Problems solved by technology

[0002] At present, the success rate of raising Penaeus white shrimp is low, and sometimes the mortality rate of shrimp reaches 80 to 90%. Depending on luck, the price of shrimp is high, but the water pollution is serious and it is difficult to breed successfully, so it is difficult for most farmers to make money. There is a price but no shrimp
At the same time, a large number of drugs make the quality of shrimp poor, most of them are unhealthy and unsafe, and more drugs will further pollute the water body, such a vicious circle
As for tilapia farming, due to the high rent of fish ponds and the sharp increase in the price of feed, the price of fish has not increased much, so the efficiency of farming is also very low.

Embodiment 1

[0017] A kind of cultural method of raising white prawns with tilapia cover, is characterized in that, comprises the steps:

[0018] (1) Pond treatment: first drain the pond water, use 100kg / mu of quicklime to sterilize, and then sun-dry the pond for 5 days, inject water to a depth of 80cm 10 days before stocking, filter the water with a 60-mesh silk screen, and then use bleaching powder after entering the water Disinfect the water once at 1 mg / L; after 3 days of pool water disinfection, use inorganic fertilizers to cultivate the plankton in the water, so that the water color in the pool is yellow-green or dark green, and the transparency is about 30cm, and the salinity of the culture pool water is kept at 1.5;

[0019] (2) Seed stocking: stocking of Penaeus vannamei seedlings in mid-April with a stocking density of 20,000 fish / mu and a body length of 1 cm; stocking tilapia fingerlings in late April with a stocking density of 1,500 fish / mu Mu, with an average body length of 4c...

Embodiment 2

[0025] A kind of cultural method of raising white prawns with tilapia cover, is characterized in that, comprises the steps:

[0026] (1) Pond treatment: first drain the pond water, use 100kg / mu of quicklime to sterilize, and then sun-dry the pond for 7 days, inject water to a depth of 80cm 10 days before stocking, filter with 60-mesh silk screen when entering the water, and then use bleaching powder after entering the water Disinfect the water once at 1 mg / L; after 3 days of pool water disinfection, use inorganic fertilizers to cultivate the plankton in the water, so that the water color in the pool is yellow-green or dark green, and the transparency is about 30cm, and the salinity of the culture pool water is kept at 3.0;

[0027] (2) Seed stocking: Stocking Penaeus vannamei seedlings in mid-April, the stocking density is 20,000 fish / mu, and the body length of shrimp seedlings is 2cm; stocking tilapia fingerlings in late April, the stocking density is 1,500 fish / mu Mu, with a...

Embodiment 3

[0033] A kind of cultural method of raising white prawns with tilapia cover, is characterized in that, comprises the steps:

[0034] (1) Pond treatment: first drain the pond water, use 100kg / mu of quicklime to sterilize, and then sun-dry the pond for 6 days, inject water to a depth of 80cm 10 days before stocking, filter the water with a 60-mesh silk screen, and then use bleaching powder after entering the water Disinfect the water once at 1 mg / L; after 3 days of pool water disinfection, use inorganic fertilizers to cultivate plankton in the water, so that the water color in the pool is yellow-green or dark green, and the transparency is about 30cm, and the salinity of the culture pool water is kept at 2.0;

[0035] (2) Seed stocking: Stocking Penaeus vannamei seedlings in mid-April, the stocking density is 20,000 fish / mu, and the body length of shrimp seedlings is 2cm; stocking tilapia fingerlings in late April, the stocking density is 1,500 fish / mu Mu, with an average body l...

Abstract

The invention relates to the technical field of aquaculture, and concretely relates to an intercultivation method for oreochromis mossambicus and white prawns. The method comprises the following steps: (1) pond treatment; (2) fry throwing and culturing; (3) cultivation management; and (4) water quality management. The invention aims to provide the intercultivation method for the oreochromis mossambicus and the white prawns, white prawn intercultivation in an oreochromis mossambicus pond can fully utilize cultivation water space, reduce prawn cultivation costs, effectively control prawn diseases and infection, and improve cultivation economic benefits.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating white prawns in sets of tilapias. Background technique [0002] At present, the success rate of raising Penaeus white shrimp is low, and sometimes the mortality rate of shrimp reaches 80 to 90%. Depending on luck, the price of shrimp is high, but the water pollution is serious and it is difficult to breed successfully, so it is difficult for most farmers to make money, and there is a price but no shrimp.
