Agreed time to move on.

Yes, that is what I was saying. In other words, you would have to kill at least three smaller fish to equal the loss of one large breeder. Add in the fact that maybe half of small fish are male, the equivalency is more like 5 or 6 small fish harvested has the same impact as one breeder. Plus the small fish grow faster whn there is less competition in the school.
The math is based on fecundity and recruitment. I am not making statements about what I think, I am reporting the scientific properties of population dynamics based on what I was taught and what I have read in scientific literature. If it has changed, I really would like to read those studies. There are hundreds of studies and I haven't read them all, that is for sure.
