To review files collected by the DVMD:

• Open the relevant .csv file.

• Ensure everything is set up as required in the Settings tab.

• Scroll down through the list in the table using the arrow keys.

• Use the buttons in the video display box below the video screen to play the

clip (Figure 27).

• When a fish is seen, the species information can be selected from the drop

down menu in the video display box (species can be added in the Settings

tab).

• The direction of movement can be altered if necessary using the Direction

selection buttons below the fish information box (Figure 27).

• The fish can be sized by first highlighting the calibrate section. Hold down the

left mouse button and draw a line on the video screen between points a

known distance apart, preferably in roughly the same area as the fish. Enter

the length of the line. Then click in the Size section and draw a line along the

fish. The fish length will be displayed in the ‘length of line cm’ box.

• When all of the fish information has been input, click ‘add fish information’ in

the bottom right hand corner of the video display box (Figure 27). The

information will be added to the table.

• When the file has been reviewed, make sure it is saved before closing or all

of the changes will be lost.
