A scientific study carried out in 2005 by Ole Jakob Bergfjord of the Norwegian Agricultural Economics Research Institute reveals fish farmers handle risk better than people in other industries.

The study showed fish farmers consider fish farming to be a risky business in relation to other industries, and consider themselves relatively risk-tolerant compared to other groups. Furthermore, future salmon prices, market access and fish diseases -- key factors in their business -- are regarded as the most significant risks.

Reason for success?

Many have speculated how the aquaculture industry built a global billion-dollar industry in such a short time.
