Estimated operational fuel savings over traditional shellfish raft culture methods - for each SEAfarm facility: > $76,000/year (2011)
System Benefits • Product diversification • Improved environmental performance • Reduced operating risk with multiple species • Reduced CoP with shared labour pool, SEA- Power and SEA-Hatchery • Organic approach – meets growing market demand SEAVISION
Market Potential • Increasing seafood demand globally (>2.5% annually) and growing per capita consumption in North America • Growing Eco-ethical consumer base looking for fresh, sustainable, wholesome food choices – and willing to pay (organic niche) • Prices of high-valued species projected to continually increase (>20% by 2020)
