Biorock® oysters grow faster and have higher survival

SUMMARY OF 2007 & 2008 RESULTS
Nikola Berger, Mara Haseltine, J. T. Boehm, and Tom Goreau

Measurements made in flow through tanks using bottom water from the Hudson river off midtown Manhattan over two years found that oysters with Biorock® treatment had 2.75 and 1.62 times faster growth rate than controls in 2007 and 2008 respectively, while the control oysters had 2.08 and 1.36 times higher mortality than Biorock® treatments. This data therefore strongly suggests that Biorock® oysters grow faster and have lower mortality, indicating that this method should be highly applicable to restoration of oyster reefs.
