Conservation Evidence: Evidence Data

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.
