Both for the clear, oligotrophic and green, eutrophic waters, the best set of limnological
conditions that improved Nile tilapia fingerlings growth was the following: pH: 7.4-8.2; total alkalinity > 50 mg [L.sup.-1]; calcium hardness > 140 mg [L.sup.-1] (soluble calcium > 56 mg [L.sup.-1]); free C[O.sub.2] < 7 mg [L.sup.-1].
Such differences suggest that climate may not be the only cue for gamogenesis, and that other environmental stimuli, ecological or limnological
, may also play a role.
study of a bog lake which has never developed a marginal mat.
As might be expected, the Ten-Year Limnological
Study generated many questions that simply could not be evaluated in a ten-year cycle.
Egerton's chapter 5, then, is an overview of "The Wisconsin Limnology Community," in which he analyzes the achievements of these leaders of limnology, comparing and contrasting the evolution of their limnological
program, discussing the similarities and differences in their aims, approaches, methods, and results.
Initially we evaluated the hypothesis that WLF distinctly influence the biomass of the species of aquatic macrophytes and the limnological

studies of River Soan (Iqbal et al., 2006) have reported high water pH, 8.0-9.0 and 7.20-8.20 respectively.

In large reservoirs, these changes in water quality and limnological
characteristics create distinct habitats often forming three distinguishing zones which are riverine zone characterized by the fluvial environment, lacustrine zone nearest to the dam, and a middle transition zone (Tundisi, 1996; Moretto and Nogueira, 2003; Serafim et al., 2006; Sthapit et al., 2008).
study, water samples were collected from all five ponds on fortnightly basis.
