#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.

About Currachs

A currach is a type of boat unique to the west coasts of Ireland and Scotland. Traditionally, currachs have a wooden frame over which animal skins or hides are stretched. These days, the wooden frame is more likely to be covered in canvas, which is then painted with tar to make it waterproof.

"Naomhóg" is the name given to the type of currach which used by coastal communities in Cork and Kerry. Currachs differ from each other from region to region. Naomhógs are slightly longer than the currachs used in the West of Ireland.
 
Some believe that currachs first came to the Dingle Peninsula in the early 19th century. They say this type of boat was introduced from Clare, where currachs are known as "canoes". 

Currachs are a unique type of boat that can be found on the west coasts of Ireland and Scotland. These boats are traditionally constructed using a wooden frame over which animal skins or hides are stretched. While this practice is still observed by some, many modern currachs now feature a canvas covering which is painted with tar to make it waterproof.

In coastal communities located in the Cork and Kerry regions, a specific type of currach is used which is known as a Naomhóg. Naomhógs are slightly longer than other types of currachs used in the West of Ireland. It is believed that currachs were first introduced to the Dingle Peninsula in the early 19th century, having been brought over from Clare where they are known as "canoes".

Despite the fact that currachs have been in use for centuries, the different regions in which they are used have developed their own unique variations. As such, currachs can differ from one another significantly depending on their geographic location. Nonetheless, these boats remain an integral part of coastal communities, serving as a reminder of our shared maritime heritage.
