The genetics company AquaGen has announced that it has managed to map the entire DNA sequence encoding the genes of the lumpfish (genome).
This will make it possible to study all genes that contribute to properties like growth, disease resistance and sea lice appetite with much greater accuracy than before, said it.
Sequencing of the lumpfish genome can have advantages for both industry and research institutes for different research purposes, says senior scientist at AquaGen, Tim Martin Knutsen. He has worked with the gene sequence in close collaboration with Tina Graceline and Matthew Kent from the Norwegian Center for Integrative Genetics, or CIGENE (NMBU).
The genome is open for free use and can be downloaded via figshare publication
“Tool (DOI: 1
0.6084 / m9.figshare.7301546).”
“An important milestone in the breeding program and egg production is that the genes of genital mutilation seem to have been found. It can help us look at gender differences in plant and lice, something we know very little about today.”
” We can also choose female fish for early breeding and reduce the use of male fish that do not contribute positively to breeding programs or egg production, “says senior scientist at AquaGen, Maren Mommens.
The rearing will be raised at Namdal Rensefisk, which, in collaboration with AquaGen, is now completing a state-of-the-art 80 million lumpfish fish farm in Fla tanger, Norway.
AquaGen has also developed a search engine that consists of 70,000 gene markers that are used to detect differences in DNA encoding important properties. This marker set has a high resolution and is the first designed for lumpfish.
The genome sequence and the information on where the different genes are placed in the genome allows the AquaGen to look for important genes with high precision, Knutsen said.
In winter 2018, researchers will launch a challenge test with bacterial diseases atypical furunkulos and vibrios, where they will investigate whether there are genetic differences between individual lumpfish in the resistance to these diseases.
“We have also studied lumpfish that is held together with salmon in AquaGen’s own seawater plants. We count how many lice each lumpfish has eaten while taking a tissue sample for DNA analysis. This way we can find out if lumpfish with high Lice appetite has special genetic variants we can grow for, says Mommens.
