Three new species of tiger fish were discovered

The report, published in the journal Genome Research, said US scientists have discovered three new strains of amphibian fish using mitochondrial DNA sequencing technology.

This proves that in global ocean, there is not only one type of tiger fish.

In the study, scientists carried out the determination of the mitochondrial DNA sequence of 139 tuna fish taken from the North Atlantic, North Pacific and marine areas near the Antarctic continent by using ' Highly parallel sequencing technology. '

The study found three new species of tiger fish, of which two new strains live in the Antarctic sea, the main food is fish and seals. And the remaining new strain lives in the North Pacific.

Genetic expert Philip Moline of the US National and Atmospheric Administration, in charge of the research team, said that, like other tiger fish, the mitochondria in the tiger fish body are difficult to transform. time, so it is very difficult to detect new strains without observing their entire genome.

However, 'parallel sequencing technology' can complete sequencing of the tiger fish mitochondrial genome by measuring tiger fish samples around the world, thereby distinguishing Get a new strain. /.
