Correction: Environmental DNA as a 'Snapshot' of Fish Distribution: A Case Study of Japanese Jack Mackerel in Maizuru Bay, Sea of Japan.

The images for Figs 2 and 3 are incorrectly switched. The image that appears as Fig 2 should be Fig 3, and the image that appears as Fig 3 should be Fig 2. The figure captions appear in the correct order.

Fig 2

Spatial approximation of jack mackerel eDNA concentration.

Based on CytB gene copy number in a 2 μL template DNA solution at the 47 sampling station, spatial variation of jack mackerel eDNA in west Maizuru Bay was estimated by approximation. The level of the approximate eDNA concentration is indicated by colors between red (relatively high concentration) and blue (low concentration). White areas suggest that the concentration approximated using a regularized spline is ≤ 0. Spatial approximation was performed using a regularized spline with a tension parameter of 40.

Fig 3

Observed fish biomass using echo sounder.

Vertical bar on the cruise track (gray line) indicates local sa values (i.e., fish biomass observed using quantitative echo sounder), which is the integrated sv of a water column with a cross-sectional area of 1 m2. This figure is depicted according to sa extracted every 80-m intervals. Note that this figure shows a summary of field observation using echo sounder. We used sv values rather than sa values as index of fish biomass in regression analyses (see S1 Fig).
