We tuned them out once we heard the “lecture” tone, some old SOB wanted to tell us how it’s done, as if he knew anything. Maturity does have value, and fish research is postulating that we’ve got the regulations reversed, and should harvest all them young and dumb fish – as their absence isn’t missed.
“It’s not the young ones that should be thrown back, but the larger, older fish that should be spared. Not only do the older fish provide stability … to the population, they provide more and better quality offspring.
This isn’t going to fly with the “Gurl’s Gone Wild” crowd, you lecherous SOB but it does give you a bit of validation.
“Stability” in fish could be “wisdom” in humans – we’ve been preaching its benefits for years, not that it’s done much good – just count the number of stainless studs in your kid’s nose for proof..
A single large fish will simply grow a little when it gets more food, or lose a little weight when food is scarce. A population of many young, small fish, however, may explode in number or collapse depending on food availability.
Translation: Old guys learned a long time ago that consensus was the root of all societal ills, the younger crowd do everything at the same time causing massive upheaval – ’cause upheaval’s fun as hell.
This is especially important to know when trying to rebuild fish stocks.
This is where the research falls on it’s face, experience has taught us that despite our willingness to “rebuild,” the “grilse” will take one look at the available “mature” genetic material – holding their breath to make their gut smaller – and the species is doomed.

At least at our age we provide the “instant contraceptive” — our own nudity.
You should probably put “mature” in quotes as well.
Yes and yes.
It has been shown that fish have an increasing fecundity with age. They are one of the few creatures on earth that display this attribute.
