. Gill Examination Used to assess the physical condition of the gills. Equipment Required: Scissors and forceps. Clean glass slides and cover slips. 2.5% saline solution. Compound microscope with 10x, 40x and 100x eyepieces and 40x and 100x objectives. Procedure: Collect 10 shrimp from the tank and hold live. Sacrifice each shrimp by severing the ventral nerve cord between the body and abdomen (tail). Gently remove the cuticle over one side of the gill chamber, clip off several gill filaments, place on a clean glass slide in a drop of saline solution and cover with a coverslip. Examine under 10x and 400x magnification for the following: Grade of filamentous bacterial infection. Grade of protozoan infection. Grade of detrital and algal fouling. Grade of melanized cuticle lesions. Grade of internal melanized tissue or nodules.
