Daily Management of Cultured Sea Cucumber

Sea cucumber was originally called Sha Li, because it is covered with flesh thorns, looks like a cucumber, and is also known as "sea cucumber". Its nutritional value is very high. As a valuable tonic to prolong life, it is known as ginseng in the sea, so it is named sea cucumber. According to expert analysis, sea cucumber is mainly composed of a large number of mucin and a variety of amino acids, with anti-tumor, anti-coagulation, anti-aging effect.

1. Pond conditions

Sea cucumbers generally live in the shallow waters of 3m-15m and like to live on the bottom of rocks where the current is calm and seaweed is luxuriant or where there is a clump of leafy algae and hard sand. It is not tolerant to low salt, and the most suitable salinity is 28-38, so the pond should be built in a wide sea area, clear water quality, rich bait, far from the estuary and no pollution, in which sea cucumbers grow faster.

Sea cucumbers like to attach to hard attachments, so breeding sea cucumbers should specially create such an environment for them to build artificial reefs by throwing stones, tiles and cement bricks at the bottom of the pond. Because the surface area of stone is relatively large, and there are many basic baits for growth, it can be used to feed sea cucumbers, so the effect of building reefs with stones is the best.

After the pond is built, the ginseng seedlings are released. Seedling selection should pay attention to early, large, and strong, that is, the first batch of eggs laid are more robust, so we should choose early seedlings; if the seedlings are more abundant, we should choose large seedlings as far as possible; among the same batch of large seedlings, if they are all very large, we should choose strong seedlings. It should be noted that the stocking density should be reasonable, and excessive stocking density will cause diseases.

2. Seedling selection

Select the seedlings with 3cm-10cm specification and no injury and disease, stocking 2000-6000 head per 1 hectare. Too high stocking density may cause disease or even not grow up, resulting in low commodity rate.

3. Culture management

The daily management of sea cucumbers is simple. One is to change water and adopt free tide-bearing aquaculture, which should be guaranteed to take in water twice a day. A small amount of water exchange is prone to diseases.

Sea cucumbers have strong adaptability to temperature and can grow normally in the water temperature range of 0 ℃-20 ℃. But when the temperature exceeds 28 ℃, it is necessary to take measures such as shading and changing water to cool down. At ordinary times, the feeding and management of sea cucumbers is relatively simple, sea cucumbers mainly feed on plankton, benthic diatoms and organic detritus, and the bait organisms in sea water can basically meet their growth needs, and an appropriate amount of feed can be fed in the season with few plankton.

The enemies of sea cucumbers are less, mainly Japanese Sturgeon and sea bass, which should be fished out in time as soon as they are found.
