Embodiment 1

[0030] In 2008, it was implemented in the pond of Hangzhou Zhouhong Apiculture Co., Ltd. Xiasha Breeding Base.

[0031] The method for polyculture of soft-shelled soft-shelled turtle Japanese strain and Litopenaeus vannamei pond comprises the following steps:

[0032] 1) Choose a pond with a quiet environment, no pollution around, leeward to the sun, and sufficient water sources, with independent water intake and drainage systems, escape prevention facilities, feeding tables and oxygenation facilities; there are 8 ponds in total, with a total area of ​​28.64 mu, rectangular, all of which are Oriented from east to west, the bottom of the pond is flat, with less silt, the ratio of length to width is 2:1, the ratio of slope to pond is 1:2, and the average water depth is 1.5 meters.

[0033] 2) Disinfect pond clear pond, store water, cultivate basic bait; use fermented organic fertilizer 150kg / acre, and per acre, sprinkle photosynthetic bacteria, 1kg of EM original dew beneficial ...

Embodiment 2

[0039] In 2009, it was implemented in the pond of Xiaoshan Haitian Aquaculture Co., Ltd., Hangzhou, Zhejiang.

[0040] The method for polyculture of soft-shelled soft-shelled turtle Japanese strain and Litopenaeus vannamei pond comprises the following steps:

[0041] 1) Choose a pond with a quiet environment, no pollution around, leeward to the sun, and sufficient water sources, all with independent water intake and drainage systems, escape prevention facilities, feeding tables and oxygenation facilities; 2 ponds, each with an area of ​​6 mu, are rectangular and Orienting east-west, the bottom of the pond is flat, with little silt, the ratio of length to width is 2:1, the ratio of slope to pond is 1:3, and the average water depth is 1.5 meters.

[0042] 2) Disinfect, store water, and cultivate basic bait in ponds and clear ponds; 200 kg / mu of fermented organic fertilizer or biological fertilizer, and 1.5 kg of photosynthetic bacteria and EM original dew beneficial microbial pr...

Abstract

The invention discloses a pond polyculture method of Chinese fresh-water turtle Japanese strain and Litopenaeus vannamei Boone, which comprises the following steps: (1) selecting a pond which has a quiet environment, no pollution in the circumference, sunny exposure and adequate water source and is out of the wind; (2) clearing and disinfecting the pond, storing water and culturing basic bait; (3) putting young Litopenaeus vannamei Boone into the pond from April 20th to May 15th, feeding with artificially compounded shrimp bait, and carrying out water quality management; after 25-35 days of growth of the shrimps, migrating the Chinese fresh-water turtle Japanese strain into the pond for culturing, feeding artificially compounded turtle bait from the day after the turtles are put into the pond, and carrying out culture management work; and (4) shrimping the Litopenaeus vannamei Boone for sale successively in August, and catching the Chinese fresh-water turtle Japanese strain for sale from December to March in the next year. The invention saves energy, reduces the occurrence probability of shrimp diseases, solves the problems of high risk, low land use capability, high culture cost and the like in the current pond culture, effectively improves the qualities of the shrimps and the turtles, and improves the economic benefit of culture.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a pond polyculture method of a Japanese strain of soft-shelled turtle and Litopenaeus vannamei. Background technique [0002] In recent years, Litopenaeus vannamei has been rapidly developed as an excellent variety of marine shrimp in light culture in the country. However, with the continuous expansion of the breeding scale and the increasing degree of intensification, many problems have also appeared in the breeding production. First, the frequent occurrence of diseases, such as taola syndrome and white spot syndrome. The shrimp farming industry has brought significant economic losses; secondly, the serious degradation of germplasm, the single breeding mode and breeding species, etc., have caused the decline in the disease resistance of shrimp, the loss of control of the micro-ecological balance of the water environment, and the increased risk of farming, which seriously restricts Fan...
