摘要:
A study of the life history of the black crappie Pomoxis nigromaculatus (LeSueur), from Lake George, Florida, was made in 1949 and 1950. Few previous attempts to determine the age of fish from Florida waters have been made because of several difficulties in reading scales. Scale readings of 943 black crappie revealed that the 1947 and 1948 year classes were stronger numerically than the 1949 year class. The readings also indicated that few fish reached the IV group or older. Males and females showed only minor differences in growth. Calculations of growth from scale measurements yielded the following estimates of length at the end of the first five years of life: first–4.4 inches; second–8.1 inches; third–9.9 inches; fourth–11.5 inches; and fifth–12.5 inches.
