Ecdysterone is an active substance extracted from the roots of Cyanotis arachnoidea C.B.larke,a plant in the family Cyanoplantaceae.It is mainly involved in the molting process during the growth and development of insects and other arthropods.In recent years,with the in-depth study of ecdysterone,its application in aquaculture has been paid more and more attention.The potential and application of ecdysterone in aquaculture will be discussed in detail in this paper.
Potential of ecdysterone in aquaculture
1.Promote growth and development
Ecdysterone can affect the growth and development of aquatic animals and improve the efficiency of breeding.Studies have shown that the addition of ecdysterone can significantly improve the growth rate and individual size of aquatic animals.Ecdysterone may promote the growth and development of aquatic animals by affecting cell proliferation and differentiation.In addition,ecdysterone can also regulate energy metabolism,improve the energy reserve of aquatic animals,and further promote their growth and development.
2,improve disease resistance
Ecdysterone not only affects the growth and development of aquatic animals,but also enhances the function of the immune system and improves the resistance to disease.The immune system plays a key role in resisting the invasion of pathogenic microorganisms,and ecdysterone can stimulate the activation and proliferation of immune cells,improve antibody levels,and enhance immune defense.This helps to reduce the risk of disease in aquatic animals and reduce the cost of farming.
3.Optimize the breeding environment
Ecdysterone can affect the molting process of aquatic animals and help to optimize the breeding environment.For example,in the process of breeding,proper control of the secretion of ecdysterone can reduce the pollution of aquatic animals to water quality and sediment.Ecdysterone may regulate the physiological metabolism of aquatic animals and control their molting time,thus reducing the negative impact on the breeding environment.This method helps to reduce the deterioration of water quality,bottom pollution and other problems,and create a healthier growth environment for aquatic animals.
4,improve reproductive performance
Ecdysterone can also improve the reproductive performance of aquatic animals.In some aquatic animals,ecdysterone may be directly involved in the development of reproductive system and the regulation of reproductive behavior.Through rational use of ecdysterone,it can promote the gonad development and germ cell maturation of aquatic animals,improve their reproductive ability and reproductive efficiency.
Second,the application of ecdysterone in aquaculture
In actual production,ecdysterone is mainly applied in the following ways:
1,feed additives:The addition of molting hormone to feed is a common application.In this way,the growth rate and disease resistance of aquatic animals can be improved.The dosage and addition method of ecdysterone as a feed additive should be optimized according to the specific breed and water quality conditions to achieve the best results.
2,soaking:aquatic animals soaked in water containing molting hormone,can directly promote their growth and development and disease resistance.This method is suitable for some specific aquaculture varieties or specific growth stages of aquatic animals.During the soaking process,the concentration and soaking time of ecdysterone should be strictly controlled to avoid adverse effects on aquatic animals.
3,water quality improvers:The use of ecdysterone to optimize the breeding environment is another effective method.The addition of ecdysterone to aquaculture water can reduce the impact of aquatic animals on water quality.This is mainly achieved by regulating the physiological metabolism and molting behavior of aquatic animals.At the same time,ecdysterone can also promote the growth and reproduction of aquatic plants,and provide more high-quality natural food for aquatic animals.
To sum up,ecdysterone has great potential in aquaculture.Reasonable use of ecdysterone can significantly improve the growth rate,disease resistance and reproductive performance of aquatic animals,optimize the breeding environment and improve the breeding efficiency.
