Here are some smolts that were caught on the fish pass camera at TWP. It is unclear at the moment whether they are sea trout or salmon smolts. The v-shaped tail may not necessarily indicate salmon at this stage of development.
The fish near the camera look huge but you can see from the fish in the background and especially in the bottom photograph that they are indeed smolt-sized. The red strip is 600mm wide. Although good for species identification purposes, it is very difficult to assess the size of fish from a side view like this and it is hoped that in time an overhead camera may be fitted to make the task easier.
