Bacteria, fungus, virus and algae are the threat of aquatic animals. Reducing the probability of being invaded by the above factors equals to increasing safety and security of aquatic animals. In other words, reducing the risk of infection puts biosecurity of aquaculture into practice. Biosecurity is a sequence of effective management, each pool or tank is recorded and tracked in detail from source, daily feeding, and every move. We especially care about aquatic environmental hygiene, so we conduct the quarantine and health policy with help from national laboratory to eliminate specific key pathogen, or reduce the risk to reach safety standard. Different from manufacturing industry, our product is live aquatic animal. Recently we introduce ISO9001 into our production process, expecting to continuously fulfill global clients who require high quality standard.
