Prediction of lake trout (Salvelinus namaycush) presence in low-alkalinity lakes near Sudbury, Ontario by Michael Conlon( Book )

1 edition published in 1992 in English and held by 1 WorldCat member library worldwide

Surveys of 30 low-alkalinity lake trout (Salvelinus namaycush) lakes near Sudbury, Ontario, were conducted to assess factors that affect lake trout presence under acidification stress. At the time of the surveys the lakes varied widely in pH (4.5-6.9), concentrations of toxic metals (Al 12-300 mu g/L), and the status of lake trout populations (extinct-abundant). Fish community structure (species richness, species assemblages) reflected and was readily predicted from measured water quality variables. A PCA factor composed of pH, alkalinity, and conductivity was the variable that best predicted lake trout presence (correct discrimination (> 92%)). The results of this study provide managers with easily obtainable predictors for monitoring lake trout status under changing levels of acidic deposition

Dynamics in year-class strength, growth, and calcified-structure size of native lake trout (Salvelinus namaycush) exposed to moderate acidification and whole-lake neutralization by J. M Casselman( Book )

1 edition published in 1992 in English and held by 1 WorldCat member library worldwide

Accurate age-interpretation techniques were developed, using scales and otoliths, to examine the role of whole-lake neutralization in the resurgence of a lake trout (Salvelinus namaycush) fishery in Nelson Lake (pH 5.7) near Sudbury, Ontario. Calcified structures and data from 860 lake trout were collected from 1972 to 1987. The population was characterized by the regular cyclic occurrence of strong year classes, which were probably an effect of pulse angling, cyclic food abundance, and possibly intraspecific interaction. Otoliths grew significantly larger and more translucent and exceeded relative growth of scales and body for all ages in 1976 (18% greater) and for the 1976 year class, confirming that otolith accretion can come from the ambient water because liming increased the calcium content by 33% that year, the only observed direct effect of the treatment
