IS IT NECESSARY TO COUNT SALMON REDDS?
The Silver Taiga Foundation has published the booklet about the monitoring system of the salmon fish species spawning.
In 2011 the Foundation together with the partners initiated the monitoring of the Atlantic salmon spawning quality under Model River Mezen project aiming at defining the changes in the number of spawning fish on Mezen River tributaries with the total length more than 200 km. The received monitoring data can be used further in the implementation of the measures of the population conservation and restoration. The given method does not give a good quantification of the local population but it allows to register the spawning activity in the head of Mezen River.
The method has the following advantages: it is not difficult to realize the method, it is not necessary to complete the authorization documents and there are no special requirements to the expedition equipment. In the other regions the monitoring system of the salmon fish species spawning is conducted in the other way – they use sonar sets to register the migratory species, flying machines or they catch the fish.
Due to the interest of the non-governmental environmental organizations and sectoral science to the used spawning records methods, the Foundation together with Karelian scientific center of the Russian Academy of Sciences have tried to combine the gained experience and to present it to all interested parties for practical application.
The Foundation thank everyone who took part in the booklet elaboration.
The booklet is available in the Russian language.
