Impossible game camera photo

I set this camera up for otter on the river and with salmon running thick I knew it was a great location. I didn't want to miss a picture so I used a fast camera with a large media card. I forgot to check the 9 volt battery that powers the board before leaving and the power dropped below what was needed to run the board, when this happens the camera will take rapid photos till the card is full. I ended up with lots of photos without anything on them and was almost ready to delete the entire card when I saw this salmon in one of the pictures.
