Chromosome-Level Genome Assembly of the Butter Clam Saxidomus purpuratus.

Herein, we provide the first whole-genome sequence of the purple butter clam (Saxidomus purpuratus), an economically important bivalve shellfish. Specifically, we sequenced and de novo assembled the genome of Sa. purpuratus based on PromethION long reads and Hi-C data.

Gonadal Abnormality and Intersexuality of Oplegnathus fasciatus (Teleostei: Oplegnathidae) Collected from the Southern Coast of Korea: A Case Report.

We report on the gonadal structure abnormality and intersexuality found from a survey regarding the reproductive potential of the rock bream, , along the southern coast of Korea. In total, 448 samples were collected for histological analysis (total length 27.5±6.

Characterization of the complete mitochondrial genome of Golden cusk, (Ophidiiformes:Ophidiidae).

The complete mitochondrial genome of was determined by the bioinformatic assembly of the next generation sequencing (NGS) reads. Total length of the mitogenome was 16,717 bp, which harbors the conserved 13 protein-coding genes (PCGs), 2 ribosomal RNAs (12S and 16S), 22 tRNAs, and two non-coding region (the control region and the origin of light-strand replication). Among 13 protein-coding genes, unusual start codon (GTG) was exclusively identified in COX1, while the incomplete stop codons (TA- or T-) were detected in COX2, COX3, ND2, ND3, ND4 and CytB.

First record of three species of octopodidae and gonatidae, cephalopods in the East/Japan Sea.

Three species of the unrecorded octopus and squids, Octopus megalops, Berryteuthis magister and Gonatopsis makko were collected for the first time from the East/Japan Sea in June, 2005. New Korean names proposed for these three species are "Big-eye octopus, Mako gonate squid, Schoolmater gonate squid" for the O. megalops, B.
