General remarks

  • Major obstacles:
    • There are no obstacles for our technology.
    • Changes in filtration systems, type of tanks, inflow and outflow makes our system suitable for many species.
    • Obstacles for the fish farming industry in general are bad suppliers and bad technology.
  • Future expectations:
    • The worldwide introduction of the HESY BLUE LABEL SYSTEM, with less energy requirements, less waste, better results and lower production costs.
    • The technology of fish farming is good but will constantly be improved.
    • The market for farmed fish will grow because of pollution of open waters, lack of water, restrictions to discharge, catch quota, problems in the meat market et cetera.
    • More people will eat fish instead of meat.
    • While the systems are suitable for many species we shall enter new markets for our systems in Asia and South America.
