How to cultivate sea cucumbers efficiently and in high yields?

The sea cucumber market has encountered unprecedented challenges, including the impact of market conditions, the impact of aquaculture production, and the impact of terminal market consumption. Finding a correct aquaculture idea in various difficult situations is something that every sea cucumber farmer must think about. How to efficiently and productively cultivate sea cucumbers? You need to pay attention to the specific conditions of the water, the temperature, the specific conditions of the water quality and salinity, and the surrounding environment for high temperature resistance, as well as the selection of varieties.

First, to cultivate sea cucumbers efficiently, you should pay attention to the temperature of the water; second, you should also pay attention to the entire operation process; third, you should get some medicine and powder, so that the sea cucumbers can grow well slowly.

The weather in northern China from July to mid-August this year was not good, with high temperatures and heavy rains lasting for several rounds. Although the losses were not as severe as in 2013, the current breeding situation cannot withstand any disturbances. During this period, sea cucumber farmers basically had to go to the bottom of the pond to observe the situation every day. The editor visited many farmers in Dalian, and they revealed a piece of news: "Sea cucumbers in the sea cucumber circle that were fed with bait during the spring have better resistance, and the phenomenon of floating cucumbers and desquamation of the bottom of the pond is less common."

1. Improve the quality of feeding bait

Adding microecological preparations to the feed is undoubtedly the best choice. The most direct and cost-effective way to improve the physical fitness of sea cucumbers is to let them eat directly. This practice can not only improve the water quality and bottom quality, but also allow sea cucumbers to go to the beach earlier, which can be said to kill two birds with one stone. When it comes to processing granular feed, the product that must be mentioned is Novijian Yijiduli, a lactic acid bacteria strain that greatly saves costs by fermenting itself. The fermented lactic acid bacteria are directly added to the feed, replacing the water that must be used in the old formula.

2. Strengthen daily monitoring and management

During the breeding period, attention should be paid to strengthening the monitoring of water quality, salinity, water temperature and the growth of sea cucumbers. Because the pool is surrounded by stone slopes, the water level drops rapidly during drainage, and the sea cucumbers that have not returned to the water in time and are exposed outside should be picked up in time. Summer is a season when the temperature and salinity of the pool water change greatly. It is necessary to strengthen the inspection of the pool. If the water temperature is too high, the water color is abnormal, and the salinity changes greatly after heavy rain, fresh seawater should be replaced immediately to create a good environmental condition for sea cucumbers. At the same time, pay attention to observe the activities and feeding conditions of sea cucumbers every day, and keep records. Go into the water every 15 days or so to explore and measure sea cucumbers. The embankment should be safe during the rainy season in summer.

3. Change water frequently

Change the water more often during high tide and less often during low tide. Change about 30% of the water each time during high tide and about 15% each time during low tide. Changing the water not only provides a large amount of high-quality natural bait for sea cucumbers, but also ensures the freshness and stability of the water quality.

4. Eliminate enemies

Eliminating pests in the early stage of stocking is an important part of sea cucumber farming. Use "ground traps" to trap crabs and fish, pick up starfish outside the pond and dry them, especially when changing water, to prevent crabs and fish from entering the sea cucumber pond.

5. Release local sea cucumber autumn seedlings

From the autumn seedlings bred locally, choose large seedlings (300-400 heads/kg). When choosing seedlings, pay attention to the following issues: The selected seedlings have no damage on the body surface, are clean, have no mucus, have intact, sharp, thin and tall thorns, naturally stretch their bodies, have strong vitality, and are sensitive to external stimuli. Put the seedlings in your hand and shake them back and forth a few times. The seedlings shrink quickly and have strong adhesion of the tube feet. When observed in the water, the feces discharged by the seedlings are in the shape of thick long strips. Select such healthy seedlings and release them all at once. The number of sea cucumbers per mu should be controlled at 4,000-4,500 heads.
