Now during January several catches of Grundsjöröding are reported, but mainly in small sizes which in itself is a sign of health. Catches of char around one or a couple of hectares indicate that there is natural reproduction in the Grundsjömagasinet, says Helge Jonsson, who is chairman of the project board. The fact that it is mostly small fish that are active is due, among other things, to the fact that their fat reserves are limited and that hunger increases for that reason.
In last year's reduction fishing for whitefish, the total catch was net 3 640 safe with an average weight around 600 gram. The fish are slightly larger than in previous catches. The whitefish is in very good condition with a slightly increasing k-factor, that is, the weight/length ratio. No parasites noted.
The landing of the whitefish and transport to the container has meant significant and heavy additional work due to the low water level and the grounding at the landing site.
Bycatch of other fish is still around 3 percent of which char a significantly smaller part.
A first report of the feasibility study on
The development work within the Grundsjö project has recently been characterized by the idea of creating areas in the regulating reservoir where the lake bed and playgrounds are not laid dry during the winter. The sub-project has been named Damm i Dammen. summer 2021 measurements and studies were carried out to clarify conditions, above all regarding light penetration and conditions for nutrient production. summer 2022 a preliminary report was submitted on the appropriate location of a Dam in Dammen and the conclusions of measurements and investigations will be reported by Umeå University. The project board has made a decision in principle that a pilot plant should be built in the north-eastern part of the warehouse, in Långtjärn, which is integrated into the magazine. The conditions for food production there are good and may be on par with conditions that prevailed before the regulation. At the same time, the effect is achieved that the area is not laid dry for any part of the year.
