The current study deals with the physicochemical characterization, temporal variability and trophic state evaluation of a post glacial mountain lake in eastern Himalaya during the period of 2014-2016. Notable seasonal variations are recorded for physicochemical parameters of lake water. The values for electrical conductivity, total suspended solids, total dissolved solids, total alkalinity and ...

—Populations of lake trout Salvelinus namaycush in Lake Superior collapsed in the late 1950s due to overfishing and predation by sea lampreys Petromyzon marinus. A binational effort to restore the lean morphotype of lake trout began with the stocking of hatchery-reared fish followed by the chemical control of sea lampreys and closure of the commercial fishery. Previous comparisons of the contem...

In this study, otolith morphology and otolith contour from big-scale sand smelt, Atherina boyeri were analyzed in Lake Eğirdir and Lake İznik (natural lakes), and Hirfanlı Dam Lake (artificial lake). The otolith contour and sixteen otolith morphological characters such as width, depth, shape, sulcus acusticus shape, ostium, cauda, rostrum size-shape, and thickness, antirostrum size-shape, and t...

The Great Lakes region of East Africa, including Lake Victoria, is the center of diversity of the mega-diverse cichlid fishes (Perciformes: Teleostei). Paleolimnological evidence indicates dramatic desiccation of this lake ca. 18,000-15,000 years ago. Consequently, the hundreds of extant endemic haplochromine species in the lake must have either evolved since then or refugia must have existed, ...

While the Otsego Lake watershed supports a large diversity of fish species, the list present in the watershed has been continuously updated since the original publication by McWatters (1980,1983). New species have been documented by Hayes and Foster (1989), Foster (1989), Foster and ColIura (1990), and Brooking ( 1991) and the extinction of a species has also been reported by Lehman el al., (19...

Fish were collected from four sites on Otsego Lake on 3 and 4 August 98 to describe littoral populations and diversity and to make a comparison with a similar study conducted in 1986. A haul seine was used to catch the fish, which were marked, weighed, measured and released. The Peterson mark-recapture method was used to estimate abundance at the four sites. Margalefs diversity index was used t...
