Embodiment 1

[0074] Present embodiment adopts above-mentioned cultivation system and the cultivation method of this system to carry out cultivation, and in the present embodiment, flowing pool 1 is 60 square meters, and the depth of pond water is 1.8 meters, is refitted by idle flowing water fish pond. The set filter screen is trapezoidal, and its area is set to 1 / 2 (2.3+3.3) × 1.8 square meters. It is fixed on the pool wall with a 10 × 6 cm wooden frame around it, and then the filter screen is nailed to the wooden frame with a bead. to fix.

[0075] This embodiment is a productive test. A total of 4 flow pools with the same basic conditions are selected, and the inflow flow rate can be controlled between 0.05-0.08 cubic meters per second. 1#, 2#, and 3# ponds use nylon filter screens of 60 mesh / inch, 120 mesh / inch, and 200 mesh / inch respectively; 4# pond is a control pond without a filter screen, and a no-knot filter with a mesh size of 1.0 cm is used. Polyethylene mesh replaces the stra...

Embodiment 2

[0084] This embodiment is a production test, and the purpose is to detect the effect of the filter screen mixed with feeding fish in running water fish culture. The running pool 1 of the present embodiment is selected as 60 square meters, and the water depth is 1.8 meters, and the nylon filter screen is 200 mesh / inch; other conditions are identical with embodiment 1.

[0085] In the production test of this embodiment, two flow pools with basically the same conditions were selected, and the flow rates were both controlled at 0.05-0.08 cubic meters per second. 30,000 summer flowers of Pengze crucian carp were put into pond 1#, and 30,000 summer flowers of grass carp were put into pond 2#. When the specifications of crucian carp and grass carp reach a total length of more than 2.0 inches, each pool will be put in 14,000 silver carp summer flowers and 6,000 silver carp summer flowers; and hard pellet sinking feed. The above production test is fed by conventional running water fis...

Embodiment 3

[0089] In this example, taking the production test in a freshwater area as an example, a 10-acre pond is upgraded and the water inlet flow is controlled to 0.08-0.12m 3 / s, the water outlet is equipped with a 400 mesh / inch rectangular stainless steel wire filter, which can be taken out for cleaning or replacement at any time. ×8㎡. The mixed culture of silver carp and bighead carp, grass carp, herring and crucian carp is adopted. While feeding feed, the bottom dwelling animal snail is also added to feed the herring freely.

[0090] The feeding situation of fish species in this embodiment: the specification is 1500 silver carp of 8 to 12 / kg; the specification is 3000 silver carp of 3 to 4 / kg; the specification is 10000 grass carp of 6 to 8 / kg; 1,000 herrings with 3-4 / kg; 8,000 crucian carp with 15-18 / kg. The snails were put in after clearing the pond a year ago, and the amount of snails put in was 500 kg. The above fish species are stocked before spring.

[0091] The feeding...

Abstract

The invention discloses an ecological fish culture and biological water purification integrated breeding system and an ecological fish culture and biological water purification integrated breeding method, and solves the problems that feed is utilized incompletely, water eutrophication is aggravated, the fish products have low quality and the like in the conventional fish culture in running water. The breeding system mainly comprises a running water pool (1) with a water inlet (2) and a water outlet (3) and is characterized in that an interception device (4) for intercepting plankton is arranged at the water outlet (3) in the running water pool (1). The invention also relates to the ecological fish culture and biological water purification integrated breeding method. In the system and the method, the feed can be utilized completely and the aim of feeding little bait or no bait and not applying fertilizer is fulfilled. The system and the method have the advantages of ecological fish culture and biological water purification.

Description

technical field [0001] The invention relates to a breeding pond, specifically a breeding system integrating ecological fish farming and biological water purification; the invention also relates to a breeding method. Background technique [0002] Dahe ecological fish has a wide variety, good taste and rich nutrition, and the market demand exceeds supply; now ecological fish has become a high-end healthy delicacy pursued by fashionable cities. According to the market price, this problem can be better explained. For example, the price difference of catfish is doubled, the difference of Huanglatin and Qingbo fish is 2-3 times, the difference of Jiangtuan is 3-5 times, the difference of soft-shelled turtle is 6-8 times, rare species such as mullet, The price of Iwahara carp reaches 300-400 yuan per kilogram. The price of ecological fish has remained high for a long time, and it has immeasurable development potential. The market's pursuit of big river fish clearly shows that ecol...
