. The Canadian field-naturalist. 1988 Parker: Status of the Paddlefish 293. Figure 2. Distribution of the Paddlefish in North Amerca. ^Present distribution • Former Canadian distribution The following information is derived from Paddlefish populations extant in the Mississippi River system. Paddlefish grow rapidly with a maximum size of approximately m total length (TL). Mean total lengths for adults from several mid-western populations range from 70 to 150 cm (Carlander 1969). Growth rates between popula- tions are extremely variable (Bonislowsky 1977; Pasch et al. 1980; Combs 1982).

Carlson and Bonis- lowsky (1981) report that in Missouri, maturity is attained at lengths of about 140 cm TL for females and 127 cm TL for males; and that females first reach maturity at between 7 and 14 years. Russell (1983) states that males generally reach sexual maturity at about 7 years old, females at 10-12 years. Carlson and Bonislowsky (1981) report that.
