While larger fluke will have more eggs , it’s claimed older fish carry eggs that are not as fertile .

In one breath you're saying commercials prime size fish to target are over 4 lbs. and then you say a majority of the biomass is made up of fish under 18 inches. How many 4 lb. 18 in fluke have you caught in your lifetime?
The people saying larger fish while having more eggs are less fertile than younger age classes are the same guys harvesting those older breeders to rationalize their catch. The juvenile female fluke when they first attain sexual maturity are said to produce approximately 400,000 eggs a year. Large breeders can produce up to 4 million a year.
There might be some truth to the fact that larger breeders on a relative basis are less fertile but there's no science that suggests that differential in fertility comes close to mitigating the incremental eggs a larger breeder is capable of producing.
