Summary
Thousands of fish died belly-up in a marsh in Louisiana. No one really knows what the main reason why the fish died and they don’t know if it was just everything conspirering against the fish because fish decompose so fast that it's hard to get a fresh enough sample. Kevin Kleinow, a LSU fish toxicologist, said"Very surprised if someone was able to definitely determine the cause of death" for these fish”. Some theories of the fish death is that the agricultural runoff that goes into the Mississippi River contains nutrients that help the growth of an algae bloom that is oxygen-hungry. As the algae oxygen level goes down, the fish will choke. Anouther reason of the death of the fish can be the oil spill in the Gulf of Mexico. This is causing a serge of oil-eating bacteria that take up oxygen. This expands the low oxygen dead zones. The last fish died at the time of the year when dead zones expands.
Opinion / Reflection
I was surprised about the death of all of the fish and that they will wash up on shore. One this will have a huge affect on an already messed-up ecosystem. Also this will make it harder to fish in areas where the fish are dying by the thousands.
Questions
1. How many fish died?
2. What is one way that could have had been the main reason the fish died?
3. why is it hard to get a fresh sample of a fish?
