Growth Rates for Monster Great White Sturgeon in the Fraser River
(+244cm in length)
Growth rates were measured from 31 sturgeon of at least 244cm (8ft). Each of these fish were caught at least one time prior so that a difference in length could be calculated. Time frame between the first and last measurement ranged from 4 to 14 years.
Results are shown in the table below.
| Measured | Parameter |
| 1.4 | Avg growth rate (cm/yr) |
| 1.0 | Standard Deviation (cm/yr) |
| 3.4 | Max growth rate (cm/yr) |
| -0.2 | Min growth rate (cm/yr) |
| 1.5 | Median growth rate (cm/yr) |
| 30 | Number fish used in study |
| 140 | Number measurements |
| 4.7 | Avg # measurements per fish |
This compares with an average growth rate of 4.4cm/yr between 100 and 200cm in length.
Of the 30 fish measured, 4 showed a growth rate of less than 0.5cm / yr. It should be noted that it is difficult to accurately measure a fish of this size, and with a slow growth rate, the standard deviation is high in comparison with the actual measurement.
