Fish have what's called high mortality or low survivorship. Start with a thousand of them and see when they all die.
You should notice that at least 50% of the population dies within 15% of the known total life span.
So, really big fish are old fish and as you say, very important fish genetically.
We have a slot limit for some freshwater fish species.
Humans have the opposite survivorship curve. Odds of living a large % of the lifespan are pretty good.
