Lumpfish (Cyclopterus lumpus) genome assembly. Lumpfish (Cyclopterus lumpus) genome assembly

Over the last six years, lumpfish (Cyclopterus lumpus) have been extensively employed to control sea lice affecting Atlantic salmon. Unfortunately, lumpfish deployed in net pens suffer high mortalities (50 - 98%) in late summer, due to increased sea temperatures and higher occurrence of bacterial infections. Furthermore, Lumpfish is an opportunistic feeder and only 13.5 - 38 % of lumpfish present in net pens have been found to graze on sea lice. Robustness and sea lice grazing are therefore key traits whose improvement, through genomics-based selective breeding, would bring benefits to salmon aquaculture. We have whole genome shotgun sequenced DNA from a single male using both Illumina short-read and Oxford Nanopore long-read technologies, and constructed a de novo assembly using Masurca (scaffolds = 5735, scaffold N50 = 811K, total bases = 553 MB).
