Which is the appropriate statistical test?

Why is your data in ratios? If it is weight or something you can just use a t-test. 

If you want to compare expected vs observed results use a chi-squared goodness of fit test.

Is this just the weight of black sees compared to the weight of yellow? If so perform two tailed t-test.
