The article state that the most successful survival group of hatching stripers are those that have come from eggs with large yolk sacks. This happens when the females are about 10 years old or older. a look at an age vs length chart will show that these best breeding females with eggs that have large yolk sacks happens at a length of about 35 inches. They certainly do produce eggs that hatch successfully before this but at about 10 years old/35 inches , the survival rate of the hatched eggs goes way up do to the availability of the food in the well developed yolk sacks. Also this size female produces many more eggs as well as the more well developed eggs.
This single fact alone says that the "keeper" size limit for maximum spawning success should be somewhere in the 35 inch range , give or take some for average vs high and low lengths vs age.
