  • Place the crustaceans in a freezer. Regularly check them for signs of insensibility (see 'Signs of insensibility'). ...
  • Once the crustaceans are showing signs of insensibility, mechanically kill them as soon as possible to ensure that they do not recover.
  • Larger crawfish stressed by low dissolved oxygen climb to the surface on vegetation or traps and expose their gills to higher oxygen levels at the surface (Figure 5). ... When oxygen levels become critically low, crawfish attempt to access the water surface, or may even leave the pond.
