Key points in bio-security design
• Site selection
• Water intake treatment
• Super structure
• Staff & visitors
• System design
• Operation & production planning
• Site infrastructure
Your Aquaculture Technology and Service Partner
Site selection
• Avoiding diseases is key
• Water quality most important
• Fresh water, river, stream, well, borehole
• Saltwater intake, beach drains or similar
• Other nearby farms?
• Other risks?
Your Aquaculture Technology and Service Partner
Water intake treatment
• Treatment, almost always
• Mechanical filter or sandfilter
• Ozone treatment
• UV
• Aeration
Your Aquaculture Technology and Service Partner
Super structure
• Insulated building always
• Minimizing impact from outside
• Risk limited to deliberate input: Water, air, people, feed etc.
• Heating/chilling (titanium if seawater chilling)
Your Aquaculture Technology and Service Partner
Staff & visitors
• Biosecure entry - bench
• Wellies
• Hand desinfectant
• Coats
• Visit in the right order
• Staff foot baths
Your Aquaculture Technology and Service Partner
System design
• Fish logistics – flow
• RAS design ”state of art”
• Input: Eggs only
• Fish out at other end
• Grading platform
• Vaccination - injection
• Salt treatment system
• Dead fish collection & disposal
Your Aquaculture Technology and Service Partner
Operation and production planning
• Only eggs in and desinfected
• ”All in - all out” for incubation, first feed, fry
• Smolt and On-growing overlapping
• Fauling of RAS?
• System desinfection for all in all out, NaOH
• Biofilter start-up, inoculation
• Daily operation and hygiene
Your Aquaculture Technology and Service Partner
Site infrastructure
• General process flow & no cross contamination• Water intake/treatment• System design flow• Automated central feeding• Central lime (pH) & salt dosing• Lorries in out (feed, mort, sludge)• Well boat of fish trucks• Staff logistics• Waste water treatment area• Morts collection & disposal
