Laxräknare – Muonioälven

Lohenlaskenta – Muonioväylässä

 

We can now see salmon passing the echo sounder beam. The beam coverage has been  about 50% of the water column until 2007-07-13. 

 

Because of the poor coverage percentage we don’t present any number of salmon passing down stream this year.

 

From 2007-07-13 a second transducer is installed and new settings for the old transducer gives more accurate data and now we estimate that the beam coverage is 80% of the river cross section, together with the leading fences.

 

From 2007-07-30 the second transducer was uninstalled. The beam coverage is from this point 50% of the water column.

 

The monitoring will be ended at Muonioriver 2007-08-27.

Fishermen changed setting for the transducer on the east side of the river at 03:00. Poor coverage until 2007-07-23 at 08.00.
