Abstract: 

The authors attempted to control a population of papershell crayfish (Orconectes
immunis ) in an 11- hectare fish-rearing impoundment in Jackson County,
Wisconsin, by using traps and by stocking largemouth bass (Micropterus salmoides
). Crayfish were harvested with traps during the summer of 1985, and the pond was
stocked with 386 largemouth bass (mean weight, 1.1 kg) in spring 1986. The pond
was drained in the fall of 1985 and 1986, and crayfish burrow counts were made to
estimate the population. In 1985, more than 18,000 crayfish were trapped, of which
72% were adult males. Trapping had minor effect on the young-of-the-year
crayfish. In 1986, the crayfish population was reduced by 98%, predation by
largemouth bass being the probable major cause of the reduction.
