Do you know several important factors that affect the growth of sea cucumber in autumn?

1. The physical problems of sea cucumber are affected by the hot weather this summer. The sea cucumber has some problems, such as coming out of the reef late, landing slowly, eating less, having fine feces and being stiff. The poor constitution of sea cucumber has become the main problem affecting its growth.

The main reasons are: sea cucumber is weak in constitution and poor in activity ability, and only likes to move near rocks, rather than going to the seaside. The intestinal recovery of sea cucumber is slow, and the length of intestinal recovery of sea cucumber is only 2 times of body length, while it can reach 3-4 times in the same period last year. Affected by their own constitution and intestinal digestion and absorption, sea cucumbers eat less, their intestines are not open, they are fine dung-like, and their bodies are stiff.

Suggested treatment plan: during the autumn feeding period of sea cucumber, the "oligosaccharide 863+ aquatic food-attracting yeast" should be sprinkled once every half month to enhance the constitution of sea cucumber, improve its own immunity, promote the reproduction of intestinal beneficial bacteria and promote the feeding growth.

2. Water quality environment and sediment environment: With the decrease of temperature this year, the transparency of water body is still very poor, so most farmers choose artificial clean water, and most of them choose pesticides such as triadimefon, trichlorfon and snail control, which is very harmful to water quality and sediment. In addition, the feeding of bait and the excretion of sea cucumber increase the burden on the bottom of the pond, which leads to the aggravation of pond pollution and the decrease of purification ability. Good water quality and sediment are the growth of sea cucumber.

Suggested treatment plan: use "Didujing (chlorine dioxide effervescent tablets)+Shuangdi 'an" water to improve the bottom and increase the transparency of the pond. Regularly use "ground improvement+(enhanced psychrophilic) probiotics" to supplement beneficial bacteria, decompose feces, feces and other organic substances in the residual bait in the pond, and increase the water purification ability. Using "low-temperature diatom auxin" to directionally cultivate diatoms can stabilize the water environment, increase the natural bait of sea cucumber and improve the productivity of ponds.

Third, the external weather changes and bait supply: if the temperature drops rapidly, the natural bait decreases, and the sea cucumber is affected by factors such as stress and lack of materials, the feeding period on the beach is short, and most of them wander around the reef. The change of weather and lack of bait seriously affect the growth of sea cucumber.

Suggested treatment scheme: with the decrease of temperature, appropriately raise the water level, increase the buffering capacity of water body, and reduce the influence of stress factors. Replenish fermented bait in time to increase the lure of bait. In the pond with rich bait, sea cucumber has good ingestion, good physique and strong anti-stress ability.
