According to the Regional Administrative Agency, the production of fry near the shore could have caused water pollution.
Last year, the laboratory-raised wrasse fry were returned to their home river, and they survived the winter. If the chicks survive to adulthood, the researchers have plenty of time to restore natural reproduction.
Microscopically small river pearl mussel chicks find a temporary home in the middle of the gravel and stones at the bottom of the plastic box.
A year ago, raw chicks grown in laboratory conditions were brought to Luttojoki. Luttojoki raakku is a very endangered species, and now their young have survived their first year of life in their home river.
Before the raccoon chicks get to live in natural waters, their growth and life are monitored in plastic boxes.
– From now on, the chicks’ growth will be monitored for a few years. The hope is that growth will take place, and in a few years the chicks will be released here at the bottom of the river, says Salonen.
Luttojoki raccoons have not been able to reproduce naturally for decades, even though the species has been protected for almost 70 years.
In the fall of 2020, larvae of clocids were collected from Luttojoe to be grown for the Konnevesi research institute. Raakku needs salmon to reproduce, which have not come up to the Luttojoki for decades after Russia dammed the Luttojoki.

Great trivia quiz – test your knowledge about pollinators! Read More »
Pollinating insects need water and pollen for food. When you grow pollinator-friendly flowers in your yard, you also ensure a bountiful harvest of fruit trees and berry bushes.
The most important thing when planning balcony or yard plantings is to choose flowers so that there is enough food for the fluffy ones from early spring until autumn. This way, people also have enough eye candy for the whole summer.
Although most flowers attract pollinators, not all flowers are created equal. Highly cultivated flowers with many layers of petals may not produce any nectar at all.
In plantings, it is good to prefer simple flowers, preferably those that can also be found naturally in Finland. Such flowers are much better able to withstand the changing summer heat and are therefore easy to take care of.
At the nursery, you have to be careful that no pesticides have been used to grow the seedlings, because they are also dangerous for pollinators. If possible, prefer seedlings grown in your home country.
