Hey, what's up?
If you're like me, you love fishing the surf. So, check it out.
This is what Bigfoot told me.

The perch at the top is a female barred perch.
The perch at the bottom is a male barred perch.
You can see that the female has a gracefully curved anal fin.
You can see that the male has a notch or indentation in the middle of his anal fin.
One female may have only one baby daddy.
One male may have multiple baby mammas.
Now take out your scratch paper and do the following math problem:
Assume that a female barred perch bears an average of 33 young per season.
Assume that each male perch can impregnate two females per season.
In a season, fisherman Richard Cranium catches 80 female barred perch and 120 male barred perch at beach X. He takes them all home for pictures and even eats a couple of them.
In the same season, fisherman Guy Goode catches 80 female barred perch and 120 male barred perch at beach Y. He takes home 60 male barred perch and makes two-hundred gallons of fish soup.
How many more perch young can be expected at beach Y than at beach X the next season?
Assume that one quarter of perch young survive to four years. How many more ten-inch perch can be expected at beach Y than beach X?
Can you dig it?
I thought so! You're so smart!
