Catch data derived from artisanal fishery and collected from October 2017 to December 2018 have been used to estimate sixty-four fish and other fishery resources abundance in connection with the fishing gears with which they had been caught. These gears deployed in continental shelf waters of Côte d’Ivoire by the fishers included the drifting gillnet, stationary gillnet, bottom gillnet, beach seine, purse seine and longline. The results indicated differences in the abundance of each species relating to the gear type. Some species were caught with one fishing gear while others were vulnerable to at least two gears. Additionally, some pelagic species, of which the Sardinellas (e.g. Sardinella aurita Valenciennes, 1847 and S. maderensis (Lowe, 1839)), accounted for the principal species with higher abundance. The drifting gillnet and purse seine proved to be the fishing gears that caught the most specimens, cumulating 43.24% and 34.54% of total number of species landed, respectively. Catches with longline were however more diversified, spanning the pelagic to bottom species. The study also described the environmental conditions of these species through the change in temperature and phytoplankton abundance due to the change in season, which indirectly contributed significantly to varying abundance of species.

In current study, the morphology of copper (II) oxide nano-material was evaluated using, ethylene diamminetetraacetate as soft template via low temperature aqueous chemical growth technique. Scanning Electron Microscopy (SEM) was used to investigate the morphology of copper (II) oxide nanostructures and freshly developed CuO was observed to have spherical shape. X-ray Diffraction (XRD) method was used to study the crystalline quality of cuperic oxide which showed crystalline nature of high quality. Three types of bacteria and one type of fungi were selected to facilitate the antimicrobial activity of synthesized nanostructures. In this work it was declared that as concentration of CuO increases the inhibition zone also increases for all the three types of bacteria and fungi too. At the concentration of 1.0mg/L the inhibition zone found was as given below: pergillusniger>15.41mm, Agrobacterium tumefaciens> 21.5mm, Klebsiella pneumonia >23.6mm and E.coli>28.6mm. It was further found that E. coli was extra responsive to copper oxide.
