5 Offshore Aquaculture A brief introduction and ideas to apply for Tasmanian Exposed Salmon Farming By Joachim Buarø, MSc Marine Technology

6 Background Joachim Grew up as part of operations family owned fish farm MSC Marine Technology Speciality Marine Operations Thesis «Installation of suction anchors» Master thesis «Float-over installation of platform deck» Since 2000 using offshore technology in the aquaculture industry worldwide

8 Demand for increase food production Growing population Growing demand for food 2% 32% ocean based production land based production ocean land 68% 98%

9 Why fish farming? On the limits of wild catch

10 Why marine fish farming? Efficient production of salmon for human consumption in natural habitat

11 Why salmon?

12 Where to grow? Hurricane tracks

13 Current situation Tasmania Demand for growth, but: Limited space Environmental challenges Biological challenges

14 Examples enclosed Aquaculture Innovation Initiated august 2016

15 Examples enclosed - Preline Initial production may 2015 Some experiences: In open ocean sites 8 months 50g to 5kg Improved fish health and reduced environmental impact More robust slime reduce lice issues No disease Minimal mortality

16 Offshore aquaculture brief introduction Offshore aquaculture, or open ocean aquaculture, is an approach to mariculture or marine farming here fish farms are moved some distance offshore. The farms are positioned in deeper and less sheltered waters.
