Trout without fat fins can be caught if it is at least 60 centimeters long. Fatfin trout has been financed.

The size of fin cut, i.e. stocked trout, has been increased in the Kymijoki watershed.

In the future, in Päijänte, in both Heinola and Hartola fishing areas, you can catch trout without fat fins, which are at least sixty centimeters long.

The purpose is to improve the yield of the plantations, as larger fish survive better in the wild and their chance to reproduce naturally increases. For example, the fish planted in Päijänte grow quickly because the most important food, muikku, is abundant. Due to the rapid growth, some of the placentas are caught too early, and they may not have had time to grow to sexual maturity.

The new, higher minimum size than the one recorded in the Fisheries Act has been approved in the use and management plans of fisheries areas.

The variegated fan worm has been found in four places in the Åland archipelago. Ballast water has been suggested as the primary cause of the spread.

A new alien species, the rainbow fan worm, has established itself in Åland. It has been found in four places in the Åland archipelago.

The variegated fan worm is an alien species that was found in the Baltic Sea for the first time in 2012 in Pärnu bay. The first observation from Finnish coastal areas is from 2014 and from Åland from 2021.

The origin of the centimeter-long roundworm is still unknown, but ballast water has been suggested as the primary cause of its spread.

Also observed mud tubeworms and mud mussels

In other respects, the benthic fauna survey states that mud pipe worms are now the most widespread group of benthic animals in Åland. Slime tubeworms were found in Åland for the first time in 1993. Since then, they have spread all over Åland’s coastal waters.

The collapsed nest was found when WWF and volunteers were cramming helpers for nesting. Nesting peace will be declared next week.

The nest of the Saimaa norpa has been blatantly disturbed in southern Saimaa.

On a snowmobile, I had been driven crosswise over a snowbank, where a norpa had already tried to make a nest. The nest had finally collapsed and there was only an opening made by a norpa.

WWF experts and volunteers found the destroyed nest when they were digging up helpers to facilitate nesting.

WWF will declare a nesting ban for Saimaa grouse next week, but those moving around Saimaa should already remember to respect the Saimaa grouse’s nesting nests.

More than 80 percent are of the opinion that there are too many wolves in Kuhmo. The majority of respondents considered the number of bears, lynxes and wolverines to be appropriate.

There are too many wolves, not so much other big beasts. This is the opinion of the majority of respondents to the Kuhmo large predator working group’s municipal survey.

About 950 responses were received to the municipal survey conducted between December and January. Two thirds of them declared that they were from Kuhmo.

More than seven out of ten feel that large beasts have been harmful to everyday life. The majority of them are of the opinion that large animals prevent the hobby. Every fourth of them experiences fear and more than four out of five say that the number of large carnivores has influenced their keeping dogs or hunting with them.

The majority would increase population maintenance hunting

More than half of the respondents would increase population management hunting of large carnivores. About a quarter would increase so-called removal permits in order to reduce the number of prey. Few people think that people should just learn to adapt to life with beasts.

The ice crust in the Hange makes it difficult, for example, for owls to prey on owls and grouse birds to protect themselves in severe frost.

For many birds living in the forest, the search for food and protection is difficult in some places due to the ice crust on the surface of the snow cover or in the middle.

January was exceptionally mild in many places, and the frosts that came after the rains made the surface of the snow harden.

It is difficult for owls that use moles or smolts as food if they cannot catch prey through the ice cover.

According to Kärkkäinen, however, so far no signs of several starving birds have been observed. The weather in the coming weeks will determine how the owls will fare in those areas where there is ice cover.

According to Metsähallitus, the cubs seem vigorous, even though the winter has been relatively mild even in the north.

The mink litter observed in Finland after a long break seems to be surviving well. All three puppies have been seen during the winter on the fells eating dog treats from the feeding machines, says Metsähallitus.

According to it, the puppies have appeared to be vigorous.

Even in the north, the winter has been relatively mild, which usually makes life difficult for the foxes, because their natural food, i.e. the cocoons, can suffer from the warm winter.

However, it hasn’t rained on the fells this winter, so there haven’t been any problems for the skiers. The success of the nymphs also directly affects the survival of the nael.

Money is still the measure of efficiency and the best way to get one’s agenda through, at least in the corporate world, writes Thurén.

I got to know a graduate engineer who works in a large international company. He said that he is most motivated in working life by situations in which he manages to save the energy of large machines or reduce emissions through various actions.

If, for example, a large process industry factory can be made to operate in such a way that it does the same work but saves even 1% of energy, the savings when scaled up are enormous. Saving is often saving both in terms of emissions and money.

The Master of Science in Engineering is also the mother of a small child, and she is interested above all in what kind of planet we leave to our children.

We started to think about whether decisions could be justified or tried to be carried through by talking directly about the environmental aspect, such as emissions, biodiversity or the climate crisis. We came to the conclusion that no. Money is still the measure of efficiency and the best way to get one’s agenda through, at least in the corporate world.
