As scientist Metvei Tyaptirgyanov, “gold crucian” has been in lakes and basins of Yakutia for a long time. Though, it was has been found in Upper Bylyy for the first time. This species of cyprinoid fishes receives such interesting color in “mating season” to attract females.

“Matvei Lompordurov told me, that the crucian is weighs 200 grams and its length is 23 cm. I asked him to hold the crucian in the barrel of 200 litres of water this night, and let it go by scoop-net in next lake in the morning. These days I plan to go to this village and study the “gold crucian”, Doctor of Biological Sciences, the NEFU teacher Matvei Tyaptirgyanov told YSIA correspondent in the telephone conversation.

According to Matvei Matveevich, “crucian carp” was called “Yakut crucian” earlier, and it has lived in the Yakut lakes. One may also find “silver crucian” in the republic basins, but, a strange fact, much rarer.

“Crucian takes the gold color in estrus from June to August. But due to the climate warmingin Yakutia, this sort of crucian carp continued estrus in September too – blood corpuscles activate in this season and it causes bright, significant for eyes color. Unfortunately, the third period larval fish of gold fish estrus is doomed to die because of the coming cold”, Tyaptirgyanov said.

The scientist promised YSIA correspondent to tell the results of the study of gold crucian right after research.

Note:

First to give the detailed description of crucian from the Yakut basins was famous ichthyologist Fedor Kirillov during the expeditional research in the middle stream of the Lena River in 1948-1951. On the results of research Kirillov concluded, that crucian, inhabiting Central Yakutia lakes, belongs to the crucian carp species, unknown before. So the crucian from our basins received its “birth certificate” and official name – the Yakut crucian Carassius carassius jacuticus Kirillov. Tall body, dark-brown back, gold sides, fat lips and thoughtful sight make this “gold crucian” alike imposing and respectful State Counsillor.
