If the fish delays reproduction for 6 months, it can increase its egg production by 5 eggs per month for each of those months, resulting in an additional 30 eggs (5 eggs x 6 months) on top of the initial 10 eggs, totaling 40 eggs per month. If it had started reproducing immediately, it would have produced 10 eggs per month for 6 months, totaling 60 eggs.
