The role of exploitation in altering the processes regulating crayfish populations

Abstract
This paper examines the population dynamics of two crayfish populations. Initially, both populations had similar dynamics. However, following the exploitation of one population, the annual production of the two populations unexpectedly diverged. In the unexploited population, maturing males regulated the growth/mortality rates thus restricting the subsequent recruitment of juvenile stage crayfish. In the exploited population removal of adult males allowed pre-recruitment survival rates to increase. The result was an expansion despite increased trapping pressure. Placing restrictive sex and size limitations on crayfish harvest inhibited population growth causing the populations to destabilize.
