I have been assigned with the data analysis on some marine science research, but I am by no means an expert. I was hoping to get some advice on what test I should use as well as how I should set up my data. I think I need to use a one-way ANOVA but am not sure. My research question is: Is there a significant difference in the amount of fish between different artificial reef types? The details of the data set are:

-5 different surveys, each split into two days (the first day is at location #1, the second-day location #2) over a period of months between 2004 and 2005.

-In each survey, there are 5 different reef types, with two repeated measures (amount of fish) for each reef type.

I would also like to test to see if there is a difference between the two locations as well. I am no data scientist so any feedback would be very helpful! Thank you.
