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.

2007-06-27

From 2007-06-26 at 13:00 the equipment is registering passing salmons.

 

2007-06-19

Because of the special environment conditions at the site in Muonio River we have to adapt the equipment to the conditions at this site. And we are now working together with the manufacturer to solve the problem.

 

2007-06-13

The monitoring is started, the beam covers 60% of the river.

 

2007-06-05

One transducer is installed at the Swedish side of the river, but not on the exact position. The transducer at the Finish side of the river tilted because of the fast stream and high water level.

 

2007-06-04:

Installation of power cable is done.

 

2007-05-20 to 2007-06-01 High water level makes the work with the installation of any equipment in the river impossible. Service of the equipment has been done during this time.
