Embodiment 1

[0021] Embodiment one: a kind of tilapia fence overwintering species preservation method of the present invention adopts the following steps:

[0022] The pond area is 18 mu, the water depth is 2 meters, and the fence area is 1.4 mu (933m 2 ), the top of the fence is higher than the water surface, and the bottom fence reaches the bottom of the pool to cut off the water, and no light-transmitting plastic greenhouse is built. A feeding platform 2 is set near the outer pond 1 meter at the gate of the fence, and a 1.5kw impeller aerator 5 is installed in the fence. There is a well 7 near the pond near the fence, with a flow of about 50m 3 / h. The upper frame of the fence is fixed on the fixed piles 6 on both sides of the bank with steel wire ropes 9, and is higher than the water surface. The wooden stakes 4 are inserted into the bottom of the pond as support piles every 1 meter. On the support pile, the thickness of the cloth is 0.5mm, and the diameter of the seam under the fen...

Embodiment 2

[0023] Embodiment two: a kind of tilapia fence overwintering species preservation method of the present invention adopts the following steps:

[0024] The pond area is 20 mu, the water depth is 2 meters, and the fence area is 1.5 mu (1000m 2 ), without a shed. A 1 meter wide doorway is set near the feeding platform 2, and a 1.5kw impeller aerator 5 is installed in the column. Drill a well 7 near the pond near the fence, with a flow of about 40m 3 / h. The top of the fence is higher than the water surface, and the bottom of the fence is cut off from the water to the bottom of the pond. The upper rail of the fence is fixed on the fixed piles 6 on both sides of the bank with a steel wire rope 9. Use a layer of silicone cloth 8 to sew on the upper rail of the fence and the support pile 4, the thickness of the cloth is 0.6mm, and the diameter of the seam of the lower rail of the fence is 20cm. , the doorway 1 deep to the bottom, as a doorway where water and fish can come in and ...

Embodiment 3

[0025] Embodiment three: a kind of tilapia fence overwintering species preservation method of the present invention adopts the following steps:

[0026] The area of ​​the pond is 28 mu, the water depth is 2 meters, and the area of ​​the fence is 5 mu. A feeding platform 2 is set near the outer pond 1 meter at the gate of the fence, and a 1.5kw impeller aerator 5 is installed in the fence. Equipped with 50m 3 / h deep water well as warm water source 7. The upper frame of the fence is fixed on the fixed piles 6 on both sides of the bank with steel wire ropes 9, above the water surface, steel pipes 4 are inserted into the bottom of the pond as support piles every 0.8 meters, and two parallel layers of PVC waterproof canvas 8 are sewn on the upper rails and supports of the fence. On the pile, the thickness of the cloth is 0.8mm, and the diameter of the seam under the fence is 15cm. The pipe bag 3 is filled with fine sand as a sinker, and an outlet 1 with a width of 1.2 meters and...

Abstract

The invention relates to a method for conserving overwintering breeds by fencing tilapia, which is characterized by comprising the following steps that: a supporting warm water area is arranged near a pond or a reservoir region; a fence is arranged in the pond or a reservoir; a fence head line is fixed on fixing piles on two sides of a shore by use of a wire rope, and waterproof thermal insulation materials are sewn on the fence head line and support piles; pipe bags are sewn on a fence foot line and are filled with fine sand as sinkers; a doorway of the fence is provided with the doorway where water and fishes can freely go in and out; warm water is pumped in to raise temperature; the doorway of the fence is provided with a feed table so as to ensure that the tilapia is easy to find the doorway of the fence through food inducement; as the water temperature in the fence is higher than that of an outer pond, the tilapia automatically swims into the fence to overwinter safely; and an oxygen-increasing machine is arranged in a fence water area to supplement overwintering fingerlings with oxygen so as to prevent fish aggregation from causing oxygen deficiency. The method ensures that the water temperature is kept within a survival range for the safe overwintering of the tilapia through less energy consumption and light labor, thereby raising the survival rate of the tilapia and helping the tilapia to smoothly overwinter and conserve breeds.

Description

technical field [0001] The invention relates to a tilapia fence overwintering species preservation method, in particular to a tilapia fence overwintering species conservation technique, belonging to the technical field of aquaculture. Background technique [0002] Tilapia is one of the main farmed fishes in the world. It has the advantages of strong adaptability, wide feeding habits, less fish diseases, fast growth, high yield, tender meat, and delicious taste. It is an excellent product promoted by the United Nations Food and Agriculture Organization to the world. species, the breeding range covers 85 countries and regions, and it is also one of the important breeding species for my country's export to earn foreign exchange. With the improvement of the improved breeding system and the improvement of breeding and processing technology, tilapia farming has become a pillar industry of agriculture in southern my country, forming a relatively complete industrialized production pa...
