This characterization could represent a qualitative leap in the aquaculture of this species, of great commercial value
Andalusia - The Ministry of Agriculture, Livestock, Fisheries and
Sustainable Development, through the Institute for Agricultural and
Fisheries Research and Training (Ifapa), has led the work that has made
it possible to organize the sole genome into 21 chromosomes. This has
been done by combining very long DNA sequences and genetic markers and
will allow it to serve as the basis for mapping markers and their
distribution throughout the genome. The integration of the physical and
genetic map opens up new possibilities for the aquaculture exploitation
of sole, a species of high economic interest in Europe.
This genomic resource is of great interest for sole aquaculture, since
it offers detailed information to study the genes that determine the
traits of great commercial interest, such as growth rate. In addition,
according to a statement, tools for chromosome mapping and kinship
assignment, which are essential for genetic selection programs, have
been validated.
The results of this
work, which has been carried out in collaboration with several national
institutions such as the National Center for Genomic Analysis
(CNAG-CRG), the National Institute of Toxicology and Forensic Sciences
(INT), the University of Malaga and the University of Las Palmas de Gran
Canaria, have been published in the prestigious Scientific Reports
magazine.
Ifapa has been developing work and research in the field of sole aquaculture for 20 years with a view to optimizing its production, both in technological developments and strategies for disease prevention, improvement of its diet and growth and quality parameters. Furthermore, the genetic studies carried out so far have made it possible to collaborate closely with the industry to optimize their production and select the ideal animals for their recirculation culture.
Andalucian Sole Production
The annual production of sole in Andalusia exceeds 530,000 kilograms of fish in the fattening phase, which, based on its value, is close to six million euros.
In this aquaculture field, the province of Cádiz stands out, which concentrates practically the entire production (almost 534,000 kilograms valued at 5.9 million euros). The rest of the records correspond to companies in the province of Huelva, which produce 146 kilograms of sole which, economically, is close to 2,500 euros.
