Treatment Scheme of Pond Bottom in Small Shed Culture

Time:2023Year10Month

Time: Dongying, Shandong

Breeding species: Penaeus vannamei

small shed area and stocking specifications:40mu of land water depth1m; stocking specifications are57000/Shed

1.Cause of Problem

After the spring stubble shrimp farming and sales, the time base for clearing the pond and basking the pond is very short, so most of the small shed halls are directly put into water for farming after a short and simple treatment. As a result, the organic matter produced by the previous crop accumulated in a large amount at the bottom of the shed and could not be decomposed and oxidized in time.

2.Problems appear:

（1) The silt at the bottom of the pond contains a large number of pathogenic organisms, and the immune system of the shrimp seedlings released in the early stage is not perfect, which is extremely easy to infect and die of pathogens.

（22) A large amount of organic matter at the bottom of the pond is decomposed without oxygen during the high temperature period, resulting in a large amount of harmful substances such as ammonia nitrogen, sub-salt, hydrogen sulfide, etc., resulting in the death of shrimp seedling poisoning.

（31) The rich nutrition in the early stage of cultivation leads to excessive concentration of water body, easy to appear phenomena such as algae inversion, and great changes in water quality, resulting in stress.

3.Solution measures:

In the early stage of breeding, it is necessary to increase the intensity of bottom modification to prevent the index from exceeding the standard and eliminate harmful bacteria. It is recommended to use strong oxidation type bottom modification.

This product can be directly sprinkled evenly, the dosage is4~6When the situation is serious, increase the dosage appropriately. Super bottom change with clear water detoxification Ann use effect is better.

The next day after the bottom is changed, dilute with water and spill the whole pool. Pond: used for water transfer, per mu. rice dosage100-125ml(per bottle5LDosage40-50Mu), if serious, add the amount as appropriate; When used as detoxification, each mu. rice dosage200-250ml(per bottle5LDosage20-30Mu), can be used continuously when poisoning is serious.2-3Times.

5.Summary

Aquaculture water quality is one of the important factors to determine the success or failure of aquaculture, as the saying goes“Aquaculture raises water first, and raises water by changing the bottom.”The bottom quality is good, the water quality is naturally good. Bad environment is the main factor of aquaculture, so the quality of the bottom is related to the success of aquaculture.
