I hope this happens soon

I didn't manipulate the inputs because the numbers don't support my statement, but I will say it was a mess. I was trying to make a comparison so people can see the impact of removing the big fish. It wasn't valid, but I was starting with numbers that you provided for three fish, which assumed all 28" fish will be female .

Even comparing females to females, my statement is pretty accurate.

Year 1:
3x 28” (10# each) fish produce roughly 2,125,000 eggs
1x 40” (26#) fish produces roughly 1,985,454 eggs

Three 28" females produce on average 7% more eggs than an average 40". But start harvesting and you won't get all females. And the numbers are estimates so that 7% is probably +/- 3%.



This is it for me... I agree my explanation wasn't great and I probably should have said 5 or 6 28" to one 40". Here it is in the most basic form, but including males and females:

A group of six 28" fish (3 males, 3 females) produces about 2 million eggs. A 40" fish, almost certainly female, produces about 2 million eggs.

An average harvest of six 28" fish will remove almost the same number of eggs (~7% more, to be as exact as possible) as removing one 40" fish.

It is even more dramatic if you compare a 24" to a 44".
