Sardine, but not sardine

It is a protected natural area located in northeastern Ecuador, in the Amazonian provinces of Pastaza and Orellana. The scientific name of the animal is Hemigrammus unilineatus. A species of fish in the family characidae. It is commonly called sardine, although these belong to the clupeid family. It is actually distinct from the species found. Characidae is a family of subtropical and tropical freshwater fishes.

Characidae are found in tropical lakes. Also in many rivers in South America, Central America, and central Africa. They diversified during the Cretaceous, 145 million years ago. Few snails became very large. They are important as food and today as sport. Many are very small and popular in aquariums: they are brightly colored and tolerant of living in tanks.

This species reappears after 30 years.

Long absence

The sardine that reappeared in Ecuador is a gregarious and non-aggressive fish. It reproduces easily in captivity. The National Institute of Biodiversity of Ecuador announced the discovery. INABIO, for its acronym in Spanish, is attached to the Ministry of Environment. The rediscovery was documented by several ichthyologists.

In the world the species was first described 163 years ago in Trinidad and Tobago. In Ecuador the species was first reported in 1981. As of 1991, no study has been able to report the presence of this species in Ecuador. The species is difficult to find during ichthyological surveys.

They inhabit slow moving rivers, tributaries, sinuous lakes and ditches. It is a peaceful species that coexists easily with other species. And, despite its long absence in Ecuador, it never completely left.
