Process for determining excitants, attractants and stimulants for members of the procambrus clarkII species of the class crustacea, and method for exciting and/or attracting and/or stimulating members of the procambrus clarkII species of the class crustac

A process for attracting a member of the Procambrus clarkii species of the Class Crustacea from a volume of water inhabited by said member of the Procambrus clarkii species of the Class Crustacea to a desired surface or volume within a body of water comprising the step of applying an aqueous solution containing a Crustacea-attracting concentration of material selected from the group consisting of:

• (i) N-acetyl-D-Glucosamine, an epimeric mixture of compounds having the structures:
• ##STR22## (ii) trimethyl amine oxide hydrate having the structure:
• ##STR23## (iii) "raw sugar", a mixture of sucrose and impurities to the vicinity of said desired surface or volume.

The process of claim wherein the Crustacean-attracting material is N-acetyl-D-Glucosamine, an epimeric mixture of compounds having the structures:

• ##STR24##
