6am Saturday and again I am on the bridge. Over night our search continued and we have trawlers on the radar again. The green smudges with twin trails are the telltale signs we look for on the radar. Usually the radar is the first sign and then lights or silhouettes appear on the horizon as we get closer. But the fog that rolled in yesterday has stuck with us and from the bridge it's only possible to see about 50 metres in to the distance.

Other than that the weather conditions are perfect. The rolling swell from the other day has stopped and the wind is calm. Both things mean the fog is probably here to stay.

Throughout the night the mate and watchkeeper have tracked the position of the trawlers. When I arrive on the bridge in early morning there is a tangle of information in the note book. We note hourly positions of the trawlers and when we see the two smudges on the radar merge and change speed we know that they are hauling and refitting their net.

All of this is noted down and we are building an extensive picture of the fishing effort in this area.

A few days ago we found the mutilated bodies of three dolphins - fishermen trying to hide the evidence at sea. Today it seems the weather is colluding against us to hide the evidence too. The morning hauls are all done over the next couple of hours. I can't help but wonder how many bodies will drift away in the morning fog never to be seen again.
