Default Salinity and Crawfish

I am in 10th grade and I am doing a science fair project on how high salt levels in the water since the Hurricanes has negatively effected the crawfish industry in Louisiana. I am in Louisiana, should I just go about testing the salt levels of different crawfish farms and comparing them with past figures? Any ideas?

Post Very Good idea

i think it is a good idea, but you have to know it crawfish really does not like high salt level, wait i'm kind of confused, if you want to do this, then you have to find data on crawfish production in Louisiana, right?

yes, i know that the salt has negatively effected them from news reports I read. I was just going to test to see wich ponds still have high salt water.

Question Reply

so, you're going to test ponds that have high salt level in it and its negative impact on crawfish, i thought you are doing in on crawfish production?

well i was going to compare production levels at this time last year to those currently (way lower in most areas) and then show that the production levels are still relatively normal in Northern Louisiana where the area was less affected by the hurricane flood waters.

okay, but you have to demonstrate the affect of salinity on crawfish, that may be a experiment; you know, you should catch (two) crawfish and put them in a high salt environment, then you should observe what will happen to them because by only comparing the production level itself is not a project for science.


good luck!

I like Pluto's idea, because that is more controlled.

But I don't see the problem in doing both... But for your previously planned experiment, make sure that you can find the stats that you need. And do research. Then you can try bringing the crawlfish into the controlled environment.

Good luck!
