The shellfish industry needs a kelping hand in fighting ocean acidification

Ocean acidification is a daunting problem for shellfish farmers. It turns out that when the water becomes more acidic, the organisms aren’t so good at building their shells or reproducing. Oyster farms off the coast of Washington have already started to see the detrimental effects of increasing acidity.

In response, Paul G. Allen awarded $1.5 million to the Puget Sound Restoration Fund to investigate how kelp could help. Kelp and other seaweeds are able to take up CO2 out of the water, and therefore would make a micro climate of less acidic water. The research being led by Dr. Jonathan Davis , is specifically aimed at how kelps could be used around shellfish farms to create a acid buffer.

Davis is so optimistic, he has already began researching how the seaweed can be used as an additional commercial product for shellfish farmers. He is actively exploring kelp uses from food to fuel.

This multi-culture approach is really good idea. First off, these seaweeds would contribute to carbon drawdown, aiding in the removal of CO2 in the oceans. Additional benefits are protecting a farmers shellfish product while also adding a new revenue stream by selling seaweed products.
