A fish hatchery has been raising large populations of endangered fish species and releasing them into a local lake. At the end of each year, the hatchery takes a sample of fish from the lake and compares the number of hatchery-raised fish found in the sample with the number of wild fish found in the sample. The table provides release and sample data for five years of the hatchery’s operation.

It's asking hatchery released the smallest percentage of the total five-year fish release.
I think it should focus on the column "Number released (thousands)"
The Number released of the 5th year (the year with the smallest number) is 600 (thousands), and the total five-year fish release is 150 + 450 + 530 + 580 +600, you can see that the 3rd year accounts for the smallest percentage.
*Percent hatchery contribution is the percentage of [ number hatchery / sample size ]
Hope this helps!
