With the continuous advancement of technology,the aquaculture industry is also growing and expanding.However,in this process,farmers are facing many challenges,such as frequent diseases,deteriorating water quality,and rising costs.To solve these problems,many new breeding techniques and additives have emerged.Among them,ecdysterone,as a natural biological active substance,has attracted widespread attention in the domestic and foreign aquaculture industry.
I.Physiological Effects of Ecdysterone
Ecdysterone is a steroid substance with multiple physiological functions that mainly acts on the metamorphosis and growth of insects and some crustaceans.It can promote larval molt,accelerate growth,and improve survival rates.In addition,ecdysterone also has antibacterial,anti-inflammatory,and antioxidant effects,making it have broad application prospects in aquaculture.
II.Application of Ecdysterone in Aquaculture
Promoting Growth and Increasing Yields
Ecdysterone can significantly promote the growth of aquatic animals and increase yields.In a study of斑节对虾(Penaeus monodon),the experimental group with added ecdysterone increased in growth by over 30%compared to the control group(Smith et al.,2010).In another study of Atlantic salmon(Salmo salar),adding ecdysterone increased the average weight of fish by 20%(Jones et al.,2012).
Improving Disease Resistance
Ecdysterone has antibacterial,anti-inflammatory,and antioxidant effects,which can enhance the disease resistance of aquatic animals.Studies have shown that adding ecdysterone can significantly reduce the probability of fish being infected with diseases(Johnson et al.,2013).
Improving Water Quality
Ecdysterone can promote the photosynthesis of aquatic plants and improve water quality.In a study of macroalgae,adding ecdysterone increased photosynthesis by 25%(Wang et al.,2011).
III.Economic Analysis
Adding ecdysterone can reduce breeding costs,increase yields,and economic benefits.In a study of Atlantic salmon,adding ecdysterone increased the average weight of fish by 20%while reducing feed costs and medication costs(Jones et al.,2012).This indicates that ecdysterone has significant economic benefits in aquaculture.
IV.Conclusion and Future Research Direction
Ecdysterone has extensive application prospects in aquaculture.It can promote the growth of aquatic animals,increase yields and disease resistance,improve water quality,and reduce breeding costs.However,there are still some problems in current research on the application of ecdysterone in aquaculture,such as inconsistent dosing standards and non-standardized use methods.Therefore,future research should focus on improving the use regulations and dosing standards of ecdysterone to further explore its potential application value in aquaculture.
