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...

abstract the urmia lake as an important water body in the northwest of iran, recently is faced with a critical level reduction, which makes it important to evaluate the causes. in this regard understanding of the lake's behavior and assessing effect of tele-connections on lake level oscillations is necessary. this subject constructs objective of the present paper that applies the spectral analy...

this study investigated the impact of internal nitrogen and phosphorus loading on water qualityof lake chaohu, china. results showed that the overall mean concentration of tn and tp in lake water was1.09±0.84 and 0.15±0.84 (sd) mg/l, respectively, indicating lake chaohu was highly eutrophic during thestudy period. mean benthic flux of nh4 +, no3 -, and po4 3- were 3.56±1.52 mg n/m2/d, -0.14±0.4...
