The paper is part of a broader study which aimed to analyze of abiotic and biotic characteristics from areas bordering the Galbeni Lake. Keywords: algal flora, Galbeni Lake Introduction Sample 3 – middle area of the lake The Galbeni Lake - Bird special protection Each sample sums of 6 samplings. area, situated at the confluence of rivers Bistriţa and Siret, since May 2006 is in custody of the Regional The soil profiles were made on these points: Ecology Center Bacău. Perimeter area is Sample 4 – left side of the lake, near dam approximately 6300 meters and widths between 800 Sample 5 – left side of the lake, in its middle area and 1100 meters; surface areas is 1123 hectares. Sample 6 – holm Bistriţa River (Ruşi Ciutea Lake area were initially identified 168 bird village – Bacău county) species, including 74 species of shore habitats, 62 Sample 7 – right side of the Siret River (Ruşi species characteristic of coastal habitats and 32 Ciutea village – Bacău county) species on lake. Water samples were taken as: Sample 8 –Siret River – middle area of the lake Material and method Sample 9 –Bistriţa River, upstrem lake (Ruşi I. Numbers and location of sampling stations Ciutea village – Bacău county) Sampling points were established by Sample 10 – Siret River, upstrem lake (Ruşi identifying potential sources of supply the algal Ciutea village – Bacău county) flora, in terms of habitat restoration by filling the basin. Such were sampled from lenses ecosystems II. Processing the material collected found in the lake basin area flooded (barrier basin) and the water courses wich will supply the lake Each phytoplankton sample volume was 1950 (Siret river and Bistriţa river - tributary Siret river). ml. The samples were fixed with formalin solution To obtain exact information as algal flora of concentration 4%. After settling were concentrated ponds future, I collected soil samples of soil profiles by siphoning and then analyzed using optical of future river banks. microscope combination: eyepieces 10X and objective 40X. Algae present in lenses ecosystems have been Phytoplankton volume of each sample was identified in these samples: 1950 ml. Sample 1 – area near the dam The samples were fixed with formalin Sample 2 – secondary process water dam area solution concentration 4%. After settling were ____________________________________________________ concentrated by siphoning and then analyzed using * “Ion Borcea” Natural Science Museum Complex, Aleea optical microscope combination: eyepieces 10X and Parcului street, no. 9, Bacău. 7 http://www.studiisicomunicaribacau.ro / https://biblioteca-digitala.ro objective 40X. Have made qualitative and Cyanobacteria, Euglenophyta, Chromphyta quantitative determination of algal flora. (Xanthophyceae şi Bacillariophyceae classes), To determine the density of algae was used Chlorophyta, totalig 55 genus. formula: (Phd. Ioan Cărăuş): The quantitative determinations have show hight rate of species held in class Bacillariophyceae, ANC compared with other species of algae observed. D = Data on the density of algae in samples of work nB04,050,0 are presented in graphical form in appendices paper. D - numerical density of phytoplankton I. Determinations in water samples (Table 1) (specimen/ml) In water samples were identified 31 genera C - number of microscopic fields containing of algae. The sample number 8 was collected from microscopic slide Siret river. Most specimens of algae were identified N - number of algae found in the area examined in this sample, the nunerical standpoit and microscopic slide systematically. The large number of species is A - sample volum after siphoning (ml) correlated with a reduced number of individual B - initial volume of sample collected (ml) representatives. N - number of microscopic fields examined High density of planktonic algae present in 0,5 - diameter of
