Comparative Evaluation of the Effectiveness of some local Fabrics for Zooplankton Harvest
A comparative evaluation of the effectiveness for zooplankton harvest for three local fabrics (a white poplin, 120μm; grey baft, 200μm; a nylon, 235μm) and an imported standard zooplankton net of mesh size 76μm were tested in this study. Mesh sizes and gauze constitution of the fabrics were determin...
