From: Fusion of piggyBac-like transposons and herpesviruses occurs frequently in teleosts
Teratorn-like viruses exist in multiple copies in host genomes Estimated copy number of Teratorn-like viruses in the genomes of some teleost fishes. Copy number was estimated by mapping of Illumina short read data against reference genome data, calculating the coverage at each nucleotide position, and then dividing the average coverage value of herpesvirus core genes by the average coverage of the coding region of host genes
