A Comparison of the Effect of Blast Chilling and Electrical Stunning on Some Hemolymph Parameters in Red Swamp Crayfish (Procambarus Clarkii)

The aim of the present investigation is to compare the effect of standard method and electrical stunning on some hemolymph biochemical parameters in mid-sized Red Swamp Crayfish. The results showed that electrical stunning time of induction was significantly shorter and recovery was longer than chilling stun. Parameters of an electrical field that stuns crayfish beyond the point of recovery without causing damage have been identified. Based on this experiment, it seems that electrical stunning would be preferable to the other method.
