An angler from Tallaght hopes to net some fellow enthusiasts for a fish stock conservation project.

The local fisherman, Shane O’Reilly, is helping spread the word about the National Salmon Scale Project among other anglers in the area.

Shane was joined at the launch of the new initiative by Minister Sean Canney, as they urged locals to become citizen scientists for this unique project.

“As we celebrate International Year of the Salmon, this project will help researchers understand the challenges which salmon are facing today,” Minister Canney said.

“The project, which has been initiated by Inland Fisheries Ireland aims to collect vital information through scales taken from salmon and sea trout which are caught in Irish rivers and lakes and will contribute to international efforts to conserve wild salmon”.

Fish scales record the life history of a salmon and one scale can reveal a lot about the lifestyle and behaviour of the fish.

Scales can tell scientists what age the fish is, how many winters it spent at sea, how many times it spawned, how slow or fast it grew, what it ate and how long it spent in the river before it went out to sea.

Scales can also reveal the general feeding area where the salmon travelled to in the ocean, whether it went to the Faroe Islands, the Norwegian Sea or all the way to West Greenland.

Scales help scientists to understand the biology and ecology of Irish salmon and sea trout.

As part of the project, anglers in Dublin are asked to take a scale sample from a salmon or sea trout by gently scraping and removing approximately 20 fish scales using a clean knife.

Anglers are then requested to post their samples to Inland Fisheries Ireland using the sample envelopes which will be made available to them.

Scales can be removed from both harvested and catch and release fish.

Sampling of fish for release should be handled carefully and fish should be only briefly removed from the water with every effort made to avoid injury or stress while weight should be estimated.

Information from salmon scales is used in setting conservation limits for Irish rivers.

Conservation limits for each river are set based on the proportion of salmon who have spent one winter at sea and those that have spent multiple winters at sea.

The ‘conservation limit’ for a river represents the number of spawning salmon required to produce the next generation of salmon and this information helps inform angling regulations and management.

All scales collected through the National Salmon Scale Project will be added to the National Salmon Scale Archive which is managed by Inland Fisheries Ireland.

The National Salmon Scale Project aims to increase the scale resource available to scientists for ongoing and future research.
