The stimulating food intake experiment was conducted in glass aquarium with dimensions of 1008 40* 50 centimeter. The shrimps were released in one side of the aquarium and also food pellets was droped on the other side of aquarium. The number of remaind pellets were accounted after 30 minutes and 2 hours.
