Embodiment 1

[0037] A polyculture and domestication facility for fish with different grades and specifications, comprising a culture pond 1, at least two fixed and fixed screens 2, at least two sets of columns 3 and slots 4, two bait feeders 5, two aerators 6, two block sunshade net 7 and two energy-saving lamps 8,

[0038] The interior of the culture pond 1 is installed in parallel with at least two fixed screens 2 in sequence from left to right to form at least three culture areas, and each fixed screen 2 and the side wall of the culture pond 1 leave a 10-30% culture pond respectively. width gaps, each gap is arranged in a staggered order;

[0039] A set of columns 3 and slots 4 corresponding to each other are arranged at both ends of the gap;

[0040] The adjacent three sides of the fixed block 2 are respectively fixed on the bottom surface and the side wall of the column 3 and the culture pond 1;

[0041] The column 3 is provided with a retractable movable block, the fixed side of th...

Embodiment 2

[0045] In this embodiment, the polyculture of large freshwater fish, carp or grass carp and crucian carp is an example in the domestication facility of polyculture of fish with different grades and specifications.

[0046] A kind of fish polyculture domestication facility throwing and feeding method of different grades and specifications, its step is,

[0047] (1) Select a culture pond 1 of 10 mu, set the culture pond 1 according to the method of embodiment 1, and install three fixed nets 2 in parallel in the middle of the culture pond 1 to form four cultivation areas, and each fixed net 2 is connected to the culture pond respectively. A gap of 20% of the width of the culture pond is left on the side wall of the pool 1 for fish to swim back and forth, and each gap is arranged in a staggered order to form a labyrinth-like structure;

[0048] (2) The mesh sizes of the three fixed screens 2 decrease along the culture pond 1 from left to right; the mesh size of the left fixed scre...

Embodiment 3

[0063] In this embodiment, the polyculture of special famous and precious freshwater fish, and the polyculture test of red catfish and yellow catfish in the domestication facilities of polyculture of fish with different grades and specifications are taken as an example.

[0064] A kind of fish polyculture domestication facility throwing and feeding method of different grades and specifications, its step is,

[0065] (1) Select a culture pond 1 of 12 mu, set the culture pond 1 according to the method of embodiment 1, and install four fixed nets 2 in parallel in the middle of the culture pond 1 to form five cultivation areas, and each fixed net 2 is connected to the culture pond respectively. A gap of 15% of the width of the culture pond is reserved on the side wall of the pond 1 for the fish to swim back and forth, and each gap is arranged alternately in turn to form a labyrinth-like structure;

[0066] (2) The mesh size of the four fixed screens 2 decreases along the culture p...

Abstract

The invention discloses a hybrid breeding and domesticating facility of different grades and specifications of fishes, and further discloses a feeding method of the hybrid breeding and domesticating facility of the different grades and specifications of fishes. The hybrid breeding and domesticating facility has the advantages that the fishes can be fed with feeds meeting the requirements of the fishes for nutrients in a hybrid breeding pond respectively, and a good breeding effect is realized; the problem that weak and small fishes cannot fight for food can be effectively solved; the purpose of fishing different specifications of fishes in the hybrid breeding pond can be effectively realized; by establishing a labyrinth type breeding area and setting the size of mesh of a blocking net, theproblem of rebounding after subarea feeding in the hybrid breeding pond can be effectively solved, and it is avoided that large fishes kill and devour small fishes; by adding sunshade net energy-saving lamps, planktons are induced, and famous and precious fishes can be effectively domesticated to accept matched feeds.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a polyculture and domestication facility for fish with different grades and specifications. The invention also relates to a method for feeding fishes of different grades and specifications in a polyculture domestication facility. Background technique [0002] In the process of fishery and aquaculture, due to the single type or group of cultured species, low biological diversity, short food chain, and low ecological stability, the circulation process of the water area is disordered and the ecological imbalance is caused, and the environment is likely to deteriorate for a long time. Therefore, the modern aquaculture industry emphasizes diversified farming, polyculture of fish of different grades and specifications, and new farming techniques of different farming models. Polyculture is based on the biological characteristics of fish, so that fish with different habi...
