European Eel

May 23, 2017 alice Leave a comment

European eels, like salmon, are migratory fish. Eels were one abundant in the rivers of the Maigue catchment but are less so today. The Civil Survey of the mid 17th century mentions the presence of up to 8 eel weirs on the Camogue between the Maigue confluence and Dunkip. Young eels grow to adults in rivers and lakes and then migrate to spawn in the Sargasso sea off the east coast of the U.S., a distance of over 5,000 km. The European eel is classified as critically endangered in Ireland and other European counties, and is the most threatened native fish..

Lampreys are primitive eel-like fish. Two species are found in the Maigue catchment: brook lamprey and river lamprey. Sea lamprey, which spawns in the lower Shannon and Mulkear river, have not been recorded from the Maigue system.

Northern pike, a large predatory fish, are found in the lakes of the catchment (L. Gur, Dromore Lough, Bleach Lough and L. Nagirra, and there are reports of them occurring in the slower reaches of the R. Camogue. The 17th century Civil Survey refers to a weir at Mainistir where eels and pike were trapped.

These are small fish that are common in the Maigue catchment. Collectively they may be known as (pinkeens”). Minnows and stoneloach are introduced species. Minnows and sticklebacks often form small shoals. They are frequent prey of larger fish such as trout and perch...

Dace

May 23, 2017 alice Leave a comment

Dace are a non-native and invasive species first recorded in the R. Maigue near Adare Manor by electro-fishing in 2004. Dace are also found in the Lower Shannon and Mulkear. They were not recorded in a survey of the catchment upstream of Adare in 2013. This suggests that dace have not spread to other parts of the Maigue catchment, but further surveys are needed to confirm..

Crayfish

Cray are not fish, but freshwater crustaceans related to lobsters. White–clawed crayfish (Austropotamobius pallipes), Ireland’s only native crayfish, are widely distributed in the main channel of the Maigue and in the larger tributaries. Crayfish are an important food item for fish, especially trout and eels. White-clawed crayfish are protected in Ireland under the Wildlife..

It is often seen sitting on a rock in the river bobbing or ‘dipping’ its head up and down. Dippers build a large dome-shaped nest out of moss, on sheltered areas of the riverbanks. They often build their nests under..
