impacts:
|
unknown
|
crabs can
- burrow holes in banks and levees contributing
significantly to erosion rates and bank instability
- eat the
shoots of plants threatening crops in agriculture
(additionally, diked
fields may be endangered by the collapse of levees triggered by the crab’s
burrows)
- clog the intake
pipes of power plants and irrigation systems by sheer numbers
- damage catch by direct consumption and the nets or traps (when
the
crabs cut the threads with their claws) impacting commercial fisheries
- steal bait impacting recreational fishing
- facilitate a parasite, the Oriental lung fluke (Peragonimus
westermannii) with the possible transfer to humans/other mammals
- presumably have an ecological effect, no impacts are yet
reported
