Abstract
Abstract A mating tank for crustaceans, especially for decapods, having several individual compartments for females, one compartment for a male which adjoins all the female compartments, and movable porous dividing apparatus between male and female compartments for allowing the male to associate with a selected female. Light producing means encourage the females to moult. A method for effecting efficient mating.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
85 words
The method of encouraging the mating of a male crustacean with a selected female of the same species, comprising the steps of: a. isolating at least one female in an individual female compartment, b. isolating said male in a male compartment, c. providing a common water environment between said male and female compartment to permit the sexual attractant given off by a female to reach the male, and d. selectively permitting access between said female compartment and said male compartment when the female becomes fertile.
Claim 2
Independent Claim
85 words
The method of encouraging the mating of a male crustacean with a selected female of the same species, comprising the steps of: a. isolating at least one female in an individual female compartment, b. isolating said male in a male compartment, c. providing a common water environment between said male and female compartment to permit the sexual attractant given off by a female to reach the male, and d. selectively permitting access between said female compartment and said male compartment when the female becomes fertile.
Claim 3
Dependent Claim
65 words
The method of claim 1 wherein step (a) includes the step of isolating a plurality of females each one being in a separate compartment; step (c) includes providing said common water environment between each compartment isolating a female therein and the compartment isolating the male; and step (d) includes the step of providing access between only one of said female compartments and the male compartment.
Claim 4
Dependent Claim
42 words
The method of claim 1, in which said female compartment is connected to said male compartment by a passage negotiable by said crustaceans, and in which said step of selectively permitting access comprises the removal of a porous barrier from said passage.
Claim 5
Dependent Claim
27 words
The method of claim 1, comprising the further step of: providing for continuous circulation of the common water environment between said male compartment and said female compartment.
Claim 6
Dependent Claim
22 words
The method of claim 1, comprising the further step of: illuminating said female compartment to provoke frequent fertile periods in said females.
Claim 7
Dependent Claim
27 words
The method of claim 3, comprising the further step of: providing for continuous circulation of a common water environment between said male compartment and said female compartment.
Claim 8
Dependent Claim
22 words
The method of claim 3 comprising the further step of: illuminating said female compartment to provoke frequent fertile periods in said females.
Claim 9
Dependent Claim
22 words
The method of claim 4, comprising the further step of: illuminating said female compartment to provoke frequent fertile periods in said females.
