Such cute creatures sway public opinion. The oyster spat settled, attached, and then died. Some of it was fresh water flooding to keep the oil out, but they also died at the proper salinity. They are now saying seven years, where oysters harvest in two. The dispersant seems the cause.
There is no telling as many gulf fish spawn in the marsh, and the young go offshore. Some species may become scarce, in years to come.
Fish we do not fish feed the tuna and whales offshore, Like DDT and Dioxen they move up the food chain. Whales eat tons.
It is also the bottom of the Mississippi Flyway, millions of ducks, geese, cranes, winter in the marsh. What will next years egg hatch in Canada be like?
This is most of the wetlands in America. Birds, fish, shrimp, crabs, oysters, had their one good spot left. Oysters are functionally extinct worldwide, over harvest, pollution, the Gulf was the last strong population.
The Exxon Valdez many years later, the fishing never recovered. Loss of the breeding stock, a few spawn runs, and the population crashes, and can take decades to reach a strong breeding population again. Fishing can be good for years, those coming in from the ocean, before the missing generations show up.
We will not know the result for decades.
