Striped Bass growth statistics

Age Your Fish
Notes:
Average size is just the median of both weights. It is more realistic maximum in the
late fall after the striper has fattened itself up for the winter.
Feeding will slow
when water temperature drops below
50 degrees, so in the spring
the minimum weights are then
more accurate. This of course
does not apply to a roe laden
female. There has been much discussion
about the varients in
weights. There are many factors that
contribute to weight or
lack there of. A good digital flat scale will
put less
stress on the fish than than those lip grip types
and are more accurate.
A measurement should be taken while
the fish is on a flat surface from the tip of the nose to
the outer most point of the tail.
There is no substitute for an accurate scale but to estimate the weight
of your striped bass the formula is thus.
Length
X length X length /
1,950.
For example: a 30 inch
striped bass weighs ~ 14 pounds
30" X 30" X
30" /
1,950 = 14
Use
your calculater and the above formula for a fair approximation
Margin of error up to 6%
The Formula for following
species is thus
Bass weight = (length x length x girth) / 1,200
pike weight = (length x length x length) / 3,500
sunfish weight = (length x length x length) / 1,200
trout weight = (length x girth x girth) / 800
walleye weight
= (length x length x length) / 2,700
For example, you
catch a 16 inch walleye. Using the formula for walleye
above: (16 x 16 x 16) / 2,700 = 1.5
pounds. Your walleye weighs
approximately 1.5 pounds.
