Collected Evidence: Collected Evidence: Procambarus crayfish control: Trapping and removal One controlled, replicated study in Italy found that baiting traps with food (tinned meat) trapped the most red swamp crayfish compared to the use of male and female pheromones or the control (no bait). Over half of all crayfish caught were found in traps baited with food.  Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1029https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1029Fri, 03 Jul 2015 15:14:42 +0100Collected Evidence: Collected Evidence: Procambarus crayfish control: Trapping combined with encouragement of predators A before-and-after study in Switzerland found that introducing predators, combined with trapping significantly reduced red swamp crayfish populations in a pond. A second replicated, controlled study from Italy demonstrated that trapping and predation in combination was more effective at reducing red swamp crayfish populations than predation alone.  Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1031https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1031Fri, 03 Jul 2015 15:16:05 +0100Collected Evidence: Collected Evidence: Procambarus crayfish control: Sterilization of males One replicated laboratory study in Italy found that exposing male red swamp crayfish to X-rays reduced the number of offspring they produced by 43%.  Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1032https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1032Fri, 03 Jul 2015 15:16:20 +0100Collected Evidence: Collected Evidence: Procambarus crayfish control: Remove the crayfish by electrofishing No evidence was captured on the effect of electrofishing as a control tool for Procambarus crayfish.

A study in the Netherlands found that manual removal of mature skunk cabbage plants was effective for a small outbreak of a small-growing plant. A study in Germany reported that after the first four years of a twice yearly full removal programme of skunk cabbage, a large number of plants still needed to be removed each year.
