Silurus glanis
The European catfish (Silurus glanis) is one of the largest freshwater fish species, top predator and an iconic trophy-fish for recreational fishermen. S. glanis is also a highly valued species for its high quality boneless flesh and has a long tradition of aquaculture in Eastern and Central Europe. The interest of rearing European catfish continues to grow and the aquaculture production of this species has almost doubled during the last decade. However, despite its high ecological, cultural and economical importance the available genomic resources for S. glanis are very limited. To fulfill this gap we generated de novo assembly of the whole genome sequence of a female European catfish. The linked-read based technology with 10X Genomics Chromium chemistry and Supernova assembler produced a highly continuous draft genome of S. glanis: ca 0.8Gb assembly (scaffold N50 = 3.1Mb; the longest individual scaffold 13.7Mb; BUSCO completeness of 85.5%), which included 268.7 Mb of putative repeated sequences. The highly continuous genome assembly will be an invaluable resource for aquaculture genomics, genetics, conservation, and breeding research of the European catfish.
