Food Habits, Growth, and Catchability of Grass Carp in the Absence of Aquatic Vegetation

Grass carp (Clenopharyngodon idel/a) were stocked into a 3.6-ha Georgia pond devoid of vegetation to simulate conditions that might occurr in a pond where grass carp have eliminated the macrophytes. The flSh were readily captured by hook-and-line fishing. The stomachs of 417 grass carp contained primarily terrestrial macrophytes; no fish or fish eggs were found. Many of the grass carp examined weighed less than when they were stocked.
