Stomach Contents Analysis

To determine what the shrimp are eating.

Equipment Required: Scissors and forceps. Clean glass slides and cover slips. 2.5% saline solution. Compound microscope with 10x eyepieces and 4x and 10x 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 dorsal cuticle from just behind the eyes to the end of the carapace to expose the stomach and hepatopancreas. With the forceps grasp the posterior of the stomach and gently lift up and separate from the heapatopancreas. Sever the esophagus and remove the stomach. Open the stomach along the dorsal mid-line and transfer a drop of the stomach contents to a clean glass slide. Add saline solution and cover with a coverslip. Examine under 10x and 40x magnification for the following:

  • Relative percentage of feed pellet present

  • Relative percentage of detritus present

  • Other observations
