Need help here

Ok so i got a bunch of data here and i'm a little confused how to go about it.

let's say we have 4 rivers : river 1,2,3,4. Rivers 1,2 are in river basin 1, while rivers 3,4 are in river basin 2.
In each river 4 fish were caught and were measured
Measurements (Total length, standart length, head length, weight)
I have to compare these morphometrics between rivers and river basins with ANOVA.
I don't know how to go about it because i don't understand the hints i was given (sorry for the lousy paint).
What would be the correct way to do this ?

He told me to do a table like this but i don't this this is correct

He told me to do a table like this but i don't this [sic] this is correct

So 'he' is making false statements or, even worse, lying?

Research ANOVA until you understand the connection between the data and the hint. Also research Berne's game called "Yes, but. . .".

Looking at the table i drew it looks like he wanted me to compare, say all the TL data of all diferent rivers with SL, HL and W. I just wanted to ask is that logical ?
I would invert the table and compare , say first river's TL, SL, HL, W with second river's TL, SL, HL and W.
