Environmental DNA (eDNA) from juvenile jack mackerel Trachurus japonicus was detected in tanks with 1, 3, 10, or 30 individuals per tank. Quantitative PCR using a set of species‐specific primers and a probe revealed that the concentration of eDNA increased almost linearly with the density of fish. The coefficient of determination ( R 2 ) in the linear regression was lower than values previously reported for freshwater fishes in similar settings.
