Abstract
Several aspects of the population biology of perch (Perca fluviatilis L.) and pike (Esox lucius L.) have been studied in various lakes in the Palaearctic area. Thus, in England, the perch and pike of Windermere have been extensively studied by Le Cren (1947, 1951, 1958) and Frost (1954, 1959, 1967) respectively. The perch and pike populations in Loch Lomond, however, the largest freshwater lake in Great Britain, have so far been rather neglected. The brief publication of Hartley (1947) on the growth of perch, based on only a small number of fish, and the work of Copland (1956) on the food and parasites of pike in Loch Lomond have been the only two studies carried out so far.In 1966, it was decided to embark on a study of the population dynamics of perch and pike in Loch Lomond and the neighbouring Dubh Lochan. This project had as its principal aims (i) the estimation of the populations of various fish species in the Dubh Lochan (perch, pike and eels), (ii) the annual gross production of these fish there and (iii) a comparison of the populations of perch and pike with those in Loch Lomond with respect to age, growth, food and fecundity.
