Brown trout   Jõeforell or hõrnas   Salmo trutta trutta morpha fario 

Usually it is sufficient for a spawning milt fish, i e a male, to look his competitor squarely in the eye or to push it with his nose, and the smaller curious explorer disappears quickly (this we often see at the spawning ground). In the video the obstreperous individual is punished by a painful tug at the fin.

Otter    Harilik saarmas    Lutra lutra

The otter belongs to the indigenous Estonian species and is a mammal protected by law. We have to do with an extremely mobile animal whom scientists have difficulties in monitoring.

With a good hearing and sense of smell it distinguishes moving objects in water as well as on land easily. In contrast an unmoving observer at the river bank may not be noticed.

Mallard     Sinikael-part     Anas platyrhynchos

…and so they have arrived at the spawning ground – three individuals passed the camera.

In the dry summer last year the water level was some twenty centimetres lower and the mallards could successfully loot the spawning nests of the brown trout. With a higher water level it is more complicated for them and the video shows this too.

The body length of mallards is about half a meter or a little more, adults weigh a kilo or some hundred grams more.
