Brown trout Jõeforell or hõrnas Salmo trutta morpha fario
Salmon, sea trout and brown trout have their pressing spawning period. We can observe the spawning of brown trout by direct stream already for the third year in the brook on the grounds of the Põlula fish raising enterprise of RMK. By tributaries the brook is connected to the Kunda river.
Brown trout arrived already in ancient times to rivers connected to the sea and in all the rivers and brooks where trout go to spawn in autumn, brown trout are also always present. In flowing waters that have never been connected to the sea the fish have been established by humans already since centuries.
Compared to last year more different individuals of trout are visible at the somewhat adjusted spawning ground and there is also a greater number of larger sized fish. It seems that the spawning proceeds nicely in the waters here, the females build nests lying on their side and flipping their tails. There is sufficient water too in the brook.
Nest robbers and fanciers of the delicate fish flesh have not appeared at the spawning ground yet this year. By following the camera stream we will see how the robbers will act now, but it is to be feared that one or the other of them will find their way here – of course an intriguing wait too.
At the spawning period last year a great surprise and previously not known fact was revealed – that mallards can be nest looters and trout roe gobblers. When darkness fell mallard groups could be seen trampling at the spawning spots and getting out the roe from under the gravel, then eating the floating roe grains. Who would have believed that mallards could be such rascals?
Should you happen to hear occasional short cheeps against the backdrop of rather monotonously purling water then imagine that at the brook there are shrub-sized alders where a kingfisher comes to sit. Now it cheeped again.
