Samples were collected fortnightly for the period of three month. The objectives were to determine the physico-chemical parameters, assess the phytoplankton abundance and the relationship between physico-chemical parameters and phytoplankton abundance of the river. Phytoplankton was determined following the method described by Lee and Cundy and Anene. Physicochemical parameters were determined following the method described by APHA. The mean values of the physico-chemical parameters recorded include Air temperature (29.6±1.04), water temperature (26.8±0.86), Water pH (8.09±0.33), Turbidity and Transparency (10.17±0.66), water velocity (0.29±0.04) Dissolved oxygen (3.3±0.24) and electrical Conductivity (84.6±4.12). A total of 717 individuals and 21 species of phytoplankton’s were recorded. The dominant phytoplankton was Bacillariophyceae (46.03%), followed by order Chlorophyceae (30.82%), Cyanophyceae (15.48%) and Euglenophyceae (7.67%). The total number of phytoplanktons varies with month of sampling; a higher number was experienced during the rainy seasons. Pearson correlation co-efficient shows physico-chemical parameters are responsible for sharpening the structure of phytoplankton abundance. ANOVA and Simpson’s index (D) method was used to analyze the data.</p> H. S. Kiman, A. A. Kawu, R. A.

The various experimental coops were labelled in accordance with their experimental treatment as paper crates (T1), vegetable oil (T2) and saw-dust (T3). Each treatment (T) had three replications (20 eggs per replicate), which gave a total of nine replications. Data collected were analyzed using General Linear Model (GLM) procedure of SAS.</p> <p><strong>Results: </strong>Results showed that egg storage methods had significant (P &lt; .05) effect on egg weight after storage, egg weight loss and embryonic development. The highest (P &lt; .05) egg weight after storage was observed among eggs stored with vegetable oil and lower among eggs stored on paper crates. Eggs treated with vegetable oil produced very excellent (P &lt; .05) results with lower weight loss while eggs stored with paper crates recorded the highest weight loss. Embryonic development was significantly (P&lt; .05) higher among eggs treated with vegetable oil followed &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;by saw-dust with paper crates being the least. Albumen weight and yolk weight was significantly (P &lt; .05) higher among eggs treated with vegetable oil. Similar (P &lt; .05) albumen weight was observed for both saw-dust and paper crates. The least yolk weight was observed among eggs stored on paper crates.</p> <p><strong>Conclusion: </strong>In conclusion, coating table eggs with vegetable oil could be effectively used to preserve egg quality and improve embryonic development.</p> Patrick Atta Poku .
