Carassius gibelio is anallogynogenetic fish species, which was introduced into Greek lakes during the late 1970s. The values of the exponent b of the length-weight relationships ranged from 2.33 to 3.38, and varied with the trophic state of the lake. In eutrophic lakes these b values were significantly (P < 0.001) lower than in oligotrophic or mesotrophic lakes. Relationships between the b values and phosphorus concentrations were logarithmic: b = 1.37-0.13 log (PO4-P); total length, fork length and standard length were linear (in all cases: r2 > 0.95). In most of the lakes, populations consisted of females, with the exception of Pamvotis, Doirani and Koronia lakes where a small proportion were males. {\textcopyright} 2006 The Authors Journal compilation {\textcopyright} 2006 Blackwell Verlag, Berlin.}, keywords = {Pisces}, author = {Tsoumani, M. and Liasko, R. and Moutsaki, P. and Kagalou, I. and Leonardos, I.} } @proceedings {10120, title = {Natural distribution of the Adriatic sturgeon (Acipenser naccarii) and efforts to recolonize extinct stocks in Greece}, year = {2002}, month = {22-25.5.2002}, pages = {122}, address = {Thessaloniki}, keywords = {kape pisces}, author = {Paschos, I. and Perdikaris, C. and Kagalou, I. and Leka, E. and Tsoumani, M. and Nathanailides, C.} } @article {10121, title = {Gametic products and allozyme variation of brown trout (Salmo trutta) in Louros river (NW Greece)}, journal = {BiologiaBiologia}, volume = {56}, number = {2}, year = {2001}, note = {Export Date: 6 September 2006Source: ScopusReferences: Allendorf, F., W. \& PHELPS, S.

Fish samples are considered as one of the most indicative factors, in freshwater systems, for the estimation of trace metals pollution potential. Lake Pamvotis (NW Greece) is a typical Mediterranean ecosystem of great importance in regard to biodiversity and to aesthetic value. The fish species found most commonly in the lake are Cyprinus carpio, Silurus aristotelis, Rutilus ylikiensis, and Carassius gibelio. The aim of the present study is to evaluate the level of contamination of two essential heavy metals (copper and zinc) appearing at high concentrations in lake water in the above four fish species. Metal concentrations were measured by atomic absorption spectroscopy in three different tissues (muscle, liver, gonads) in order to assess the fish contamination. A two-factor analysis of variance, based on the procedure of general linear models, was employed in which fish species (four levels) and fish tissue (three levels) were examined for potential influence on Cu and Zn concentrations. Differences between level means per factor were treated using Tukey{\textquoteright}s multiple comparisons of means. The study showed that C. carpio and R. ylikiensis presented the highest metal content. Tissues analysis revealed that liver and gonads accumulated the highest levels of Cu and Zn.

The lake has been recognized as an internationally important conservation Site under European Community legislation due to its rich biodiversity. However, during the last three decades the trophic status of the lake has changed as a result of anthropogenic activity (among others irrigation and domestic sewage discharge), resulting in serious problems. Here we present data about the long-term development in eutrophication of Lake Pamvotis. Water samples were collected and analyzed (water temperature, pH, dissolved oxygen, nutrients, chlorophyll-a) during three monitoring periods: 1985-1989, 1998-1999, 2004-2005. The high nutrient concentrations in the lake water during the three monitoring periods, as well as its eutrophic to hypertrophic status reflect the degree of impact anthropogenic activity has had on the lake. Commencement of a restoration plan in 1995-1996, involving sewage diversion, led to a reduction in external nutrient load and consequently to lower in-lake nutrients and Chlorophyll-a concentrations. Orthophosphate concentration decreased by about 87\%, nitrates fell below 1.20mg/l, whilst the total reduction of inorganic N compounds showed a weaker downward trend, fluctuating between 0.39 and 1.24 mg N/l with an average value of 0.76 mg N/l. However, after a short-term recovery the eutrophic status of the lake remains eight years later (2004-2005), suggesting the importance of the internal loading process and the absence of the top-down effect of fish. This study provides evidence for the need of greater restoration efforts utilized in Mediterranean shallow lakes. (C) 2007 Elsevier Ltd.

Organic load, as expressed by the chemical oxygen demand, affected cyanophyte biomass in the lake while temperature was the most important factor for ehlorophyte abundance. Organic load also affected the abundance of zooplankton, but no relationship was found between the concentration of dissolved oxygen and zooplankton.}, keywords = {freshwater}, author = {Kagalou, I. and Petridis, D. and Tsimarakis, G.} } @article {7145, title = {Seasonal fluctuation of zooplankton abundance of lake Pamvotis(Greece)}, journal = {Proc.
