Farming sea cucumbers, do you know how to raise a good substrate after clearing the circle?

For sea cucumber farming, the quality of the substrate is one of the keys to breeding, the aging of some ginseng circles has seriously affected the benefits of sea cucumber breeding, the organic of the bottom of the pond has caused the flooding of aquatic weeds, the problem of hypoxia is difficult to solve, the poisoning of the bottom often occurs, and the skin of the drifting ginseng is very serious. Therefore, most farmers have begun to realize the importance of clearing the circle, but clearing the circle cannot solve all problems. How to do a good job in the management of the circle and the new circle is the key to the success of the follow-up breeding, here we give the following suggestions.

1. Clear the circle

1. Ploughing The aging of the bottom of the pond is not too serious, and the ginseng circle with little grass can choose to use a hook machine or a tiller used for planting to plough directly. It is best to drain the water before ploughing, and at the same time use 300 kg of quicklime for treatment. It can not only effectively sterilize and disinfect, but also improve the total alkalinity and redox potential of the bottom, enhance the overall buffering force of the pond, reduce water change and return to the bottom, and make sea cucumber cultivation more smooth.

2. Dredging Some of the ginseng circles are flooded because of the perennial water ingress and the accumulation of mud and sand, resulting in the inundation of the reef, and the sea cucumbers have no habitat, so mud pumps can be used for dredging. However, the pond is seriously aged or has a lot of grass, and the bottom environment is seriously damaged, and the pond must be backfilled with new soil after the overall dredging. The bottom of such a pond is very hard after dredging, so it is necessary to channel a few more times of water (preferably muddy water), and when a small amount of soil accumulates at the bottom, use "clear pond repair" for disinfection.

Remind everyone: after clearing the circle, we must do a good job of leveling the bottom of the circle, the small pit is easy to accumulate pollution, which will cause serious damage to the stocking ginseng seedlings.

2. Water conservation

1. Detoxification The use of multiple organic acids can reduce the impact of toxic and harmful substances on the survival rate of ginseng seedlings, and also provide a good breeding environment for bacteria and algae.

2. Replenishment of bacteria and carbon: In order to make the pond quickly restore biodiversity, stabilize the water body, and reduce the loss of ginseng seedlings caused by water change, "stable water + more beneficial bacteria" can be used to supplement bacteria and carbon, and the effect is outstanding.

3. Release seedlings

1. Hand picking up seedlings: After using anti-stress drugs two hours before the seedlings, put them directly on the reef or cage.

2. Shed seedlings: the pond with the cage is best to be temporarily raised in the cage for 3 5 days, and if the state is not good in the process of slowing down the seedlings, it can be continuously sprinkled with "activation + nutrition express" in the cage to help the adaptation and recovery of the seedlings and improve the survival rate of the seedlings.

Fourth, post-release management

1. Supplement exogenous bait: because there is not much natural bait at the bottom after the circle is cleared, it is necessary to supplement the exogenous "more seedlings" after the seedlings are released. It can not only provide the bait needed for ginseng seedlings to eat, but also play a role in supplementing bacteria.

2. Fertilizer and water: After the seedlings are released, because everyone is afraid that the ginseng seedlings will be stressed for more than ten days, it is necessary to make the pond water stable and properly fertilized. While making the pond environment good, it also supplements the natural bait for sea cucumbers.

Finally, according to the statistics of the overall pond clearance in 2017, 60% of the ponds have peeling, of which 20% are serious, and the remaining 40% may not have found problems due to careful observation. So we don't have any luck mentality, do a good job in the management of every detail of the new clearance, and lay a good foundation for our new beginning.

This is actually a bit rare, and there are a lot of steps, which is really troublesome.

Ring clearance is a very critical part. The long-term breeding and aging of sea cucumber circles will lead to the flooding of aquatic weeds and lack of oxygen, which will seriously affect the growth of sea cucumbers and lead to their death.

Appropriate supplementation of strains can be made, and organic acids should also be used appropriately. It is necessary to ensure the stability of the water body, and anti-stress drugs should also be used.

The pond where sea cucumbers are cultivated may become turbid in autumn, so it is important to improve the pond in time.

Common problems are actually prone to some diseases, such as parasites, like this ** ulceration problem, generally speaking, you need to pay attention to this water quality, timely bacterial disinfection and debris cleaning can be effectively avoided.

If the water quality is poor and there are many enemies, it is necessary to change the water frequently, remove the bottom algae frequently, and add various vitamins.

How can the sea cucumber circle clear the pond so that it can no longer reproduce. Is that so?

1.It is best to prevent the steel wire grass, in the case of no grass and not many protozoa and algae seeds, you can first use the blue water safety pool to splash, soak the tricyclic vitality source and oligosaccharides together for two hours, and sprinkle the whole pool with diatom Wang.

2.When the steel wire grass is already difficult to control, the method of manual removal can be adopted, but it is necessary to try to avoid making the grass boiling when it is manually fished, because the steel wire grass is rootless and reproduces, and a section can soon grow into a piece. It is best to do manual removal below the water temperature of 18 to 20 degrees.

3.Immediately after fishing, use 150-200 grams of promethonyl mu. It can inhibit their growth for a long time. But dead grass must also be removed, especially during periods of heat. Try not to use herbicidal herbs at high temperatures to avoid rotting and deterioration of dead grass at the bottom of the pond, so that sea cucumbers are poisoned and die!

4.It is necessary to strengthen daily management, raise the water level in the pool as much as possible, reduce transparency and avoid strong sunlight! Change the water frequently, especially if the water temperature exceeds 20 degrees.
