The warmth in the country, and especially in northern Sweden, has caused the water temperatures to rise. This can create problems for fish that are sensitive to the high temperatures.
Fishing conservation areas in Jämtland are therefore recommended to close the fishing when the water passes 18–20 degrees. This mainly applies to flowing water as the fish can rarely seek deeper and cooler water.
Extra stress
Species that are sensitive are mainly char, trout and grayling.
Catching and then releasing a fish means extra stress for the fish now that it is so warm in many waters. Even if it swims away when you release it, it is not certain that it actually survives, says Anders Rydeborg, fish biologist at the county administrative board, to SVT Jämtland.
The fishing was closed last week at several fishing conservation areas in the county, reports P4 Jämtland.
In the country, there are approximately 2,000 fishing conservation areas and usually consist of parts of a lake or a watercourse. The areas are managed by an association that consists of fishing rights holders. It is the fishing conservation areas themselves that decide whether the fishing should be closed.
”A bit exceptional”
The county administrative board in Västerbotten states to TT that a recommendation is not current as the fishing conservation areas often regulate this on their own.
Martin Rydgren, investigator at the unit for fish regulation at the Marine and Water Authority, thinks that the county administrative board in Jämtland is doing the right thing but that the responsibility lies with the fishing conservation areas.
It is more of a precautionary measure. It is quite normal that you close the fishing when the water is warm. Now it has been very warm for a while, so it is a bit exceptional, he says to TT.
