I can only imagine how abundant the fish were back then. I bet they used handlines to bring in 70+lb bass. I wonder if they livelined pogies, or just threw out the chunks?

Something I posted today about spawning:

The way I understand females dumping their eggs, is that if a female is carrying 5 million, she might not dump all of them during the spawn. To carry 5 million, she would (theoretically) have to be in the 40 or 50lb class. The females in that size class can behave differently when compared to the females in the size class from 30-38". (More on this when I get a chance to come back here and go into more detail.)
2. To try to specifically answer your question, what % of bass make it to maturity from an original spawn? it's pretty difficult, and even scientists have slight disagreements.
Generally, the research papers I've read claim that about 0-20% of the eggs let loose from a fertile female, will make it to the fry stage.
Some have defined this stage as when the bass is 45-52 days old after hatching. At that point many environmental hazards, and bulk of things that snack on these eggs like a quick protein shake are eliminated. Remember it's up to 20% (only in optimal cases, most likely less).
What is left from then on is bigger fish of all species as predators. --
Out of that number, some studies have shown that at least 3/4 of the remainder will not make it to adulthood to join in the breeding cycle again (about 4 years)....
3. So, your point about a small % of bass making it to adulthood, is a good one, and probably very close to reality. You could use a number of less than 10% survivability, and that could be pretty accurate.
(Could even be 1% or less as you suggested.....)
**You could use a range of 10% down to 1%, or less that will survive.
A. Assuming a 30 lb bass containing 3 million eggs, if all eggs were dumped out at one time, even with the worst case scenario assuming only 1% of the eggs survived to become adult bass,
that is 30,000 bass from one 30 lb breeding female that will make it to adulthood..
B. If you take a pessimistic view and assume only half that amount,
that is 15,000 bass coming from one 30 lb breeding female, that will make it to adulthood.
**Remember that the above figures are subject to a lot more variables than I have explained here.
The question of what that % is, can vary from year to year.
Something I could come back and go into detail on, if anyone wants to hear it.
Awesome info thanks for sharing ds.
http://new.coolclassroom.org/adventures/explore/fish/10 may be elementary for most here but I found it a good read when you get up in the pages around the twenties.
Thanks for posting rob. Good info about how to interpret sea surface temperature too
Have been doing some research on hybrids and discovered this about the market for the East Coast.
Thought some members would find these articles interesting.
