“…The compressed life history for Grand Lake stock paddlefish is similar to that reported for Louisiana paddlefish by Reed et al (1992), where high natural mortality resulted in maximum ages being less than 15 years. Other southern populations show similarly short lifespans (Paukert and Fisher, 2001).…”

on a southern Great Plains stock of paddlefish Polyodon spathula inhabiting the Neosho River, Spring River, and Grand Lake, Oklahoma, is characterized (1) in terms of the Acipenseriform life history framework outlined for the Yellowstone-Sakakawea stock of the Northern Plains and (2) in relation to the framework metabolic theory of ecology and associated latitudinal and environmental correlations with lifespan. In the Grand Lake stock, male fish typically mature at ages 6-7, and females mature at ages 8-9. The five stages of the lifespan (immature, maturing, growth and reproduction, prime reproduction, senescence to death) are compressed into a period of 15-20 years; the prime reproduction period occurs from ages 12 to 16 years for females. This lifespan compares to one of 40-50 years (and occasionally longer), and a prime reproduction period for females from ages 25 to 40 years, for the Yellowstone-Sakakawea stock. The more compressed lifespan of the Grand Lake stock and lower energy storage, as indicated by weights of gonadal fat bodies, are consistent with the framework metabolic theory of ecology. Over the course of a year, fish in Grand Lake are under a much higher metabolic demand than those in Lake Sakakawea. The distinct differences detailed between these two stocks from the southern and northern plains may exist between other paddlefish stocks, other Acipenseriform species, and other fish taxa separated by large latitudinal and climatic differences. The results have specific implications for harvest management and effects of climate change on Acipenseriform life histories and lifespan.

“…Acipenserids and paddlefish Polyodon spathula ), as they exhibit different life history strategies. For instance, female bowfin mature at a relatively early age (3 to 4 years) and spawn annually, whereas female sturgeon and paddlefish mature much later and have spawning periodicities of several years (Reed et al., 1992; Birstein, 1993; Boreman, 1997). In addition, susceptibility of bowfin to the effects of harvest may be minimized because they are not as long‐lived as other species commercially harvested for roe.…”

Bowfin Amia calva are a common species throughout the Mississippi River basin. Although they are generally regarded as a ÔroughÕ fish by management agencies and anglers, commercial harvest for their roe has increased in the upper Mississippi River (UMR) basin. Unfortunately, bowfin population dynamics have not received extensive study, resulting in a lack of information that can be used to guide management efforts, particularly in the UMR. The purpose of this study was to investigate the age structure, growth, and reproductive ecology (e.g. age at maturity, fecundity) of bowfin in Pools 11 and 13 of the UMR during the spring of 2007. 118 bowfin from Pool 11 and 138 bowfin from Pool 13 were sampled using modified fyke nets and electrofishing. Size structure, age structure, and growth were similar and sex ratios were near 1:1 in both pools. Female bowfin matured at age 3 and had gonadosomatic index (GSI) values around 9; male bowfin matured at age 2 and had GSI values near 1. Total annual mortality of age-4 and older fish was around 35% for both populations. In both pools, rates of total annual mortality of males were approximately 10% higher than those of females. Growth overfishing occurred in a simulated population with a 500-mm minimum length limit. Recruitment overfishing occurred with 500-mm, 559-mm, and 584-mm limits at moderate to high levels of exploitation; a 635-mm minimum prevented recruitment overfishing at all levels of exploitation.

“…Female paddlefish in Lake Francis Case reached sexual maturity at a younger age (age 11) than paddlefish in Lake Sakakawea (age 15, Scarnecchia et al 2007), but reached maturity at an older age than females in Kentucky Lake (ages 8-10, Hoffnagle and Timmons 1989;Scholten and Bettoli 2005), Louisiana (age 9, Reed et al 1992), and the Alabama River drainage (age 6, Lein and DeVries). Paddlefish age at sexual maturity increases with latitude, which may be explained by higher growth rates at southern latitudes (Reed et al 1992).…”

Stocking Success of Paddlefish in Lake Francis Case, South Dakota: Population Characteristics and Sport Fishery Potential

et al. 2011

View full text Add to dashboard Cite

Lake Francis Case, South Dakota, a Missouri River reservoir, supported a paddlefish Polyodon spathula sport fishery shortly after impoundment, but this fishery closed in 1986 owing to a lack of natural recruitment. Lake Francis Case has been stocked intermittently since 1974 and annually since 1990 to maintain the population and potentially sustain a sport harvest. To evaluate the success of these stockings, we assessed the current status of the Lake Francis Case paddlefish population (i.e., population characteristics and dynamics) and evaluated the potential effects of exploitation on this population. Advanced fingerling stockings have been effective, as 56% of sampled fish were of hatchery origin (indicated by coded wire tags), and may sustain a harvestable population. Year‐class strength was negatively correlated to water temperature inputs from Big Bend Dam and positively correlated to White River discharge. Downstream emigration is probably responsible for most of the variability in year‐class strength, and the rate of downstream emigration may be greater during years with warmer water temperatures. Harvest simulations suggested that growth overfishing was possible under a 660‐mm minimum length limit but not under 840‐mm and 1,016‐mm minimum length limits. The proportional size distribution of memorable‐length fish (PSD‐M) was reduced 28.6% and 14.3%, respectively, by 5% exploitation under simulated 660‐mm and 840‐mm minimum length limits. Under a simulated 1,016‐mm minimum length limit, PSD‐M was unchanged by 10% exploitation. At 5% exploitation, broodstock availability was reduced by more than 30% under the simulated 660‐mm and 840‐mm minimum length regulations and was reduced 16% under the 1,016‐mm minimum length limit. Our results suggest that this population could support a limited (e.g., 5% exploitation) sport fishery under a high (e.g., 1,016‐mm) minimum length limit without substantial changes in size structure or the availability of broodstock if stockings are continued.
