Problems solved by technology

Even if the output of crayfish with high density is lower and the density is higher, the breeding efficiency is still low
However, the similar prior art eel rice breeding mode left the paddy field breeding ditches before July idle, and the breeding benefits were not maximized.

Embodiment 1

[0023] A kind of comprehensive planting and raising method of eel, shrimp and rice provided by the present embodiment, taking the Jianghan Plain area as an example, carries out according to the following steps:

[0024] 1. Production and installation of eel hatching equipment

[0025] The transformation of eel, shrimp and rice integrated rice fields is the same as that of shrimp and rice co-cultured rice fields. It is carried out in winter, with 4m wide and 1.5m deep breeding ditches excavated, rice fields leveled, and supporting water inlet and drainage facilities constructed. Before the seedlings of crayfish are released at the end of March, each mu (667m 2 ) Paddy fields are thoroughly disinfected by splashing 75-100kg of quicklime to remove wild fish such as eels and loaches stored in the rice fields.

[0026] 2. Crayfish farming

[0027] At the end of March and the beginning of April, when the water temperature reached above 18 degrees, seedlings of crayfish were put in...

Embodiment 2

[0037] A kind of comprehensive planting and raising method of eel, shrimp and rice provided by the present embodiment, taking the Jianghan Plain area as an example, carries out according to the following steps:

[0038] 1. The production and installation of the eel hatching equipment are the same as in Example 1.

[0039] 2. Crayfish farming

[0040] At the end of March and the beginning of April, when the water temperature reached above 18 degrees, the seedlings of crayfish began to be put in, and about 5,000 crayfish seedlings weighing 4g were put in per mu of paddy fields. Breeding and management are carried out in accordance with the shrimp-rice co-cultivation regulations. The fishing starts in mid-May, and the big ones are kept small. When the water temperature reaches above 28°C in late June, the crayfish begin to live in caves and make holes, and almost no shrimps get into the shrimp cages. stop fishing.

Embodiment 3

[0050] A kind of comprehensive planting and raising method of eel, shrimp and rice provided by the present embodiment, taking the Jianghan Plain area as an example, carries out according to the following steps:

[0051] 1. The production and installation of the eel hatching equipment are the same as in Example 1.

[0052] 2. Crayfish farming

[0053] At the end of March and the beginning of April, when the water temperature reached above 18 degrees, seedlings of crayfish were put in, and about 4,000 seedlings of crayfish weighing 6g were put in per mu of paddy field. Breeding and management are carried out in accordance with the shrimp-rice co-cultivation regulations. The fishing starts in mid-May, and the big ones are kept small. When the water temperature reaches above 28°C in late June, the crayfish begin to live in caves and make holes, and almost no shrimps get into the shrimp cages. stop fishing.

Abstract

The invention provides a comprehensive planting and breeding method of eels, chicken lobsters and rice. The method includes the steps: selecting and reconstructing a breeding rice field; chicken lobster breeding: releasing young chicken lobsters after water temperature reaches 18 DEG C or more at the end of March to the beginning of April, catching large chicken lobsters in the middle of May, remaining small chicken lobsters in the rice field, and stopping catching of the chicken lobsters when the water temperature reaches 28 DEG C or more in the middle ten days and the last ten days of June;transplanting rice seedlings on the rice field after water levels of peripheral ditches of the rice field are lower than a plane of the rice field when water in the rice field is drained; eel breeding: erecting eel breeding net cages on the peripheral ditches of the rice field before the middle of June, releasing young eels on sunny days of the early ten days and the last ten days of July to culture the eels, catching the eels on the middle ten days and the last ten days of October, and disassembling the breeding net cages; young chicken lobster density controlling by the eels: releasing the eels into the peripheral ditches of the rice field on the middle ten days and the last ten days of October every year, catching the chicken lobsters in chicken lobster cages in May next year, and completely catching the eels in the rice field in late June when breeding of the chicken lobsters is completed. According to the method, the eels, the chicken lobsters and the rice are comprehensively planted and bred, and breeding in the rice field can be implemented all year round.

Description

technical field [0001] The invention relates to the technical field of fishery science application, in particular to a method for comprehensive breeding of eel, shrimp and rice. Background technique [0002] At present, the comprehensive cultivation of shrimp and rice is one of the effective methods to improve the comprehensive benefits of paddy fields, but this model does not give full play to the benefits of paddy fields, and its main shortcomings are: [0003] (1) The suitable growth temperature for crayfish is 18°C ​​to 28°C, and the optimum growth temperature is 23°C to 27°C. If it is higher than 28°C or lower than 18°C, it will live in caves and stop growing. Therefore, the growth time of crayfish in the rice fields of the middle and lower reaches of the Yangtze River in my country's main breeding areas is only from March to June every year. After July, due to the high temperature, crayfish will hibernate, and their breeding time in rice fields is only about 4 months a...
