Research programmes have also operated in the USA (Auburn University, Kentucky State University), Mexico (CIBNOR) and Israel, some of which remain current. These are flushed seasonally with monsoonal wet season rains, which may wash the redclaw downstream. There are loads of business opportunities in the fish and seafood farming industry and crawfish farming is one of them. Redclaw is considered an invasive species, and thus its introduction into many areas outside its natural distribution is considered risky. This slow drainage enables the crayfish to move out of shelters and with the main body of water, so that they concentrate and respond most effectively to the flow trap.
