ABSTRACT:
Described is a process for determining excitants, attractants, incitants and stimulants for members of the Penaeus genus of the Class Crustacea including but not limited to Penaeus setiferus, Penaeus aztecus and Penaeus vannamei, as well as apparatus for carrying out such process. The apparatus for carrying out the process includes static tank means, flow-through tank means and Y-maze means each equipped with variable-focus camera means taken alone or in combination with one another. The variable-focus camera means platform is also described and is part of our invention. Also described is a method for exciting and/or attracting and/or stimulating and/or inciting members of the Penaeus genus of the Class Crustacea including but not limited to Penaeus setiferus, Penaeus aztecus and Penaeus vannamei (referred to collectively as Penaeus spp.) using various solutions of molecules including but not limited to N-acetyl-D-Glucosamine which is an epimeric mixture of isomers having the structures: ##STR1## as well as feeding compositions for feeding members of the Penaeus genus of the Class Crustacea including (i) prior art feeding compositions and admixed therewith (ii) Crustacea Class-exciting and/or attracting and/or stimulating and/or inciting amounts and concentrations of excitants, attractants, stimulants and/or incitants which include molecules including but not limited to the compound having the structure: ##STR2##
