Dublin has yet another thing to celebrate with the news that wild Atlantic salmon have returned to what was long regarded as the dirtiest of the capital's inland waterways.
The Irish Independent reports that the fish have been spotted along the banks of the Tolka between Glasnevin and Finglas for the first time in at least 100 years.
Efforts to clean the river in recent years, as well as the removal of man-made weirs, are thought to have aided the recovery of the Tolka, which now provides plentiful nutrients for migratory fish.
Atlantic salmon in particular are considered by scientists to be a 'bio-indicator' in that they require a very high standard of water, so their presence in a given area defines it as a healthy environment.
The Tolka joins the Liffey and the Dodder in the list of Dublin rivers hosting thriving stocks of young fry in what has been a bumper year for salmon angling across the country.
The Irish Independent has more on the story HERE.
In preparation for the field trip Des Chew, Project Manager of the Dublin Angling Initiative visited the school and gave the pupils a talk on water quality, the lifecycle of trout and the art of fly-fishing. The pupils then participated in a field trip along the River Dodder, starting at Rathfarnham shopping centre and finishing at the confluence of the Dodder and Owendore rivers at Bushy Park. Minister Lenihan was joined by TV celebrity and angler Derek Davis.
Fisheries staff from Dublin Angling Initiative and Inland Fisheries Ireland took kick samples and were ably assisted by Gerry Heaslip and Brian McDonagh of the Dodder Angling Club. The children identified invertebrates and their delight could be heard far and wide as they found many different species of stonefly and caddis fly! Looking at water pollution indicators, the children could establish that the presence of these different types of invertebrates indicated the good water quality in the river. This is not surprising given the very healthy stock of wild brown trout in the river.
Minister Lenihan, remarked:
'It is wonderful today to see the young people out learning about their local river. The River Dodder is a very important river in south Dublin, it has good water quality, contains a healthy population of wild brown trout and is a wonderful angling resource.
This is in no small part due to the excellent relationship that the Dublin Angling Initiative and Inland Fisheries Ireland have with the Dodder Angling Club'.
Following this the children were given information packs on fish species, invertebrates and fish species posters. St. Pius X School has participated in Inland Fisheries Ireland's 'Something Fishy' programme in previous years and were thrilled to take part in such an exciting field trip of their local river.
The 'Something Fishy' project was developed by Inland Fisheries Ireland (formerly the Central and Regional Fisheries Boards) in association with Blackrock Education Centre and has proved a highly successful way of encouraging young people to take an interest in Irish fish species, their local environment and habitat. In 2010 almost 1,000 young people participated in the Something Fishy programme within the Eastern River Basin District.
