    Notes: Juvenile rainbow trout demonstrated recognizable differences in their ability to assimilate useable energy from food organisms at three different water temperatures. This paper describes the technique and computations used to document these differences and discusses possible reasons for such differences.

    Approaches to the analysis of energetic costs of intraspecific competition for space by rainbow trout (Salmo gairdneri) (1977)

    Notes: Two approaches of estimating energy expended by rainbow trout (Salmo gairdneri) on density-dependent activities were tested. Metabolic rates were obtained from growth experiments in laboratory systems. Increases in metabolic rates at higher population densities were attributed to three factors: (1) starvation, (2) increased levels of exercise by subdominant fish were forced to maintain stations in fast water due to saturation of territories of more dominant trout, (3) higher planes of excitation. It was observed that variance of energetic factors of routine metabolism, growth rate, consumption rate, and growth efficiency tended to increase with density. These responses seem to be a good indication of intraspecific competition. Little correlation was observed between density and average daily ration, or density and aggressive behaviour.Dominant trout, as a group grew faster, grew more efficiently, and contained greater lipid content than the rest of the population at each density. However, strictly defined, energetic advantages were not conferred on a ‘peck-right’ basis. At higher densities, dominance conferred less benefits than was observed at lower population levels. Space limitation per se was not an influential factor affecting growth rates. Methods used to estimate density-dependent energy costs are evaluated. Both methods give nearly identical estimates.

    Terrestrial liming as a tool to mitigate acidification of woods lake, NY (1990)
    Springer
    Water, air & soil pollution 54 (1990), S. 509-527

    Notes: Abstract The Soil Liming Model (SLiM) has been used to simulate lake and stream water quality response to different strategies for the application of limestone to subcatchment soils in the Woods Lake, NY watershed. Simulations using doses of 3, 10, or 30 t ha−1 forecast that a dose in excess of 10 t ha−1 must be applied to discharge areas in order to sufficiently improve water quality in the lake. At 3 t ha−1 inlet stream water quality could support fish populations. As expected, treatment effectiveness is strongly influenced by subcatchment hydrologic flow paths. Where shallow flow predominates, soil liming provides a more effective tool for lake water quality improvement. In subcatchments drained primarily by ground water, the effect of liming on water quality is less pronounced albeit of longer duration. Based upon the results of these model simulations, the authors compare results of conventional lake liming to simulated watershed treatment predictions.

    Dose-response relationships for the addition of limestone to lakes and ponds in the Northeastern United States (1988)

    Notes: Abstract A titration based model (DeAcid) has been used to predict treatment dose and times for reacidification for CaCO3-treated lakes in the Living Lakes, Inc. (LLI) aquatic liming program. Water quality constitutents (pH, ANC and Ca) were used to measure the effectiveness of the dosing model and reacidification rates. Data from 22 lakes or ponds in 5 northeast states have been collected since June 1986. With few exceptions, pH and ANC values ranged from 4.5 to 6.5 and −30 to +65 ueq L−1, respectively, in untreated sites and 6.5 to 7.8 and 120 to 300 ueq L−1, respectively, in sites approximately 30 days after treatment. Changes in Ca concentration levels have been used to evaluate the utility of the dose model for treatment of both inland and coastal waters. For coastal, seepage lakes application of a single-box mass transfer model to observed post-liming changes in ANC and Ca adequately simulates lake response.

    Notes: Abstract An intergrated, international cooperative program has been initiated to manipulate two watersheds. This will include soil liming and/or fertilization of two watersheds, one in New York State and another in the Black Forest of West Germany. A description of the watersheds and approach is documented in this paper.

    Living lakes: An aquatic liming and fish restoration demonstration program (1988)
    Springer
    Water, air & soil pollution 41 (1988), S. 85-93

    Notes: Abstract Living Lakes, Inc. (LLI), a not-for profit organization, sponsors an applied aquatic resources restoration demonstration program for acidified waters. In 1986 and 1987 LLI began evaluation of seven different liming technologies on 22 lakes and 10 streams in 6 states. Lakes and streams have been treated in the states of Massachusetts, Rhode Island, New York, Pennsylvania, Maryland and West Virginia. The Living Lakes program commits to ongoing water quality analysis for the lakes and streams treated for the life of the program and, if necessary, retreatment. Living Lakes has recently begun investigations into the treatment of partial or entire watersheds in conjunction with the Loch Fleet project in Scotland, investigations in the Black Forest in Germany, and studies in the Woods Lake watershed in the Adirondack region of the state of New York, co-sponsored by the Electric Power Research Institute.
