A chromosome-anchored reference assembly for the gray snapper, Lutjanus griseus.

Background: The gray snapper (Lutjanus griseus) is a marine reef fish commonly found in coastal and shelf waters of the tropical and subtropical western Atlantic Ocean. In this work, a draft reference genome was developed to support population genomic studies of gray snapper needed to assist with conservation and fisheries management efforts.

Methods And Results: Hybrid assembly of PacBio and Illumina sequencing reads yielded a 1,003,098,032 bp reference across 2039 scaffolds with N50 and L50 values of 1,691,591 bp and 163 scaffolds, respectively.

Genomic resources for the Yellowfin tuna Thunnus albacares.

Background: The Yellowfin tuna (Thunnus albacares) is a large tuna exploited by major fisheries in tropical and subtropical waters of all oceans except the Mediterranean Sea. Genomic studies of population structure, adaptive variation or of the genetic basis of phenotypic traits are needed to inform fisheries management but are currently limited by the lack of a reference genome for this species. Here we report a draft genome assembly and a linkage map for use in genomic studies of T.
