Spatiotemporal distribution of two mackerel species, <i>Scomber japonicus</i> and <i>Scomber australasicus</i>, in the Bungo Channel, western Japan

Abstract

To reveal the distribution patterns of mackerel in the Bungo Channel, western Japan, we investigated catch statistics and specimens of chub mackerel Scomber japonicus and spotted mackerel Scomber australasicus sampled atˆsh markets from 2007 to 2017. Chub mackerel were caught mainly in the northern part of the Bungo Channel

Development of species‐specific multiplex real‐time PCR assays for tracing the small pelagic fishes of North Pacific with environmental DNA

“…However, since the two species are difficult to be distinguished at early life stages and catch data is always combined by the two species, the detailed difference in their ontogenetic migration is still undetermined. Limited studies showed warmer preference of blue mackerel than chub mackerel both for larval (Sassa & Tsukamoto, 2010) and adult stages (Goto et al, 2020). The mackerel catch along the Iwate coast has two peaks in spring and winter (Figure S4).…”
