The prime goals of the present study are to assess trends in the concentrations of the groundwater quality and evaluate this water for domestic, agriculture and various industrial processes. Groundwater quality indicators were monitored, for the first time, for4 years (2011, 2013, 2014 and -2015) from three wells constructed in El-Sheikh Fadl, Bani Mazar, El Minya Governorate, Egypt. Quality indicators included pH, alkalinity, TDS, hardness, Na<sup>+</sup>, k<sup>+</sup>, Mg<sup>2+</sup>, Ca<sup>2+</sup>, Cl<sup>-</sup>, SO<sub>4</sub><sup>2-</sup>, NO<sub>3</sub><sup>-</sup>, S<sup>2-</sup>, Al<sup>3+</sup>, Cu<sup>2+</sup>, Fe<sup>2+</sup>, Mn<sup>2+</sup>and Ni<sup>2+</sup>concentrations.Based on the outcomes, groundwater was classified as brackish water. Elevated pH, alkalinity, Ca<sup>2+</sup>, SO<sub>4</sub><sup>2-</sup>, NO<sub>3</sub><sup>-</sup>, S<sup>2-</sup>, Al<sup>3+</sup>, Cu<sup>2+</sup>, Fe<sup>2+</sup>, Mn<sup>2+</sup>and Ni<sup>2+</sup> concentrations were observed over monitoring years. Three main Varimax-rotated factors counted for 82.53 % of the total variance of the quality variables revealing how process like water-rock interaction, salinization and industrial pollution influence groundwater quality. The groundwater samples have a mixed mineralization that is possibly pure marine water affected by leaching and dissolution and cation exchange of both meteoric water (rainy water containing cement dust) and terrestrial salts. Groundwater is generally supersaturated with respect to calcite, dolomite and aragonite minerals. The water wells are not suitable for drinking and irrigation. For industrial, the groundwater needs further treatment.

The present study was carried out to describe the ovary and oogenesis in the freshwater bivalve <em>Caelatura parreyssi</em> from<br />histological and ultrastructural points of view. Ten adult healthy clams collected from the River Nile were used in this study. The specimens were dissected and gonads were obtained and processed for histological and ultrastructural examination. Histologically, the ovary of <em>C. parreyssi</em> is composed of numerous of follicles which are connected together by connective tissue. Each follicle contains different stages of developing oocytes; oogonia, previtellogenic<br />oocytes, vitellogenic oocytes and postvitellogenic oocytes (mature oocytes). At ultrastructural level, stages of female gametogenesisvwere examined; the process of oocytes formation and yolk deposition were described in successive stages of oogenesis. The structure and function of auxiliary cells and follicle cells in ovarian follicles during vitellogenesis were discussed. In conclusion, this study showed that the follicle cells play an important role during oogenesis but probably are not the major source of yolk precursors. The vesicular connective tissue is probably the main source of nutrients for vitellogenesis. The auxiliary cells appear to play an integrate role in the development of the oocytes as their functions<br />can permit a transfer of precursors necessary to vitelogenesis.

The objective of this study is to investigate the biodiversity of phytoplankton and to identify the algal species as bio-indicators for water quality in Tajan River of Mazandaran Province (North of Iran).<br /> A total of about 600 samples were collected from 9 stations; from Solayman Tange Dam to Caspian Sea during the period 2011- 2017. 305 species under 86 genera and 23 subspecies (totally 328 taxa) were identified under five algal divisions. The highest number of species was belonging to the Bacillariophyta including 71 species, and the lowest was for Streptophyta including 56 species. Also, the percentages of species in different algal divisions were about 21, 20, 22, 20, and 17% for Cyanoprokaryota, Euglenophyta, Bacillariophyta, Chlorophyta, and Streptophyta, respectively. Results showed that order Euglenales had the highest biodiversity (59 species). The Oscillatoriaceae was a dominant family with 3 genera and 35 species, while <em>Oscillatoria </em>was a dominant genus including 22 species. Referring to the stations, the highest number of Cyanoprokaryota was recorded at stations 1 & 2 (48 species), station 7 for Euglenophyta (44 species), station 5 for Bacillariophyta (41 species) and Chlorophyta (52 species), and finally station 2 for Streptophyta with 26 species. With respect to the importance of the Tajan River in north of Iran for drinking and agriculture activities, the results of this study is very important as one of the main criteria for assessing and monitoring of water quality and environment in this region with emphasis on algae interference.

This study was carried out to detect the parasites affecting Japanese threadfin bream (<em>Nemipterus japonicus)</em>. A total of 150 specimens collected from Gulf of Suez- Red Sea in Egypt from November 2016 to April 2017. Specimens were subjected to clinical, postmortem and parasitological examinations for detection of nematode parasites. The clinical examination showed no pathognomic clinical abnormalities on the external body surface except abdominal distension. Postmortem examination revealed excessive mucus secretion and swelling in intestine. Only the endoparasite <em>Hysterothylacium gadi</em> (Müller, 1776) (Nematoda: Anisakidae) was recorded in the intestine and stomach of examined fish. The prevalence rate was 54.7% and the intensity of the infection ranged 1-3 worms per fish. The morphological characteristics of this species were described in details using light and scanning electron microscopy. The results showed that females are larger than males. It is also shown that the cephalic region provided with three hexagonal-shaped lips separated from each other by three prominent interlabium; ventrolateral lips somewhat smaller. Dorsal lip provided on its surface with two double papillae, whereas both ventrolateral lips with one papilla and one small papilla. Interlabila are conical and their base is wider than length (Figs. 1&4). The worm was characterized by a broad lateral alae starting immediately below lips gradually narrowing posterioly and extending as narrow alae along whole body. A groove like structure is seen in the ventral surface of the body (Fig. 9). The tail is conical and tail tips of both sexes provided with numerous conical spines and the male has equal spicules.

The present study was conducted to investigate the distribution of bacteria and selected heavy metals (Al, Fe, Zn, Mn, Cu, Cd, Pb, Co, Ni and Cr) in water samples and in the gills and muscles of the Nile tilapia (<em>Oreochromis niloticus</em>) grown along El- Salam Canal zone. Samples were analyzed by inductively coupled plasma-optical emission spectrometry (ICP-OES). The concentrations of heavy metals in water samples showed the high levels of heavy metals in the studying area. The levels of heavy metals in the fish samples can be considered as a serious matter of concern as it may be consumed and it signifies the degradation of canal quality. Regarding to microbiological analysis, the results showed an increase in some bacterial pollutants which linked with human disease. The counts of pathogenic bacteria <em>Pseudomonas aeruginosa</em> ranged from 80 to 200 MPN/100 ml, while that of Salmonella- Shigella varied from 0 to 30 CFUml and <em>E.coli</em> colony number range from 0 to 10. In addition, the fish caught from the study area revealed the presence of different bacterial species. A total of eight bacterial species were isolated from fish and identified biochemically as <em>Salmonella </em>spp<em>.,</em><em> Enterobacter cloacae</em><em>, </em><em>Rhizobium radiobacte</em><em>.,</em><em> Fluorescens </em>spp<em>.,</em><em> Listeria</em><em> monocytogenes</em><em>,</em><em> Streptococcus agalactiae</em><em>,</em><em> Streptococcus iniae</em> and <em>Aeromonas hydrophila</em>. The bacterial count from each sample revealed 44.5 x10<sup>7</sup> cfug<sup>-1</sup> from the gills, 20 x10<sup>8 </sup>cf ug<sup>-1</sup> from the intestine and 38.75x10<sup>8</sup> cfug<sup>-1</sup> from the skin. The isolates were found to be of medical importance, so restricted measurements should be taken to inhibit the spreading of pollutant sources in El-Salam Canal.

A new trematode species <em>Sclerodistomum aegyptiaca</em> (Hemiuroidea, Sclerodistomidae) was isolated from (50%) out of 120 (50 males and 70 females) Brushtooth Lizard fish collected from the Suez Gulf, Red Sea. Females fish were more infected (64.3%) than males (30%); the total mean intensity was (2.75±1.44), it was (2.26±1.33) in males and (2.9±1.45) in females. The effect of some biological factors (sex, weight) of the host on the infection rate has been studied using statistical analysis. It revealed that there is no significant difference between the infected males and females (P˂0.01). Also, larger fish had more infection prevalence than smaller ones. The new species was studied using light and scanning electron microscope. It is distinct morphologically by the presence of (1) musculated esophageal bulb, (2) extremely short esophagus, (3) the position of gonopore that located very near to acetabulum than the oral sucker, (4) the ovary in the hind body nearer to the posterior extremity than acetabulum, (5) the extension of the uterus (6) the distribution and shape of vitellaria. SEM revealed the distribution of minute spines on the ventral surface of the worm except on the oral sucker and the inner rim of ventral sucker, the presence of different types of papillae, pits, tegumental folds and ridges.

The distribution and abundance of biota in an aquatic environment is generally influenced by environmental parameters. This study was carried out to assess the relationship between environmental parameters and phytoplankton distribution in Lekki lagoon, Sub-Saharan Africa. Phytoplankton and environmental data were obtained from nine stations in three replicates each from January to December, 2016. The relationship between phytoplankton and environmental data was assessed through multivariate analysis using PRIMER v<sub>6 </sub>Software. A total of thirty-seven (37) species from six (6) divisions were recorded which included Chlorophyta, Bacillariophyta, Cyanophyta, Charophyta, Ochrophyta and Euglenophyta. Chlorophyta appeared to be the most diverse division with 14 species, while Ochrophyta was represented by a single species. The highest number of individuals (25809 ind/ml) and species (21) was observed in Station 3, while Stations 8 and 1 ranked least in terms of number of individuals (10038 ind/ml) and species (14) respectively. The nine stations formed two non-significantly (p>0.05) different clusters based on the phytoplankton community and were strongly correlated with transparency, nitrate and total suspended solids combined. The model that best explained the pattern of distribution of phytoplankton among the stations included depth, conductivity, dissolved oxygen, biological oxygen demand, total dissolved solids and total suspended solids. The findings showed that distribution of phytoplankton is influenced by a complex of environmental parameters especially those related to light and nutrient availability.
