Sea cucumber daily management breeding technology
The original name of sea cucumber was Shali, because it was covered with a sting and looked like cucumber, and it was also known as the "sea cucumber." Its nutritional value is extremely high. As a valuable nutritional supplement for longevity, it has been hailed as a ginseng in the sea and is named after the sea cucumber. According to expert analysis, sea cucumbers are mainly composed of a large number of mucins and various amino acids, which have anti-tumor, anti-coagulation and anti-aging effects. 1. Pond conditions Sea cucumbers generally inhabit in a shallow sea of ​​3m-15m in size, and prefer to live in the calm waters, algae-rich rocky seabed, or hardwood sediments and hard sand. It is not tolerant of low salt. The most suitable salinity is 28-38. Therefore, the pond should be built in a wide sea area, clear water quality, rich bait, away from the estuary and no pollution of the sea area. Under such circumstances, the sea cucumber grows faster. Sea cucumbers like to be attached to hard attachments. The cultivation of sea cucumbers is intended to create a special environment for it. Artificial reefs are made by depositing stones, tiles, and cement bricks at the bottom of the pond. Because the surface area of ​​the stone is relatively large, there are also many basic bait that can be used to feed the sea cucumber. Therefore, the effect of stone-building reefs is best. 2, seed selection The size of seedlings with a size of 3cm to 10cm and no injuries was selected, and stocks of 2,000 to 6,000 heads per 1/15 ha were stocked. A large stocking density may lead to disease or even growth, resulting in a low commodity rate. 3, aquaculture management The daily management of sea cucumbers is simple. The first is to change the water and adopt free-nano-tidal culture. It is necessary to ensure that water is used twice a day. Changing the amount of water is less likely to cause disease. Sea cucumbers are highly adaptable to temperature and can grow normally within a temperature range of 0°C to 20°C. However, when the temperature exceeds 28°C, measures such as shading and water change are required to cool down. The usual feeding and management are relatively simple. The sea cucumbers mainly feed on plankton, benthic diatoms, and organic debris. The food organisms in the sea water can basically meet their growth needs. They can be fed during the season where there are few plankton. The right amount of feed. Sea cucumbers have less predators, mainly Japanese squid and squid. Once discovered, they must be removed in time.

After the pond is built, stocking seedlings is stocked. Seed selection should pay attention to early, large and strong, that is, the eggs produced by the first batch are more robust, so we must choose early seedlings; if the seeds are relatively abundant, we must try to choose large seedlings; if they are all large, we must Choose strong seedlings. It should be noted that stocking densities should be reasonable and excessive stocking densities can cause disease.
