We propose three calibration scenarios of to date contemporary divergence of Anoplopomatidae (skilfish Erilepis zonifer and sablefish Anoplopoma fimbria) for a data set of two mtDNA loci (СOI and Control Region). The first scenario is based upon a fossil record and the second and third ones upon major palaeogeological events 3.5 and 15 Mya. Estimated evolution speeds indicate that COI evolves faster in the skilfish mitochondrial genome. There is also evidence of skilfish going through a bottleneck event limiting its genetic diversity in the relatively recent past near Japan. Sablefish had two refugia on both sides of the Pacific Ocean. The contemporary haplotype divergence was formed ~450 thousand years ago during an ice age in the Pleistocene and contemporary populations display no apparent geographic differentiation.
Two specimens of Chromis notata (Pomacentridae) and one specimen of Sagamia geneionema (Gobiidae) were captured in Suttsu Bay, the Sea of Japan. These constitute the first records of the species from Hokkaido Island, northern Japan.
