Problems solved by technology

[0002] In recent years, freshwater lobster has not only become an important freshwater aquatic product exported to Europe and the United States in large quantities, but also a delicacy on the tables of urban and rural residents in my country. The lobsters with slow growth rate are easy to become the food of larger lobsters, leading to cannibalism. The above-mentioned breeding technology cannot protect smaller lobsters, resulting in a decrease in survival rate. High, fast infection, making the quality of lobster not high

Embodiment 1

[0029] Such as figure 1 Shown, freshwater lobster benign ecological breeding method comprises the steps:

[0030] Step 1: Select a breeding pond with sufficient water source and long sunlight time;

[0031] Step 2: Rebuild the aquaculture pond, drain the pond water, remove the silt until the hard mud layer 4, form a 45° slope on both sides of the pond, after disinfection and exposure in the pond, lay a gravel layer 3 on the hard mud layer 4, and lay the gravel layer 3 on the hard mud layer 4 Fixing the juvenile shrimp protection layer 1, the juvenile shrimp protection layer 1 is formed with a through hole 2 that only allows the juvenile shrimp to pass through, and the juvenile shrimp protection layer 1 is covered with a mud layer;

[0032] Step 3: Cultivate aquatic plants. Select the water source in the breeding pond before sunrise in late spring. The depth of the water body is 2 / 3 of the depth of the pond. At the bottom of the pond, cultivate 1 / 4 of the bottom area of ​​subm...

Embodiment 2

[0048] Such as figure 1 Shown, freshwater lobster benign ecological breeding method comprises the steps:

[0049] Step 1: Select a breeding pond with sufficient water source and long sunlight time;

After disinfection and exposure in the pond, lay the gravel layer 3 on the hard mud layer 4, and lay the gravel layer 3 on the hard mud layer 4 Fixing the juvenile shrimp protection layer 1, the juvenile shrimp protection layer 1 is formed with a through hole 2 that only allows the juvenile shrimp to pass through, and the juvenile shrimp protection layer 1 is covered with a mud layer;

[0051] Step 3: Cultivate aquatic plants. Select the water source in the breeding pond before sunrise in late spring. The depth of the water body is 2 / 3 of the depth of the pond. At the bottom of the pond, cultivate 1 / 4 of the bottom area of ...

Embodiment 3

[0067] Such as figure 1 Shown, freshwater lobster benign ecological breeding method is characterized in that: comprises the steps:

[0068] Step 1: Select a breeding pond with sufficient water source and long sunlight time;

[0069] Step 2: Rebuild the aquaculture pond, drain the pond water, remove the silt until the hard mud layer 4, form a 50° slope on both sides of the pond, after disinfection and exposure in the pond, lay a gravel layer 3 on the hard mud layer 4, and lay the gravel layer 3 on the hard mud layer 4 Fixing the juvenile shrimp protection layer 1, the juvenile shrimp protection layer 1 is formed with a through hole 2 that only allows the juvenile shrimp to pass through, and the juvenile shrimp protection layer 1 is covered with a mud layer;

[0070] Step 3: Cultivate aquatic plants. Select the water source in the breeding pond before sunrise in late spring. The depth of the water body is 2 / 3 of the depth of the pond. At the bottom of the pond, cultivate 1 / 4 of...

Abstract

A fresh-water benign ecologic lobster breeding method comprises the following steps of address selection of a breeding pond, reconstruction of the breeding pond, cultivation of aquatic plants, puttingof fresh-water herbivorous trash fish, larva putting and feed putting. The fresh-water benign ecological lobster breeding method has the advantages that smaller-sized lobsters can hide in through holes and are prevented from being cannibalized by larger-sized lobsters by the arrangement of a larva protecting layer at the bottom of the pond, and the survival rate of the lobsters is improved; plants and trash fish are bred in a water body, the pond can be attractive, travel, shrimp fishing and other agritainment activities can be facilitated, the water quality can be kept through trash fish breeding, sufficient live bait is provided for the lobsters, and the quality of the lobsters is improved; an ecologic breeding environment cooperates with a breeding management method, the survival rateof the lobsters is improved remarkably, the lobsters are larger and have better meat, and the incomings of farmers are increased.

Description

Technical field: [0001] The invention relates to the field of ecological aquaculture, in particular to a method for benign ecological cultivation of freshwater lobsters. Background technique: [0002] In recent years, freshwater lobster has not only become an important freshwater aquatic product exported to Europe and the United States in large quantities, but also a delicacy on the tables of urban and rural residents in my country. The lobsters with slow growth rate are easy to become the food of larger lobsters, leading to cannibalism. The above-mentioned breeding technology cannot protect smaller lobsters, resulting in a decrease in survival rate. High, fast infection, making the quality of lobster is not high. Invention content: [0003] The object of the present invention is to provide a freshwater lobster benign ecological breeding method in order to solve the existing problems. [0004] Technical solutions of the present invention are as follows: [0005] A freshwa...
