is the year-of-the-young index out yet?

If you don't like it do something about it.
My friend started the save the summer flounder fisheries fund (SSFFF) after the NMFS told us we where going to be down to 2 fluke per outing with the possibility of a closed season the next year.Reason was NMFS statistics told us we where vastly overfishing our quota's..
He worked hard to raise money.With it a independent scientist was commissioned who put fourth numbers to dispute the claims of overfishing.It worked..And we have had a few banner seasons since..
They have more new battles now but that's a different story.
My point is if you put forth the effort you can get it done.If you think there is a problem do something about it.
Typing on websites gets little done.

I think I remember reading somewhere (Daignault) the model was changed at some time in the YOY survey..
Plus many things factor into the success of the spawn.This years wet spring could have been a factor.
If you ask me as a fisherman. I think the striped bass population has been somewhat stable the last ten years..
I think their feeding habits are changing..We have cleaner water now,that yields easier offshore feeding.I think some sort of satellite tagging program would be very interesting to say the least,.

Mike P, not to get too boring with math but geometric mean is more accurate than arithmetic mean for calculating trends (population growth, return on investment, etc) over time so the numbers Matt quotes are more relevant (and accurate) than the arithmetic mean numbers. Generally the arithmetic mean and geometric mean are not drastically different. If the geometric mean of the data differs from the arithmetic mean by two-fold as you suggest then their data is junk.

Just that the arithmetic mean is the one that has been traditionally referred to when assesing the succes/mediocrity/failure of a spawn. People are used to hearing it--when they hear "3.92" and don't know that it's the less familiar geometric mean being used, they tend to think that it's a disasterous spawn rather than a mediocre one.

It was also the one used by ASMFC to end the commercial moratorium--there had to be an 8.0 average over a 3 year period before the fishery was reopened.

The 26 recorded in 1989 accomplished this all on its own

And I mis-spoke the arithmetic mean for 2009--it's 7.87, not "a little under 10".

all this math talk is makin me hott!!!

Funny. RIRockhound and I were talking about just that last weekend.

Especially since I have been talking to the Tuna guys and they are telling me that there are tons of Bass out on Stellwagon eating sandeels like there is no tomorrow. They are offshore because their favorite food is offshore.

Matt -- you get hot looking at the pictures in the latest issue of Modern Maturity.

Mike -- thanks for the clarification. Mine was a minor point but the math was more interesting than the usual 1000 "nice job" posts after someone uploads a pic of a 15lber
