. During the summer of 1986 a fyke‐netting programme in Lough Leane, Killarney, County Kerry, for tench, Tinca tinca (L.), yielded 142 tench of which 107 were retained for analysis. Age, growth, feeding and fecundity studies were carried out on these fish. The trophic status of Ross Bay in Lough Leane, which is known to have been eutrophic since 1971, is thought to be responsible for the improved growth of the tench when compared with two other Irish lakes, Coosan Lough, County Westmeath and College Lake, County Cork. The meristic data recorded for Lough Leane tench show variations from those listed by Lelek (1987) for tench from other European waters. These variations may be related to the low water temperatures which curtail tench spawning in Ireland, particularly in Lough Leane.
