Abstract
Abstract A fish hatching device consisting of a main tank removably supporting a confining mother fish containing housing including a lower auxiliary housing for hatched fish, the two housings being separated by a removable grid and openings in the upper mother fish containing housing for permitting a flow of water thereinto from the main tank. Supported exteriorly of the main tank is a flow and aerating tank divided into two compartments by a removable partition having a screened opening. Water is drawn from the lower end of the auxiliary tank into one compartment and flows through the screen into the other compartment from which the water is returned to the main tank, the water being aerated by means of an electric air pump, the cycle being repeated as long as necessary. The removable grid supports the eggs laid by the mother fish and the auxiliary housing contains the hatched fish. Later the same may be transferred to the main tank when attaining sufficient growth.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
185 words
A fish hatchery device comprising: a. a main tank having end and sidewalls, a bottom and open at its top, b. a mother-fish containing housing, c. bracket means secured to said fish containing housing for supporting the same within said main tank from the edge of one sidewall thereof, d. an auxiliary housing having downwardly tapering walls providing a discharge opening at the lower end of said auxiliary housing, e. said fish containing housing at its bottom and said auxiliary housing at its top being open, complemental in shape and having areas substantially equal to each other, the auxiliary housing constituting a closure for said mother-fish containing housing. f. said auxiliary housing being removably suspended from said fish containing housing from the bottom thereof, g. support means interiorly of said fish containing housing at the bottom thereof, h. a removable mother-fish retaining grid extending across the bottom of said fish containing housing seated on said support means, and i. there being a plurality of openings in the fish containing housing above said grid for the flow of water into said housing from said main tank.
Claim 2
Dependent Claim
185 words
A fish hatchery device comprising: a. a main tank having end and sidewalls, a bottom and open at its top, b. a mother-fish containing housing, c. bracket means secured to said fish containing housing for supporting the same within said main tank from the edge of one sidewall thereof, d. an auxiliary housing having downwardly tapering walls providing a discharge opening at the lower end of said auxiliary housing, e. said fish containing housing at its bottom and said auxiliary housing at its top being open, complemental in shape and having areas substantially equal to each other, the auxiliary housing constituting a closure for said mother-fish containing housing. f. said auxiliary housing being removably suspended from said fish containing housing from the bottom thereof, g. support means interiorly of said fish containing housing at the bottom thereof, h. a removable mother-fish retaining grid extending across the bottom of said fish containing housing seated on said support means, and i. there being a plurality of openings in the fish containing housing above said grid for the flow of water into said housing from said main tank.
Claim 3
Dependent Claim
131 words
The fish hatchery of claim 1 including: a. a water flow and aerating tank mounted on said main tank exteriorly thereof, b. a partition dividing said water flow and aerating tank into a water receiving compartment and a water discharge compartment, c. there being a single large centrally positioned opening in said partition for permitting a free unrestricted flow of water from the water receiving compaRtment into the water discharge compartment, d. first conduit means connected to the discharge opening of the auxiliary housing for conducting water from the auxiliary housing to the water receiving compartment of the water flow and aerating tank, and e. second conduit means including aerating means for delivery of water from the water discharge compartment of the water flow and aerating tank to the main tank.
Claim 4
Dependent Claim
98 words
The fish hatchery device of claim 2 including: a. a syphon bulb means associated with the first conduit means to initiate the flow of water into the water receiving compartment, b. bracket means secured to one wall of the water flow and aerating tank for mounting said tank exteriorly on one end wall of the main tank, and c. spacer lug means secured exteriorly to said one wall of the water flow and aerating tank engageable with said one end wall of the main tank supporting the same whereby to maintain the water flow and aerating tank vertical.
Claim 5
Dependent Claim
103 words
The fish hatchery device of claim 3, wherein said first conduit means comprises a. a water receiving chamber mounted at the lower end of said auxiliary chamber receiving water through the discharge opening thereof, b. a water discharge conduit having one end connected to said water receiving chamber and extending upwardly within said main tank, and c. the upper end portion of said water discharge conduit being arcuately bent to extend over said one end wall of the main tank and with its lower open end positioned in the upper portion of the water receiving compartment of said water flow and aerating tank.
