Embodiment 1

[0017] Embodiment 1, a kind of mixed culture method of loach and vannamei, its steps are as follows:

[0018] (1) Pond conditions: choose a pond with an area of ​​4.5 mu as a breeding pond, with a silt depth of 10 cm, a pond ridge width of 1.4 meters, and a water depth of 0.8 meters; the inlet and outlet channels are separated, and polyethylene mesh is used to build a 1.15-meter-high anti-escape facility ;

[0019] (2) Seed stocking: In summer, loach seedlings and Penaeus vannamei seedlings are put into the pond synchronously. The size of Penaeus vannamei seedlings is 0.6 cm; For: Penaeus vannamei 25,000 tails / mu, loach seedlings 40,000 / mu;

[0020] (3) Breeding management: implement "four fixed" feeding, that is, timing, fixed point, qualitative and quantitative; feeding loach special feed four times a day, no longer feeding Penaeus vannamei feed alone, at 5:00 and 10:00 in the morning, Feed 30% of the total amount of the whole day; 2:00 p.m.

[0021] (4) Fishing of Penaeu...

Embodiment 2

[0023] Embodiment 2, a kind of mixed culture method of loach and vannamei, its steps are as follows:

[0024] (1) Pond conditions: choose a pond with an area of ​​5.5 mu as the breeding pond, with a silt depth of 20 cm, a pond ridge width of 1.6 meters, and a water depth of 1.0 meters; the inlet and outlet channels are separated, and polyethylene mesh is used to build a 1.30-meter-high anti-escape facility ;

[0025] (2) Seed stocking: In the summer, loach seedlings and Penaeus vannamei seedlings are put into the pond simultaneously. The size of the vannamei seedlings is 1 cm; the loach seedlings are overwintering seedlings, and the size is 300 tails / catties; For: vannamei seedlings 35,000 tails / mu, loach seedlings 60,000 tails / mu;

[0026] (3) Breeding management: implement "four fixed" feeding, that is, timing, fixed point, qualitative and quantitative; feeding loach special feed four times a day, no longer feeding Penaeus vannamei feed alone, at 7 o'clock in the morning, 12...

Embodiment 3

[0029] Embodiment 3, a kind of mixed culture method of loach and vannamei, its steps are as follows:

[0030] (1) Pond conditions: choose a pond with an area of ​​5 mu as a breeding pond, with a silt depth of 15 cm, a pond ridge width of 1.5 meters, and a water depth of 0.9 meters; the inlet and outlet channels are separated, and polyethylene mesh is used to build a 1.20-meter-high anti-escape facility ;

[0031] (2) Seed stocking: put loach seedlings and Penaeus vannamei seedlings into the pond synchronously in summer. The size of Penaeus vannamei seedlings is 0.8 cm; loach seedlings are overwintering seedlings, and the size is 200-250 tails / catties; The quantity is: vannamei 30,000 tails / mu, loach seedlings 50,000 / mu;

[0032] (3) Breeding management: implement "four fixed" feeding, that is, timing, fixed point, qualitative and quantitative; feeding loach special feed four times a day, no longer feeding Penaeus vannamei feed alone, at 6:00 am, 11:00 am, Feed 35% of the tota...

Abstract

The invention relates to a mixing breeding method for loaches and penaeus vannamei boone. The mixing breeding method comprises the following steps that a pond with the area ranging from 4.5 mu to 5.5 mu is selected as a breeding pond, the depth of sludge ranges from 10 cm to 20 cm, the bank width of the pond ranges from 1.4 m to 1.6 m, and the water depth is maintained to range from 0.8 m to 1 m; a water inlet channel and a water drainage channel are separated, and an escaping prevention facility with the height ranging from 1.15 m to 1.30 m is constructed with polyethylene meshes; in summer, loach fries and penaeus vannamei boone fries are synchronously put into the pond, wherein the put volumes are 25-35 thousands per mu for penaeus vannamei boone fries and 40-60 thousands per mu for loaches respectively fries; four-fixation, namely fixed time, fixed points, fixed quality and fixed quantity, feeding is conducted; the penaeus vannamei boone is captured after being bred for 50-65 days, and after the penaeus vannamei boone is completely captured, the loaches are successively captured after being continuously bred for 2-3 months. The mixing breeding method is reasonable in design, high in operability and obvious in breeding benefit. The ecological breeding mode of double-main-breeding of loaches and penaeus vannamei boone in the pond is achieved.

Description

technical field [0001] The invention relates to an aquatic culture method, in particular to a mixed culture method of loach and Penaeus vannamei. Background technique [0002] Loach is a common small special fish with wide distribution and large quantity. The largest individual is only about 80g. It is rich in nutrition, tender and soft, easy to digest and absorb, and has a unique flavor. High-grade economic fish is a high-grade aquatic nutrition product with high protein and low fat. Since the end of 2012, due to market factors, although the production of loach farming in some areas is high, the fish price is low and serious losses have occurred. Therefore, technical research on improving economic benefits by adjusting the structure of freshwater aquaculture has important social and economic benefits. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for mixing culture of loach and Penaeus vannamei wit...
