For a few minutes the fjord looks like milk. For a few minutes the inner fjord looks like milk. Our new in situ optics allow for a direct insight into the spawning beds. In many of the transparent eggs the yolk can be seen, with the tail grown around. Best visible are the black eyes.
Some eggs are empty already, and above the middle a hatched larvae swims along.
In the three weeks since spawning green algae have also grown on the substrate. At the right side of the image a herring is struggling to get out of these greenalgae. In the upper egg the long tail winds around the yolksack. The two big black eyes and the brain are visible. A second optic sensor magnifies the area behind the brain.
