Catches of eel from the Shannon lake system of 35,000 ha have fluctuated from 10 to 46 t per annum over the period 1964 to 1988. Peak catches are observed at intervals from 3 to 5 years. Catches increased following improvement of fishing gear but otherwise remained steady in spite of a sustained increase in stocks. Migration was observed every month except June. The numbers of female eels>60cm decreased over the period. Male eels ranged from 39 to 44 cm, ages 5 to 15; females from 45 to 99 cm, ages 8 to 30 years.
