CREAT A NEW ERA OF CAGE CULTURE
Product Introduction
Cage Culture is themain way of mariculture,there are broad prospects for development.Since 1990s,with the rapid development of ocean cage culture in china, it has brought remarkable social and economic benefits. Thetraditionalcagewithsimplestructure,aremainlyprocessedbywoodboard,steelpipeorothermaterials, has weak anti wind and wave resistance capability, small scale, short service life etc.The setup sea area of traditional cage islimited,onlyintheinner bay and near shore,and cause high culture densities,pollution, disease andotherproblemsareimpactincreasinglyseriousinlocalmarinearea,thedevelopment of mariculturehasbeenseriouslyaffected.
The ocean cage culture system of China LESsO was launched in this context, LESsO ocean cage culture is used high strenghth HDPE pipe to replace traditional cage materials, its characteristics are main components of systemas standare products,strongplasticity,easy installation,convenient movement,environmental-friendly and durable. Compare as tranditional cage system, LESsO ocean cage system is significantly improved in anti-wind,waveresistance,flow resistance and other comprehensiveperformance.
ADVANTAGEOF LESSO OCEAN CAGE CULTURE SYSTEM
High Economic Benefit
In large volume, high yield, suitable for large-scale prodution and operation of enterprise. Away from the bay and land, excellent water and environment, high survival rate, fast growth, highqualitymarineproducts.
Strong Anti-Wind Capability. High Cold Resistance. Long Service Life
LESSO ocean cage culture is used high density and high toughness HDPE material, which can anti force 12 typhoon, and withstand -50°\mathsf{C} water temperature, Its service life is up to15 years andsuitfordeepseamariculture.
Environment Friendly, No Pollution
LESSO ocean cage culture is used HDPE material,which has no pollution and strong corrosion resistance.
Expand The Ocean Space
Because theHDPEmaterial of oceancage culturewith characteristicsof strongwaveresistance and long service life, therefore it's suitable for away from the land-based pollution deep sea mariculture,greatlytransferthebreedingpressureofthebay,andexpand themariculturearea.
Strong Defensive
LESSO ocean cage culture is used the safety fence for protection, and can adjust the droop depth of the fishing net.
