Problems solved by technology

However, this method cannot control the temperature of the growth environment of Portunus trituberculatus. The growth and spawning of Portunus trituberculatus are easily affected by the weather temperature. At the same time, the spawning period of Portunus trituberculatus is not uniform, and the demand for labor costs is large.

Embodiment 1

[0046] A kind of portunus trituberculatus cultivation method comprises the following steps:

[0047] S1: preset pool water temperature and heating time;

[0048] S2: Divide the heating time into several time nodes, and divide the water temperature into several sequentially increasing temperature thresholds according to the preset pool water temperature and time nodes;

[0049] S3: Every time a node is reached, the temperature of the pool water is controlled to rise to the corresponding temperature threshold, and the temperature is maintained.

[0050]S4: Stop heating when the temperature rises to the preset water pool temperature and maintain the temperature.

[0051] By presetting the pool water temperature and heating time, the heating time is evenly divided into several nodes to achieve the effect of gradual heating, which is more in line with the development and spawning needs of oviposit crabs, and promotes oviposition crabs. When the water temperature rises to the prese...

Embodiment 2

[0054] like figure 2 and image 3 Shown, a kind of portunus trituberculatus culture control system, comprises

[0055] Timing module 3: output a timing signal at intervals, timing module 3 can adopt 555 timers, single-chip microcomputer 51 or 8253 timing chip to realize, and above-mentioned timer or timing chip are the timing chip of timing function commonly used in the prior art , which will not be described here.

[0056] Counting module 4: used for accumulatively counting the timing signal output by the timing module 3; the counting module 4 can use JDM11-5H, JX2836 and other types of counter chips.

[0057] Signal conversion module 5: convert the digital information after counting module 4 accumulative counting into analog voltage information signal as the reference voltage signal corresponding to each temperature threshold;

[0058] Temperature control module 6: controlled by the analog voltage signal to raise the water temperature to a corresponding temperature thres...

Abstract

Provided is an ecological seedling breeding method for portunus trituberculatus. The method includes the following steps of S1, presetting pool water temperature and temperature rise time; S2, dividing the temperature rise time into several time nodes, and dividing water temperature into several temperature threshold values increased in sequence according to the pool water temperature and the timenodes; S3, controlling the pool water temperature to rise to the corresponding temperature threshold value every time a time node is reached, and maintaining the temperature; S4, stopping heating andmaintaining the temperature when the temperature rises to the preset pool temperature. The method can intelligently control the environment in a breeding pool for the portunus trituberculatus, and anenvironment which is more suitable for growth and propagation requirements of the portunus trituberculatus is provided for the portunus trituberculatus, so that the spawning rate of the portunus trituberculatus is improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a breeding method and control system for portunus trituberculatus. Background technique [0002] Portunus trituberculatus is an important economic crab species along the coast of China. Portunus generally live and reproduce at a depth of 3-5 meters, and migrate to a depth of 10-30 meters in winter, preferring to live in caves at the bottom of the sand. Its suitable salinity is 16-35, the water temperature is 4°C-34°C, the pH value is between 7-9, the optimum salinity is between 26-32, and the optimum temperature is 22°C-28°C. Portunus trituberculatus grows rapidly and is highly profitable to breed. It has become an important cultured species in coastal areas of China. [0003] For example, the Chinese patent whose notification number is CN102356759A discloses a three-dimensional pond culture method for Portunus trituberculatus. By partially laying a fine sand layer with a th...
