#INLAND WATERWAYS - Inland Fisheries Ireland (IFI) has announced the results of studies on the genetic makeup of brown trout stocks in the Suir and Boyne river catchments.

These studies form part of a wider scheme looking at Ireland's larger riverine catchments - assisted by the Office of Public Works, geneticists from UCD and trout anglers across Ireland - and involve a chemical analysis of scale samples from fish known as 'micro-satellite DNA analysis'.

The results from the Suir and Boyne are described by IFI as "quite amazing" and "of significant value" to managing the fisheries in these areas.

In both catchments, the first step saw trout stock samples of young fish examined genetically, and they were shown to be discrete - in other words, fish from any given tributary were found to be genetically different to those from others.

The next step involved samples of adult fish from the main river, contributed by anglers, which were then related to the different tributary genetic types.

Summary results from the Suir and Boyne show that there are respectively seven and five distinct families of trout in the catchment area; that most fish born in tributaries migrate to the main stem till adulthood before returning to their tributaries to spawn; that numbers migrating from individual tributaries are variable, but fish don't cross into adjacent catchment areas; and that there movement of young trout along the river system is "extraordinary", with fish often migrating from near the source to the mouth.

More details on findings for the Suir catchment and Boyne catchment are available on the IFI website.

The Irish National Sailing and Powerboat School is based on Dun Laoghaire's West Pier on Dublin Bay and in the heart of Ireland's marine leisure capital.

Whether you are looking at beginners start sailing course, a junior course or something more advanced in yacht racing, the INSS prides itself in being able to provide it as Ireland's largest sailing school.

Since its establishment in 1978, INSS says it has provided sailing and powerboat training to approximately 170,000 trainees. The school has a team of full-time instructors and they operate all year round. Lead by the father and son team of Alistair and Kenneth Rumball, the school has a great passion for the sport of sailing and boating and it enjoys nothing more than introducing it to beginners for the first time. 

Programmes include:

  • Shorebased Courses, including VHF, First Aid, Navigation
  • Powerboat Courses
  • Junior Sailing
  • Schools and College Sailing
  • Adult Dinghy and Yacht Training
  • Corporate Sailing & Events

History of the INSS

Set up by Alistair Rumball in 1978, the sailing school had very humble beginnings, with the original clubhouse situated on the first floor of what is now a charity shop on Dun Laoghaire's main street. Through the late 1970s and 1980s, the business began to establish a foothold, and Alistair's late brother Arthur set up the chandler Viking Marine during this period, which he ran until selling on to its present owners in 1999.

In 1991, the Irish National Sailing School relocated to its current premises at the foot of the West Pier. Throughout the 1990s the business continued to build on its reputation and became the training institution of choice for budding sailors. The 2000s saw the business break barriers - firstly by introducing more people to the water than any other organisation, and secondly pioneering low-cost course fees, thereby rubbishing the assertion that sailing is an expensive sport.
