insects and small fish. This is in contrast to other trout species, which mostly feed on aquatic invertebrates Snapper.

This unique feeding behavior is believed to be a result of their isolation in Lake Sevan. In order to adapt to the limited food sources available, the Sevan Trout has evolved to consume a wide range of prey, making them formidable predators in their habitat.

Predators and Prey

Despite being skilled hunters, the Sevan Trout also falls prey to various birds, such as gulls and herons, and larger fish, such as the Brown Trout. These predators are able to easily spot the Sevan Trout's symmetrical tail and adipose fin, making it easier for them to catch and consume.

On the other hand, the Sevan Trout feeds on smaller fish and insects, which are abundant in Lake Sevan and its tributaries.

Threats to Survival

The Sevan Trout faces numerous threats to its survival, both environmental and man-made. One of the biggest environmental threats is habitat degradation due to water pollution. With increased human activity around Lake Sevan, the water quality has deteriorated, making it difficult for the Sevan Trout to survive and reproduce.

Another major threat is overfishing. In the past, the Sevan Trout was commercially important, leading to overexploitation of the species. This, combined with habitat destruction, has significantly reduced their population.

Critically Endangered Status

Due to these threats, the Sevan Trout has been classified as critically endangered by the International Union for Conservation of Nature (IUCN). This means that it faces an extremely high risk of extinction in the wild, with only a small population remaining.

In fact, it is estimated that the population of Sevan Trout has declined by more than 90% in the past decade, with only a few hundred adult individuals left in the wild.

The Fight for Conservation

Thankfully, there are efforts being made to conserve the Sevan Trout and save it from extinction. The first step towards this was the declaration of Lake Sevan and its tributaries as a National Park in 1978 by the Armenian government.

Since then, various conservation organizations and government agencies have been actively working to restore the Sevan Trout's habitat and population. This includes implementing stricter fishing regulations, restoring water quality, and protecting breeding grounds.

The Sevan Trout also has a dedicated conservation program, the Sevan Trout Conservation Foundation, which focuses on raising awareness about the species and promoting responsible fishing practices.

Breeding and Nesting

The Sevan Trout's breeding season occurs in the fall, with the male fish developing prominent red and orange coloration on their sides. During this time, the males fiercely compete for females and establish territories to attract them.

Once the female has laid her eggs, the male guards the nest and fertilizes the eggs until they hatch. The fertilized eggs are then left to develop and hatch on their own, without any parental care.

The Sevan Trout prefers nesting in gravel beds in rivers, where the water is clean and well-oxygenated. This is why maintaining the water quality in Lake Sevan and its tributaries is crucial for their reproduction and survival.

A Long Life Span

One interesting fact about the Sevan Trout is its long life span. On average, they can live up to 15 years in the wild, provided the environmental conditions are suitable.

This long life span is another reason why conserving the Sevan Trout is important, as it takes several years for them to reach reproductive age and contribute to the population.

Habitat Destruction

Apart from water pollution and overfishing, the Sevan Trout's habitat is also threatened by other human activities, such as hydropower development. With the increasing demand for energy, there are plans to build more hydropower plants in Lake Sevan and its tributaries, which could have a devastating impact on the already fragile Sevan Trout population.

A Race Against Time

The declining population of Sevan Trout is a cause of great concern, not just for Armenia but for the entire world. As a unique and endemic species, they play an important role in maintaining the balance of their ecosystem.

If we do not take immediate action to protect and conserve the Sevan Trout, this mesmerizing fish could disappear forever, leaving a void in its habitat and culture.


The Sevan Trout is a symbol of Armenia's natural and cultural heritage, and its rapid decline is a reminder of the urgent need for conservation efforts. As we celebrate the unique features and behaviors of this fascinating species, we must also acknowledge the grave threats it faces and do everything in our power to protect and preserve it for future generations.

It is up to us to ensure that the Sevan Trout does not become a rare and distant memory, but rather a thriving species that continues to thrive in its home in Lake Sevan. Let us join hands and work towards securing a future for this critically endangered fish, and in turn, protect the delicate balance of our planet's ecosystems.
