Abstract
Abstract A fishpond system for the controlled feeding and sorting of fish which consists of a plurality of ponds of sector-shaped outline arranged in two semicircular clusters around two spaced retrieval pits located on opposite sides of a fish-sorting cabin. The two retrieval pits accommodate retrieval baskets which, after being loaded with water and fish, are transferred to the sorting cabin by means of a hoist and cableway.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
204 words
A fishpond system for the controlled feeding and sorting of fish, comprising in combination: a. a plurality of ponds having each a geometric outline with a water supply side and an outlet side; b. pond outlet means on said outlet side of at least one of said ponds for the removal of fish and water from said pond; c. retrieval means adjacent said outlet side to hold fish and water when they are removed from said ponds through said pond outlet means; d. a retrieval basket as part of said retrieval means, said retrieval basket having a retrieval position adjacent a lower portion of said ponds for communicating with said pond outlet means so that, when fish and water are removed from said ponds through said pond outlet means, they pass into said retrieval basket; e. transfer means to move said retrieval baskets from said above said ponds and then to a fish-sorting means; f. said fish-sorting means stationed in the vicinity of said ponds and said discharge position to sort the fish into predetermined categories; and g. said fish-sorting means including fish chute means linking said fish-sorting means to selected ones of said ponds to permit returning of the fish to said ponds.
Claim 2
Dependent Claim
204 words
A fishpond system for the controlled feeding and sorting of fish, comprising in combination: a. a plurality of ponds having each a geometric outline with a water supply side and an outlet side; b. pond outlet means on said outlet side of at least one of said ponds for the removal of fish and water from said pond; c. retrieval means adjacent said outlet side to hold fish and water when they are removed from said ponds through said pond outlet means; d. a retrieval basket as part of said retrieval means, said retrieval basket having a retrieval position adjacent a lower portion of said ponds for communicating with said pond outlet means so that, when fish and water are removed from said ponds through said pond outlet means, they pass into said retrieval basket; e. transfer means to move said retrieval baskets from said above said ponds and then to a fish-sorting means; f. said fish-sorting means stationed in the vicinity of said ponds and said discharge position to sort the fish into predetermined categories; and g. said fish-sorting means including fish chute means linking said fish-sorting means to selected ones of said ponds to permit returning of the fish to said ponds.
Claim 3
Dependent Claim
50 words
A fishpond system as claimed in claim 1, said retrieval basket including a fish container with an opening through which to receive fish and water, said retrieval basket further including overflow means so arranged that excess water is permitted to flow from fish container, while the fish are retained therein.
Claim 4
Dependent Claim
48 words
A fishpond system as claimed in claim 1, said retrieval means further including a retrieval pit arranged adjacent to the outlet side of at least one of said ponds, said retrieval pit being shaped to accommodate said retrieval basket in a retrieval position below said pond outlet means.
Claim 5
Dependent Claim
41 words
A fishpond system as claimed in claim 3, said means to transfer including lifting means to lift said retrieval basket out of said retrieval pit, and Translation means to move said retrieval basket from said retrieval pit to said fish-sorting means.
Claim 6
Dependent Claim
28 words
A fishpond system as claimed in claim 1, said fish chute means including a discharge end which is displaceable, thereby selectively linking said fish-sorting means to different ponds.
Claim 7
Dependent Claim
21 words
A fishpond system as claimed in claim 2, said plurality of ponds being arranged in a cluster around said retrieval pit.
Claim 8
Dependent Claim
66 words
A fishpond system as claimed in claim 6, said geometric outline of said ponds having the shape or a circular sector, said ponds being arranged in a radial cluster around a cluster center, and said retrieval pit being of a circular shape and located substantially on said cluster center, so that said outlet sides of said ponds are spaced around the periphery of said retrieval pit.
Claim 9
Dependent Claim
41 words
A fishpond system as claimed in claim 7, said ponds being arranged in two semicircular clusters around two spaced circular retrieval pits, said semicircular clusters facing one another; said fish-sorting means further including a sorting cabin located between said retrieval pits.
Claim 10
Dependent Claim
116 words
A fishpond system as claimed in claim 7, said ponds including a concrete pond bottom sloping toward said retrieval pit, vertical partition walls of prefabricated concrete forming a common sidewall of two adjacent ponds, an outer vertical wall of prefabricated concrete forming the outer periphery of said cluster and the supply side of said ponds, and an inner vertical wall of prefabricated concrete forming the outlet side of said ponds; said pond outlet means including a separate outlet for each pond and a corresponding gate valve to open and close said outlet; each of said ponds further including a pond drain with a drain gate valve and means to control the water level inside the pond.
