Short of a complete ban on dredging, this may be about the best outcome that could be hoped for at the present time. Depending on the market price, spending the fuel and time to go out for 10 sacks of oysters may not be attractive enough to many harvesters.
I'm re-reading a paper right now that discusses all the valuable ecosystem services that are lost when valuable oyster reef habitat is destroyed. http://life.bio.sunysb.edu/marinebio..._grabowski.pdf
I think this is a great way to communicate our concerns to other anglers, to state policy makers, and to CCA-types in terms of maintaining habitat and valuable ecosystem services. |
Agree with all that ^^^^
Oysters do a world of good but hypoxia (dead zones) and oysters are not correlated (you will see that its not mentioned in the the graph you presented also). There have been studies in Chesapeake Bay with hypoxia and oysters and the consensus is that oysters are great and all but definitely not a magic bullet. Oysters essentially can't operate in hypoxic conditions and shut down until the conditions pass (no filtering taking place)
Interesting on the greenhouse gases mentioned in the slide also. May also want to read some of N. Rabalais papers on hypoxia and mentions of climate change caused by humans

The world’s climate has changed because of human activities, and it will continue to change even if greenhouse gas emissions are stabilized because of lagging impacts that will last for centuries
