A decade of studies at Loch Fleet, Galloway (Scotland): A catchment liming project and restoration of a brown trout fishery

Loch Fleet is a small upland lake in the hills of Galloway in southwest Scotland. In the 1970s the waters of the loch became more acidic and a brown trout fishery failed. This account summarises an experimental project, the "Loch Fleet Project" initiated in 1984, designed to reverse acidification of the loch by liming parts of the catchment. Liming about 40% of the catchment in 1986 and 1987 raised the pH and calcium levels, and reduced toxic aluminium concentrations. The improved conditions had been maintained up to 1994, but water in the loch, and its principal inflow stream, is now falling close to the desired threshold of quality. After liming, restocking with local strains of trout in 1987 was successful, and a self-recruiting population became established within 2 years. Recruitment is highly variable, however, and was attributed to severe spring conditions and the limited spawning capacity of the nursery stream, rather than to water quality

Household Size Economies: Malaysian Evidence

People live in households with different size and composition and they consume a variety of goods; categorised as private and public goods. With the existence of public goods in the household, doubling the household size need not increase the consumption expenditure twofold to maintain the same standard of living. Using households’ per capita expenditure from the Household Expenditure Survey 2004-2005, we estimate the household size economies indices for household consumption goods through the Seemingly Unrelated Regression. The results suggested that the lower income households enjoy savings from a wider range of public goods compared to the higher income households.Household size economies, Seemingly Unrelated Regression, household composition, public goods, Malaysia.
