Shovelnose Sturgeon, Age and Growth, Mississippi River
Anterior pectoral fin rays and body measurements were collected from 110 shovelnose sturgeon captured from October 29 through November 5, 1971, in pool 13 of the Mississippi River. Fork length ranged from 7.4 to 23.7 inches and weight ranged from.06 to 2.02 lbs. The length-weight relationship was estimated as log10W = -4.292 + 3.307 log10FL with standard deviation for the regression coefficients ±.046 and ±.038, respectively. Condition factors (C) averaged 11.6 with a range from 9 to 17. Mean lengths at time of capture were 8.9, 13.7, 18.9 and 22.0 inches for age groups 0 through III.
