Controlling invasive crayfish – Video

Video credit: Andres Delgado (Colombia) Review: Abdel Rahman El Gamal (Founder of the video channel)

The video shows a single specimen of red swamp crayfish, Procambarus clarkii while climbing a pond dyke and possibly seeking a nearby body of water while the last part of the video shows the sorting of crayfish from the harvest.

I believe that controlling crayfish biomass is a realistic title than eradicating. These animals are capable to avoid most harvesting gears especially while digging their tunnels in the dykes as well as their ability to move out of water.

Trapping has been used to reduce the crayfish population with some success. Also, drain-drying would be able to help in controlling their biomass. Because these animals are not considered food fish in some locations and fishermen may through the caught crayfish back in the water, it is believed that promoting the consumption of crayfish and would lead to careful harvesting and so achieving some control of their populations, bearing in mind that the full eradication of crayfish would be almost impossible.
